[QUOTE="Eaglet, post: 368713, member: 3756"] Everyone is so excited waiting for the Berger 300gr. I decided to compare the 300 gr. SMK with the 300 Berger. I'm using G7 of 0.381 for the SMK and the designed G7 of 0.468 for the 300 Berger. Remember, this number is based on Berger's bullet design. [B]TRACK - 1[/B] = 300 gr. Sierra Match King (SMK) [B]TRACK - 2[/B] = 300 gr. Berger VLD At 5000 ft elevation, standard conditions for that elevation. Using Muzzle Velocities of 2800 ft/sec for both bullets. The SMK will remain supersonic up to 2020 yards. The Berger will remain supersonic up to 2480 yards. Assuming they both will open up at 1700 ft/sec, the SMK will have that velocity at [B]1185 yards [/B]and the Berger at[B] 1455 yards.[/B] Using a 10 mile/hr cross wind, at 1000 yards the VLD will be deflected 10" less than the SMK; and at 2500 yards the difference is a whopping 100 inches!!! Little over 8 feet. Numbers you see in red means the bullet is subsonic. [IMG]http://i49.tinypic.com/m7f0xf.jpg[/IMG] [/QUOTE]
