I am confused on 308 Win vs 30-06 Sprng. Can someone tell me how 48gr of 4064 in a .308, and 52gr of 4064 in 30-06 using same bullet, show close to identical velocities? At least in the Nosler Reloading Data?
Went thru same thing, was using suppressor, found out i got bad barrel threading job, bullet was striking suppressor end cap so slightly it hard to see
Can anyone tell me what is going on? I am shooting older Sako AV in 300 Wby. Saw where IMR 7828 max. load was 84.5 with 180 gr. bullet in Nosler load data. I loaded group of 3 each starting at 82. and going up to max of 84.5. When i shot 83.+ at range, pressures were so high i couldnt open...
