[QUOTE="backwoods83, post: 893472, member: 29890"] I'm done arguing anyway Brent, plus I don't even have a computer, I asked a simple question to a PROFESSIONAL that still hasn't been answered, but anyway back to the question at hand. In testing the bc of the 130 Berger can be raised from .552 to .579-.581 with a Whidden bullet pointing die, getting it close to the bc of .612 of the 140 Berger, but same goes for the 140s they come up to .639 give or take .001 when they are pointed, the biggest issue is with .188" freebore its harder to get close or in the lands with a 130 and still have sufficient bearing surface in the case neck. If you can find 130grn Norma Diamondline pills they are a good compromise, they have a slightly longer bearing surface than Bergers and they aren't as finicky, and when pointed there bc falls at around .598. Just be careful pushing any of these three bullets over 3250 in a true 8 twist, as I have had issues with them not wanting to go to sleep until 200yrds or more and on a few occasions I have had jacket/core distortion at those velocitys.
