[QUOTE="MAX, post: 23125, member: 184"] God bless long barrels! As mentioned above you always have the option of cutting it down if deemed appropriate. Advantage gain? How 'bout a 7X57 AI with a 28" Lilja tube that matches the 7mm Rem Mag with 54 gr. of RX19, bullet for bullet. Another aspect relating to accuracy w/large capacity/small bore/slow powder combos is exit pressure. Short tubes w/ above mentioned circumstances(7 STW for EX) can generate bullet exit pressures in excess of 20kpsi. A) that's wasted velocity, B) it has a rude impact on accuracy. C) what's the point of a slow powder if you're not going to use it? Long is GOOD! [img]images/icons/grin.gif[/img] [/QUOTE]
