I think you should just stick with the 2209 @dannyb looking at adi pistol data for a 15inch 7mm08, 2209 is 50 fps up on 2206h and 2208 as well. They are cramming 45.8 grains into the case at 2.8 inch coal though. Plus you know 2209 works, it's temp stable, and the really big plus, you have a shed load of it already :thumbsup:
If you want to tutu, then tutu away! I get what you mean when you say it was too easy but sometimes easy is good lol
Too late :yaeh am not durnk:
I have traded all my 2209 for 2208.
I just wasn't comfortable with how compressed the loads were and I normally don't mind compressed loads (the amount of force and crunching whilst seating was a lot) I couldn't run a longer COAL due to the short mag length in the mod 7 so no way to reduce the compression without dingle feeding and that wasn't happening either.
Have just loaded a ladder with 2208 in new Norma brass and will shoot it tomorrow see how it goes.
Have gone to just over 1gn above book max no compression at all and I reckon there might even be room to go higher again but will see what the ladder results show.

And let's face it I do love to tutu.....;)
You certainly won't be disappointed with 2208, it is very good in the 7 mil o latté :D
I'm using it with 162 ELD-M s in mine and they are going very well. Haven't shot an animal with them yet but very accurate.
Attachment 173700
Four good shots and I got excited hence the one on the far right ha ha.
Always loved the eldms just unobtainable like a lot of things or rediculous prices on any that are.....what speed you getting ?Quote:

I'm also messing around with some 120 VMAX at the moment, I'll be smashing some large grass fed hare in a week or so, and hopefully a sneaky sambar or two.
Are they mag fit loads, or seated out?Quote:

I have results.....just having late lunch then I'll put up a post, safe to say I'm well pleased :cool: 2208 is a go for this rifle
Nice looking forward to hearing your resultsQuote:

The 42.5gn load at this point was by far the best so I loaded up 3 more of them to check consistency then continued up the ladder in .5gn steps, this is why there are 6 lots of velocity for the 42.5gn load
Attachment 173734
Sorry about getting sideways pic ....stupid phone :pissed off:
You'll note I have only done average speeds and es values for some loads, these were the loads that produced the best groups that I felt were worth investigating.
The lower end of the charge ladder pretty much all shot the same or close to it, groups didn't start to tighten up till I hit 42.5gn
The es through most loads is pretty good which I put down to my prep and consistent approach to loading....in theory you can tune any load with seating depth but I chose a load that had a good es and decent velocity.
Strangely enough the hottest load shot a very poor group even though the es was only 12fps, I didn't use this load anyway as it was quite hot and reasonably compressed.
For now I've settled on 42.5gns
Which shot a best 3x shot group of .6" @2635fps with an es of 18fps
Here are the targets.
Total round count for load development 30 rounds which is not bad for a quick slap together load that shoots .6" groups :D
I could tutu further but I'm happy with how it's shooting and I don't have the time.
It's got more knock down than factory ammo and lower es so should be good out to my max limit.
Anyway here are my target pics.

I decided on the 42.5gn load for a few reasons, it shot very well, it was not compressed and it was nowhere near as hot as the next best load which I figured is a good safety precaution.
At no stage did I get any real pressure signs even well above book max but I see no.point in loading up to absolute max when it's just not needed, all that will achieve is shortened barrel life and risk of pressure spikes in warmer weather.
Here's the streelok data for the load
Attachment 173739
I haven't gained a heap of velocity by using 2208 instead of 2209 but I have achieved what I set out to do, which was to gain a little more velocity with less powder and a load that is not compressed.
I'm pretty pleased with the results, for what was for me a very quick slap dash load developement.
The biggest limiting factory for this load was the mag length however it didn't stop me finding a great sub moa load with the awesome 150gn eldx.
Hopefully take some beasties with it soon.
Good ShitQuote:

Very tidy!
Really satisfying.

Just out of curiosity, what velocity did you get with the factory precision hunter?
Already deleted the data off my strelok but from memory about 2500fps.Quote:

Interesting comparison with my mates 15" 308 today he's shooting 155gn amax with a mv of 2700fps
The bc on the 150gn eldx us substantially better and the 708 has more velocity and ft/lbs at 500 yards than the 308 even though the 708 has a lower mv
Not that it matters at all just interestingQuote:

At extended range BC is fairly significant for retaining energy . Obviously need a balance it with velocity to allow the projectile to expand and do it job. Should have a bloody good load there mate!
I'm certainly very pleased with the resultsQuote:

I've been using the factory Precision Hunter ammo and have found the projectile extremely good on animals from 30 yards to 300. The velocity averages around 2650fps but has quite a wide spread with as high as 2680fps and low as 2624fps within 10 rounds. I have a suspicion it became less consistent when they changed from the regular silver primers they had to brass ones (only on 7mm08 rounds, everything else still gets the silver primers).
Does anyone recommend a good range for an initial ladder test? Looking at the hornady reloading page, depending whether you count 2208 as vargant or imr4064 (the two comparisons adi make on their comparisons table) it changes the max load by 1.7 grains...
and on hodgdon's and ADI's website it has a great varience for 150gr projectiles between sierra or barnes, no eldx.
Should I be looking at the data for 154gr hornady sp instead as on Hornady's website it has them in the same group. Fairly new to reloading so taking it easy but hoping to find a load with decent accuracy around 2700+fps which seems doable from what other people are getting.
Cheers
I've just worked up a load with 2208 and 150 eldx in two different Tikka .7-08 and ended up with the same load 40.2 grains I think I'll check tomorrow if you like. If I go much higher the bolt lift is a bit hard and some stamping. Speed was 2675 fps and both shot very well.Quote:

Took the latte rifle out for a walk this weekend and shot 2 fallow yearlings at 311 and 330 yards, both bang flops and the damage to the wee fallow front shoulders was brutal....I almost felt over gunned :DQuote:

Well done, enjoyed the zero to final blood read. What's your take on a 708 as a "one do all" rifle?
Liking it alot so far, definitely need to test on reds but I have no doubt it will preform equally well on them.Quote:

2-12 or 3-15 scope may be on the cards when funds allow.
Very light on the recoil even with what is considered a stout 150gn load, its a pleasure to shoot, not that recoil has ever bothered me.
I went back to a 3.5-10x40 vx3i from my 3.5-18x44 z5 on my 7mm08 to save some weight and just think its united better. Haven't missed the extra zoom much.Quote:

Didn't feel that it was unreasonably small in the scope. I do feel the 10x is plenty for any reasonable shot (way less than this shot but once an animals injured like this one figured it was better for me with a decent drop chart to shot rather than old mate and his kentucky windage just scaring it over the ridge wounded. I'd definitely weigh up whether the extra size and weight of a bigger scope is worth it. If you just want it then do it anyway that's why I've got another vx3i and z5 on the bench with no rifles just incase I want to play musical scopes again.
If you have a high power scope its really interesting what power you actually use the most. Ive got a 4-24 on one of mine ((.223). The top end is good for assessing heads and precision shooting of wallaby and deer good light - but I usually just wind the power for the best picture and shot without looking at the setting. For shots like yours at those Fallow Ive noticed after the shot the power has been between 12-18 almost every time.
I guess 12-18 gives me optimal clarity and view.
At dusk its useful to be able to go down to 4-6 too.
Yup I'm not in a hurry, I've had big long range scope before and that's certainly not what I'm after.
The 2.5-10×44 Monarch thats currently on it is a bloody good match.
Ideally if I could lay my hands on a 2-12 that would be all I ever needed but most scopes in that mag range are worth unicorn turds.
I had a Monarch 3-12×44 that would've been perfect that I foolishly let go with a rifle I sold :oh noes:
I do like the idea of being able to crank the mag right down in low light or bush ranges and definitely want to keep the weight down.
In reality probably need to look at a few more animals through this scope before commiting funds.....but hey it's nice to dream.
