Im wondering what your opinion would be on the optimal barrel length? After limited searching on the net, most ive found preferred around 22 inches but that was mainly on compact rifles. I was thinking 25-26 inch for mine? Would the longer barrel allow me to use a tad slower powder than usual for a bit more performance?
I hope I made sense. Thanks for your help.
The 7/08 has limited powder capacity and works well with 18" to 24".
The most jump in velocity per inch seems to be between 20' and 22" the 24 inch barrel
will only net you 20 to 50 ft/sec over the 22" and a 26" around 60 ft/sec over the 22''
I have a 20" barrel on mine and my best load is 3010 ft/sec with a 120 gr bullet,and with
a max load I can still get 3000 ft/sec using a 140 gr bullet,
I have also built several 7/08s with 22 and 23" barrels and they run 3050 ft/sec avg.
with the same 120gr load.
After 23" the increase in velocity per inch drops of fast .hence the reason most 7/08s
have short barrels.
I don't use bullets heaver than 140gr in the 7/08s so with big bullets a few more inches
might help but not much.
