Anyone got a good working load for one of these ? ? :)
I have a couple, I will take a look when I get home,
What projectile are you using?
Yes, same question as DAF and what barrel length? I can give you a common one used in F-Class but don't know if that is your intended purpose.
From memory only... 55.8gr n560 with 130gr vld's worked really well in Blair's 6.5. Lapua brass & Win LR primers

The load I am familiar with (not as a user, I shoot a vastly superior 6.5 Ackley :cool:) is 48gr 2209, 139 Scenar, Win Primers, Lapua Brass, ave 2930fps. In a Barnard action with 32" barrel. Note this is approximately 2grs above ADI max recommended load and is not the maximum that some shooters I know are using. Without knowing intended use, action brand, barrel length this load may have no relevance for you and could be downright dangerous.
140 Amax is the projectile, and the ADI max in 2217 is only doing the stated 2690ish, which for a 284 seems awful slow. That sort of speed is never going to realize the rifles full potential methinks ? ? Have made up 2217 @ 54,54.5 & 55 to try, and also 2209 @ 47.5,48 & 48.5. Most of the internet data available has the 284 at 2900+, so I'm aiming for around 2900 and will fine tune after the trial loads.
It's a hunting rifle( I've forgotten if it's a Tikka or Rem700 ) std braked barrel. Lapua brass, CCI mag primers.
I was wanting confirmation that the loads were on the right track, and I think it seems they are ? ?
Thanks for the input guys :thumbsup:
24" trueflight isn't it?
130 swift scirocco another good hunting pill red, push do hard an fast an work real well.
Not much help other than that :o

Mine has a 30" Barrel,140Amax,RL17 Powder 48Gr -2970fps, 49Gr-3070fps
Wow RL17 in a 6.5x284 Your keen:D
100 fps out of 1gr?
it's only a Barrel, i can get another one :D
the chrony showed 100 fps difference between the 1gr of powder when we worked up a load for it, I ended up going with the 48gr as it was slightly more accurate and 2970fps was near enough
I also have plenty but I don't use it anymore. Whats your round count so far on your 6.5x284 Duck Gunner? Do you find your barrel time consuming to clean?
Wanna sell it

Up to 190 rounds down it LR, it cleans up pretty easy
Yep thats what i was thinking to. RL17 seems to achieve good velocities and accuracy in a lot of different cartridges but it sure has its drawbacks.
what are the draw backs? I'm using it in a wsm, seems to be accurate and fast, its all I have tried however. is it a renowned barrel burner or something?
It does eat barrels very fast if you are running high pressures, and harder on the barrel than most powders in general. I have also found it to cause a lot of carbon fouling.
To be fair its probably gained a worse rep than it should have, as most people that have used it have done so to try to achieve high velocities and thats how a lot of the barrel damage is done.
cheers for that, maybe when I chew through my next pound I will try something else. what would ya recommend for a 300 wsm?
RL22 is worth a try.
RL 22 and 25 was way too temp sensitive in my cals. I have a couple lbs of both I will flick off if anyone wants them.
R93, PM sent regarding the powders
Actually 23" TF.
Tried those loads out today, but still a bit slow, both loads ended up at or just under 2800. Have made up more, going up in .5gr increments.
Am now at 4-5gr over the ADI max recommended loads with no pressure signs at all. It seems that most of the loads I've made up for my rifles are similarly over recommended loads, and the only use the ADI book is for is to give you a starting point at their max load :wtfsmilie: Have other shooters also found this is the case ? ?
Are you 100% happy with your chrony? I had a 24" barrel 6.5x284, it was hard to get any good speed from it. Id say try N560 and be prepared for a reasonably short barrel life.
This is a really interesting thread
The chrony is a CED M2 with IR screens and appears to be working well, so yes to that, although I would like to try it against something else in tandem.
What speeds were you getting with yours LR ? and what loads were they ?
The rifle is for a hunter that won't be trying over 4-500m so there isn't any point in trying to bust a foo foo getting max speeds, but rather get sensible speeds for max killing power.
I could only get to 2850 with 2213SC safely. I was trying to stay with ADI powders but went to N560 for about 75fps more, (140 Bergers) In hindsight I don't think a short barrelled 6.5x284 is any better than a 260.
Hey Red, you could always go to a 130 berger or swift and gain a bit of speed. I did get more than 3000 using 130's easily before Abe replaced the barrel, with the improved .260 and 10 grns less case capacity. I would have been happy with around 2900-2950.
If your mate isint going to stretch it beyond 500, it may be an option.
The swifts are accurate and frigging kill well around the muzzle velocities you should achieve with them out to around 700m.
Who really gives a shit about barrel life on a hunting rig anyway?
If you dont get the barrel hot you should easily achieve 1000-1200 hunting accuracy life which should be achievable out of any fast 6.5 cal.
I can tell you now you can distory a 6.5-284 barrel faster than 1000 rounds. If its a mans only hunting rifle 800 rounds goes quick. You also need to tune the load as the throat wears. I still think 6.5-284 is not a good round in a short barrel, it just dosent seem to make the speeds it should.
Goes without saying really. There are way too many factors that can effect barrel life. However if you dont get them hot by firing fast strings with whatever load, you will increase your chances of it maintaining its accuracy longer. No?
800 rnds would have taken me almost 10 years too get thru on deer when I was meat shooting. Thats a lot of animals if it is your main deer/thar/chamoose rig.
My 6.5-06 had 500+ thru it and it ran all sorts before I settled on N560. The seating depth changed by from new by 4 thou. Its a cal that would be as bad on barrels as any 6.5 imo.
Maybe it went so well because of HBN, dunno. Its accuracy only seemed to improve by 500rds.
Never had a 6.5-284 but find it sort of strange with almost 10grns more capacity than my .260AI you couldnt shoot 2900ish comfortably with a decent pill/powder combo with a 23-24" tube.
You were meat shooting and fired less than 80 rounds a year? The 6.5-284 will run a 140 out at 2900 from a 24" barrel no problem, it just seems to need the longer barrel to achieve the 3050 or so that it is capable of, it only seems to match a 260 in the shorter barrels.
For me, even though I go through a lot of rifles I want a reasonable barrel life because by the time I have finished playing with them from new they will have fired 200 or so rounds.
Umm, yeah? 80-85 rds average, maybe the odd yr I fired a few more. I wasnt meat shooting when it was piss easy (60's-70's) and apart from a brief stint full-time I did it part-time too suppliment my Defence force income then my awesome line pilots wage and of course because I loved it every second of it.:thumbsup:
As I said, I never had a 6.5-284 so wouldnt know what they are or are not capable of. I have a .260 AI that easily gets 3000 with a 130 so I would have thought a 6.5-284 would have been better with similar barrel length. I guess not.
So if barrel life wasnt an issue.. ie on a hunting rifle, what would be 'the' 6.5 calibre to choose? 6.5 wsm?
Obviously a 6.5-408 Cheytac Imp would be the go to.:D
The last lot loaded and fired on sunday worked out pretty much as hoped, with the top loads averaging 2869 for 56.5 of 2217, and 2870 for 50 of 2209. The groups slowly getting tighter as the speed is increasing, so that's a good sign. No pressure signs at all, which is also a good sign :thumbsup:
Will now sneak up on the 2900 wanted, watching for the magic group to appear !
Still using the 140 Amax, so will stick with them until the load is sorted then give the Bergers and Barnes a go as suggested.
Wahooo, fun city ! ;)
im using 49.5gr r17.burger 140vld.groups good.3020fps avge
I've got the speeds up around the 2900 I was after, but having trouble getting consistently good groups. I'm getting horizontal and vertical groups from the same loads, with the odd good group thrown in. It's at 50.5 of 2209, 140 amax, and I'm varying the oal .005 at a time seeing if it will come right.
Tight bolt lift is a frustration at the moment, most are tight, with a few that aren't, so I'm beginning to suspect some of the brass ? Primers don't show flattening at all.
The first loads I made with the Lapua brass that came with it had to be put through the body die before they would chamber.
The bolt is generally tight to close at the last few degrees of down with all rounds, so I've checked headspace as much as I can with .0035" paper, and the bolt will start down but only just. Anything thicker and you can't get it to start down even.
Does anyone out there have a definitive figure for headspace ?
I don't have any specific measuring tools for it, ideas ? ?
I would start with a new batch of brass Red and then see how ya go. Compare it to the stuff you have used as well. If the shoulder is bearing on the chamber it can be causing eratic groups. If you want too persist I would trim them to length then bump the shoulder till they chamber easily and then bump them another thou after that.
Personally I would try new brass and go from there.
