Very nice Mike:thumbsup: Rifle details?
where is the target that was goint to be the standard? ddnt some one put up a target that was to be shot at for the challange?
I have a wee 7mm that was test friered tonight, rem700 S/A as a base an can push the 180gr bergers at 3200 accuratly:thumbsup: real accurate................i cant find the target to print out but will an will shoot if with witness, this thing blows me away:thumbsup: want it to be mine now:x_x:
Good shooting there mike h
I personally like this one as a challenge
yds?
Its a rifle called a Tikka T3. They're not very common but if you look around you can find them ;)
This one is the .308 which I wrote about in the firearms section which has just been shortened and fitted with a Hardy suppressor.
Load is 165gn Sierra Gameking HPBT, once fired Winchester brass that was trimmed, primer hole deburred, chamfered, primer pockets cleaned, neck sized with a Lee Collet die etc, 46gns of AR 2206H powder(above max), Federal GM210M primers for 2660fps(at 6ft) and OAL of 2.67" which is well below the typical 2.801" length that most .308 ammo is loaded to. At this length though the projectile is touching the lands due to the long short distance back from the tip that the ogive is.
I had a rushed attempt at the challenge last night, barrel got hot so was dealing with a lot of mirage. This rifle will shoot .1" if you take your time and use a finer aiming point. The bottom 2 groups are actually 4 shots with the bottom shot of each being adjustment checks, The biggest group was .47"

I have been playing with my 7mm mag floating the barrel and stiffening the stock. I wanted to see what difference the bipod made in point of impact so shot a couple of groups. Not 5 because it would take me all night to do that and let the barrel cool down between groups.
Fired one sighter then a group of three off the bags

then this off the bipod

no shift in POI when going from bags to bipod, I have found that to shoot groups like this with the 7mm mag it is best to allow your cheek to rest heavily on the cheek weld (although you probably want a soft one) I have shot a few groups like this with this rifle now.
Sorry about the pic quality, it seems i over compressed them
115m over a box and Philipos Tactical Buck-wheat pillow - laying downhill
Gun is a Ruger 253 with the Paddle stock - wont shoot more than 2 rds onto A4 with factory ammo, has 6" of rotten barrel about 3" back from the muzzle.
Spanners Super handloads fixed that :super:
Group works out to be under 0.108 at over 125 yds :cool:... soooo 0.08 MOA??

I thought thepoint was to do 5 groups not just post one good group....:P
:D not yours on its own, everybody seems to be doing 1-2 group tests and posting them which is the complete opposite if what Gimp was talking about at the start of the thread
Tussock - I found the cheek resting heavy had most noticeable results in rifles with higher recoil, it seems to help make the recoil more uniform. Dont know the exact science but it works and is on its own makes a huge difference in shooting consistency
I have a strong feeling that the harder cheek weld is probably promoting better follow through, which makes a big difference to accuracy and consistency. I see a lot of shooters who seem to be in a big hurry to get the rifle off the shoulder and the next round chambered before the bullets hit the target ( figuratively speaking that is ).
Regular barrels are thinner and heat up faster. The forth and 5th shot are more likely to be fliers than with a heavy varmint barrel. Thats why the tikka sporter is guaranteed to shoot 5 shots inside of 1 MOA at 100y instead of the 3 with a regular T3. I'm a recent convert over from competition Air rifling - the sporter is my first firearm, though 16 years ago i was in the Infantry. I've only put 40 rounds through it in total and you can see it has potential. It is still set with a heavy trigger too. I slapped a Falcon Menace 4-14 scope on it with Burris Zee rings. All very much basic extras you'll all agree.
Thats std Federal black tips on the left and Lapua in the middle and right (still managed to flick one somehow). Once i use up my 200 shiny Lapua factory loads and begin handloading I'll see if i can meet this 5 group 5 shot MOA test. Do i get a medal if i pass lol? or at least a discount coupon? I reckon all these 'sub MOA' rifles are exactly that, BUT... i'm personally only impressed if you do it prone or sitting. I'd be gob smacked if you did it offhand!!!

I'm still getting used to the rifle but i'm sure i could do much better with the Feds - i just ran out of them.
Why is it cool to shoot 5 little holes close together not that close to where your aiming?
So it's just to prove that your rifle shoots consistently, nothing actually to do with the shooter, or hunting. Kind of understand but don't see the fun in it myself.
I was over at Barnard Pecision seeing my mate Steve and getting some stuff sorted when I saw his flash looking 10 /22 .Steve started telling me it was pretty accurate -now semi autos and accuracy sometimes leaves a bit to be desired but he assured me this thing could drill 1 hole -yes thats right 1 hole .A little later I asked him from how far did he drill these single hole groups -he said 10 yards :thumbsup:
Get a fck job lol
Working up a load that suits your rifle and being able to shoot a group sub .5" isn't as easy as it sounds, You and your gear have to do their bit... but once you have it sorted it gives you confidence in your gear, then its up to you the shooter to do your part. Once I have the rifle sorted the practice I do is free standing at 250mm gongs at 100-200-300... well 300 I use a larger gong and that gives you hunting practice
Oh and most of my groups are shot off bipod in a way that can be done in the feild so its all practice and getting to know your rilfe
It seems to me that you guys who do this mostly have had a fair amount of time with rifles, hunting etc. I didn't get the group thing no where near the centre- that baffled me a tad. For me to go somewhere where I have access to 100 - 300m for target practise is the farm I shoot. And If I'm going there with my gun I'd rather shoot something for the pot - because I am still new to this hunting. But I am having a bit of fun with my .22 Anshutz and targets up the forestry on a Sunday arvo. If I could afford rounds for my centrefire I would practise with that a lot more. Currently all my rifles outshoot me.
I didn't mean to sound like I thought that pin hole accurate shooting you lot get up to was easy - far from it. I wish I had the time, money and skill to achieve that.:cool:
Umm. Where shall we start.
Assume the firing of a shot imparts energy to the barrel, and each shot imparts roughly the same energy (over simplified I know but a reasonable approximation). The steel has a certain heat capacity and we'll also assume that it same material is used in both a skinny hunting barrel and a heavy target barrel. The mass of the target barrel will be greater so the average temperature rise in the heavier barrel will be less per shot. Also the heat will travel reasonably quickly through the metal (being a good conductor) and the dissipation of heat will therefore be more dependent on the interface with the atmosphere, and the rate will normally be expressed as an amount of energy (ie speed) per given AREA per measure of temperature difference. Since the heavy barrel is wider it will have a greater surface area and hence dissipate the heat quicker, certainly to start with the hotter skinny barrel will loose energy faster, but the heavier barrel will always be a lower temperature.
Yes doing engineering I lived and breathed thermodynamics for months.
Unless the rifle has a defect i'd say its more a case of the shooters personal skill (hence the fun). It goes to the core of marksmanship too. Being able to hit the same point everytime as opposed to the other guy. But you're kinda right - there's the other side which requires you to be able to hit random distances with one single shot. Also very hard to do. Personally i'm yet to find a boring sport involving firearms. Its all good to me
Being able to hit at random distances with a single shot is very, very difficult, especially as those distances increase in randomness.[ if that is a word]
I have seen esteemed members of this fine establishment miss first shots at under 300yrds with rifle and scopes combinations that will shoot 5 shots under an inch at 100.I have also seen these same guys take first shot kills out to 500.
To me, shooting good groups is basic, it must be done at a nominated range, mostly at 100yrds, to enable the shooter to have confidence in his/her ability and the ability of the rifle. Confidence in your rifle and your own ability, is to me at least 80% of the equation.
The harder 20% is reading the wind on longer shots.
G'Day Fella's,
Here is a 5 group shot with my .22-250AI.

I'm not sure what the rifle is capable of shooting, as it would need a better BR shooter than me, to do it!
Doh!
Homer
Gimp posted a challenge and so far in this post I've seen a few good groups but not 5 good groups, I have attached 6 targets all are 5 shot groups, 5 were shot at 100yds and 1 was shot at 200yds. All groups were measured independantly, all of the groups were shot outside with the wind doing what it does with bullets. Conditions were switchy and gusty.

http://i21.photobucket.com/albums/b2...hooting/T1.jpg http://i21.photobucket.com/albums/b2...hooting/T3.jpg
So 0.192" + 0.242 + 0.211 +0.222 + 0.193" = 1.060" divide by 5 = 0.212"
0.396" divided by 2 (to get the 100 yd measurement) = 0.198"
1.060 + 0.198 = 1.258 divide by 6 (to get the aggregate of the 6 groups) = 0.2097"
Can this rifle do this all the time YES if I feed it the ammo it likes and I do MY part........the limiting factor is can "I" do this all the time "NO".......Kiwi
Impressive:thumbsup: Rifle/ load details?
http://i222.photobucket.com/albums/d...e/IMG_7696.jpg
an example of the shooter not doing his part with my light rifle in 7mmSAUM.... Didn't let the rifle cool enough between shots, fluffing the odd one including one shot at the wrong target :o
3 shot groups are easy but with a light barrel and warm gun and starting to snatch the trigger (light rifle, no break and 180's doing 2700+ recoil is getting up there a little ) those last to shots quite often stuff things up. Recoil flinch is defintly part of it and I need to do more with the 243AI again to stop snatching at the trigger...no chance of whatching the impact with the 7mm :P
I should have taken more rounds for the other rifles I had there to do some free standing shots between shots with the 7mm so it let it cool me...to impatient...
And I will sort a break one day
The 140 VLD's and AB's shoot very very well just run out of puff at 700 and more importantly hard to sort windage in the valleys we shoot, Mostly 600-700 across so the 180VLD is the ticket. It doesn't seam to like the 160AB and 162, Just can't get reliable groups with them ?????
Never shoot more than 3 shot quick lots in the feild anyway and in the field flinch/ recoil is less of an issue. Those groups were the last for the day so allready had 25 rounds of 160's at 3K which kick just as hard so hense the snatching at the trigger :P Looking at getting some Barnes 140's for bush but the mag length 180VLD still shot pretty good so will try that on animals first :)
I have a .223 that wont shoot 60-62 gr pills but shoots everthing either side. Annoying.
Where do the lighter pills lose it leathal, wind, stability or your just not happy with them.
Just reread your post properly. Gotya. I use 130's in my 6.5 and it is around the same, about 700 it loses it in energy. But I still in fair/good conditions push it further on targets. I like trying to nut out decieving winds. just dont like wasting the ammo it sometimes takes doing it
Lighter pills, the 140VLD has blown up to close (muliple exit holes even on goats) ...and the AB has penciled out further. Wind and lack of energy is the main reason I dropped them, the AB I would keep for a bush load if the POI was the same as the 180VLD but its not and I dont want to have to dial back to a different zero for the bush load. Will try the POI for the barnes but the 180VLD should be OK still up close.. I hope...
sing out if you want some 140 ttsx to try, can spare a few or a box if you need.
Terminator, yes those groups were shot in competition with a target rifle, were the rest of the groups as good as those "no" finished with a 0.29 agg for 15 x 5 shot groups at 100yds and 15 x 5 shot groups at 200yds, making a total of 30 x 5 shot groups.
I have several "hunting rifles" that are occasionally able to shoot groups like those pictured but even they can't shoot aggregates as good as my target rifles.
Taking into account the shooting positition and the rifle used for competition and what is able to achieve, do I thing a shooter with a hunting rifle shooting off a bipod or even a bench and rest is capable of shooting 0.25moa consistantly "no" how about 0.5moa my answer to that is "show me"
veitnamcam was that question directed at me?? If it was rifle is a Bat, Kreiger barrel, 6PPC and enough 133 to almost fill the case, 68gr bullet travelling at around 3450fps.........would this load be safe in a Sako 6PPC most likely not so I won't list the actual powder load.

Yea cheers was just wondering if it was a custom or a factory
very little wind, center first with a mag box length, Rifle was shooting high and right with the 162 amax and Munster Jnr was sighting his 308 in and need help hense the wrong target shot after being distracted in the first group...then top two which were at two different seating depths then the lower left, Lower left was with Retumbo as I am nearly out of 2225 so I will have to tweek the load a little by the looks but I will load the remander of what I have in 2225 to the top right setup as I know I pulled number five on that. I caught myself shutting my eyes while snatching the trigger on a couple of the later shots in the groups. More time needed on rifles like my 243AI as I have not shot much of late and that is a pleasure to shoot with the suppressor on and is just as accurate and the Rum that is loud but doesnt kick so between the two the flinch gets sorted pretty quick :)
