Thread: 7mm08 loads 150 - 168gr

Beavis Iv done a couple of 7-08s with 162 amax, RL17 is pretty good for velocity and gave around the 2700 mark in 22-23 inch barrels. I would suggest staying away from the 160 accubond even the 140s struggle to reach speeds needed for good reliable expansion from a 708. I don't considder the barnes a long range bullet but Im a big fan when used light for cal and driven hard. The heavier with better BC thing is not relevant where they are concerned IMHO.

I found pressure quicker with accubonds than amaxes in my 7mm mag too, bearing surface and density etc perhaps mean its a bit tighter to squeeze down the tube so you may find velocity down on the amax, its what I found anyway

I am yet to try but will do when i run down my loaded ammo.
I am going for the 162 amax in my t3, Will get a long action bolt stop and mag and seat them right out.

Looking to use rl17 and shoot them around 2650

Re17 certainly gets velocities up but I got turned off it because of its variation in different temperatures and the early throat erosion I have seen in mates rifles. With 140s I managed to equal the Re17 speeds with 2208 in the end. Going to try in my 19" 7mm08 when I get a chance over thenext couple of weeks

Rl 17 seems to polarize people a little. It did seem to spike up when close to max and there are a few reports of premature errosion. I think if used sensibly its like most other powders but its tempting to crank it up and theres never a free lunch. I havn't used it enough to have an informed opinion on temp stability but RL powders in general seem to get a bad rep in that department.

Cheers guys changed my mind on Cal anyway

Ive been running the numbers too, for my sht barrel 19" gun the difference between amaxes and 140gr bts isnt all that muh (mind you I wasnt really thinking of its long range capability when I chopped it to 19") a 26" long throated , non suppressed 7mm08 would make a nver nice to carry and very capable setup while still being pleasant to shoot
nb Im stll confident taking game to 500m with the 19" setup

41 grains of AR 2208 behind a 162 AMAX gives me 2640 FPS out of my 19 inch barrelled, supressed model 700 7mm08. I tried Reloder 17 but at mag length the load was fairly compressed and accuracy was crap for similar velocity as the 2208 load, dunno what I'll do with the Reloder 17 now maybe it will work in my .243. I have always had good results with the ADI powders.

I have some loaded up, will chrony them when I can coordinate a day at the range during daylight....
Enthused to hear you are getting that much from yours

That was over my cheap chrony but when i shot it at 400 yards the drop worked out pretty much spot on.I was just playing really as i use my Rem Mag if i ever hunt in places where i might get a shot over 300 yards.The 3 shot group i fired at 400 yards over the bonnet of my Safari went just under 4 inchs which is not bad for a bush rifle that is standard apart from a trigger job and supressor and the AMAX's at mag length.

Its 130 thou jump if I seat mine to mag length
If I use the longer mag and seat it out to 10 thou it certainly gives more room for powder, these tikkas have a very long throat

Is it worth trying 2209?

Im running 23.something inch bbl. Might head up lake lyndon again on friday with some 2209 loads. If it can shoot accurate at max capacity, might be a better option than the 2208. Will do a load for the barnes 150 TTSX too.

Best thing about the 162 amax is they are a proven performer. Ive had bad results with 140 SST (270) and 208g amax, but the 162's have quite a following, especially at lower speeds (norway etc).

4 inches at 300 yards is mint. I bet you cant judge the wind that close anyway.

We are using a mild load of 2209 (44.5gr) with the 162 amax in my boys A-bolt and getting 2600. Got up to 2720 during load development but groups opened up and it was a heavily compressed load (wanted to keep it to mag length of 71.15mm) so the projectile is very deep in the case.
Not sure what the jump is but we are very happy with the accuracy we're getting - sub moa out to 600. Most groups running at 4 - 5 inches at that distance with the odd 1 around 3.
He's shot about a doz Reds with this load and so far none have needed a second shot which has made my 300wsm's backup role redundant

My OAL is 72.2mm so will be pretty close.

How many grains were compressed? You'd almost be compressed at 44.5?

Chris

Yeah it's slightly compressed at 44.5 (can hear a little crunching during seating) but if you used a drop tube it probably be ok.
