I just started loading for 7mm-08. 20.5 inch 1/9 twist Shilen Barrel. It shoots lights out with 162 A-Max with IMR 4064 powder. It will not shoot the 120 gr V-max with that powder. Since I only have a Speer #13 Manual I was going to try two powders I had on hand - H4350 and IMR4350, before I bought something else to try. Well the IMR4350 had load data that was up to 52 grains, where the H4350 had 50.0 max compressed. The IMR4350 load was top of case at 50.1 grains. I e-mailed Speer and said it was right. No way it's going to fit. Of course they say it's not designed for V-max bullets. Anyone have V-max data for these powders with min/max data. If those powders are not appropriate or group well what others do you suggest with some min/max data - maybe Varget. Thanks.

from the hornady manual 7th edition
varget powder rem 9 1/2 primer 120 gr v-max, oal 2.7"
minimum 34.7gr @ 2500 fps
maximum 43.7gr @ 3000 fps
rl-15 36.3 at 2500 to 43.7 at 3000 fps
win 760 39.5 at 2500 to 49.7 at 3000 fps

the only 4350 for the 120 is accurate arms aa4350 at 42.6 at 2500 to 46.6 at 2800 fps.
you can try h-4895 at 32.8 at 2500 to 41.8 at 3000

the a-max bullet is a target bullet and is not designed for hunting use.
and the v-max is a varmint bullet.
for deer hunting i would recommend and use their 139 gr interlock.

Did you try using a long drop tube when filling the cases? They help out a lot when you are loading compressed loads.
