Now this is just speculation, which I think is true, and it sort of confuses me, maybe I am missing something.
For sake of arguments lets assume full length bolt actions for maximum velocity.
People claim that 308 and 303 are ballistic equivalents of 3 full power rifle rounds from WW2, 30-06, 7.62 x 54 r and 8 mm Mauser. This rounds can easily push 150 grain bullet close to 3000 fps, and can be loaded to exceed it.
I have yet to see 308 ammo which comes close to 2900 fps, other than those magnum charge loads from buffalo bore, or whatever, with 150 grain, most are 2700-2800 range for max loads. Now 303 is even less, with 150 they generally get 2600-2700 fps.
30-30 and x39, with 150 grain get up to 2400 fps (30-30 could probs do even more), with 300 blackout at 2200 fps (this are from long barrel bolt).
So from the above, that full power push about 2950-3000, 308 is full power minus 150-200 fps, 303 British is minus another 100, and mid range 30-30 and x39 are minus another 200 fps from 303, with blackout yet another 200 fps slower.
So my question.... drum beat....
why is it that when comparing 30-30 and 308 or 303 its heaven and earth difference???
When comparing 30-30 with 300 black out, they are ballistic and energy twins
and 30-06 etc with 303 they are ballistic and energy twins?
Just trying to figure this out, is it just matter of opinion?
