So with a 1:10 twist the 308I would look up load data from hogdon and see what their pressures anfor all the powders they recommended in your 12tw barrel. Thats what they used but with a 24" barrel so keep that in mind. I used their data with the 208's and liked it but I am shooting a 10tw 28" barrel.

Send us an email to support@capstonepg.com and we will be glad to help you!I want to start developing a load for a bolt gun:
FN A5 SPR 20" 1:12 308 Win
CFE223
Berger 185 VLD's
New Lapua brass
CCI BR-2
New RCBS Competition Die
Just to make holes in paper from 100-600 and occasional 1,000.
Searched and searched, just can't find a lot data on this deal.
Mostly played with Varget, 175 SMK's and some 185 Bergers with mixed brass and standard reloading dies.
My first thoughts are OAL to be 2.810-? Does not need to feed from mag.
Powder starting at 44 work up to 46??
Any suggestions would be great.
I think 10 twist should be fine for all of the above.So with a 1:10 twist the 308
It would be more likely to shoot a 150 gr or a heavier 180 or 200 best ?
Son just bought a new carbon fiber barrel savage in 308 and wanted to develop him a 200 HD Whitetail load.
