Thread: Difference for velocity and range - 20.4" vs 22.4" barrel - 7mm 08

Well thanks for that !
25 pages of no doubt erudite discussion and good photos.
Can you summarise any further than your initial post:

“Actual specific bullet function matters much, much more than the 3 digits stamped on the brass.
You cannot compare a 50-55gr basic SP (old .222 fodder) to a more modern heavy-for-calibre bullet that is tipped (or not) - the 73, 75, 80, 88gr ELDM, the 74 and 80 gr Targex, the various heavy Bergers, the 77gr TMK.
The wounds they create are totally different. The size and nature of wounds is what kills a deer.”


Can you suggest a better metric than kinetic energy ?
