[QUOTE="Broz, post: 952605, member: 7503"] Chris you got any BC figures on that past 1000? Typically from what I know the Matrix tends to trail the Bergers a bit. As far as the calibers I have worked with extensively up to 338's, we need to keep an open mind to a 230 Berger wth a field tested G1 BC of .743. They will run 3200 in a RUM with RL33 and in a 30-338 Lapua AI upwards of 3400. To get a 195 gr 7 with a BC of even close to .8 over 3500 and hold together will be a task, and barrel life will suffer dramatically. That was what we ran into with the 7-338 Lapua. So you wind up with that gawd awful fact of diminishing returns staring you in the face again. Then the 30 become a little longer life and very hard to beat and the 338 with a .819 G1 BC at 3200 is making them all hustle to catch up. That's where I am at now. It has the best barrel life of all 3 by quite a margin. Spotting impacts of them all on a rock at a mile plus will make you tip your hat to a 300 gr .338. At 2500 yards good luck even seeing the impact of a 7. Thanks Jeff [/QUOTE]
