Optimal free bore
Posted: Sun Nov 17, 2019 1:11 pm
Hello to all,
I am a new member and I bought a ruger american go wild camo with a 22 "barrel.
I tested several bullets, 200 FTX, 250 FTX and 300 XPT with W296 powder and federal GM205M primers.
I have experience on many other calibers, I have reached the maximum precision with ammunition in which the bullet is close to the grooves of 1-1.5 mm.
How much do you keep the bullets from the grooves?
I verified that with 300 XPT it shoots well with a seated bullet 1 mm from the grooves, while with the 200-250 XPT I still haven't found the right compromise charge/OAL.
Thanks
