[QUOTE="Fiftydriver, post: 430129, member: 10"] The A-Max bullets have a very similiar velocity limit as the Bergers. In most cases, if a rifle likes Berger bullets, it will also shoot A-Max bullets very well, that is IN MOST CASES. Nothing is written in stone. To the other end, if a rifle does not like the Berger, it often does not like the A-Max either. The SMKs have a much thicker jacket then either of these other two match bullets and that is why on average, it will shoot acceptably well out of most rifles and chamberings, even high velocity ones with good accuracy. I have not found the velocity ceiling of the SMK bullets in approriate for bullet twist rates and believe me, I have TRIED VERY HARD!!! I have driven the 107 gr 6mm SMK to +3600 fps with fine accuracy, same with the 142 gr 6.5mm SMK at 3550 fps, the 175 gr 7mm SMK at 3600 fps and the 210 gr SMK at +3450 fps. I have yet to see a SMK dust except for some 80 gr 22 cals that were shot out of a Lilja 3 groove barrel chambered in 22-6mm AI going well over 3550 fps. In this case, they were simply over spun and the 22 cal SMK jackets are thinner then the others. [/QUOTE]
