[QUOTE="Pdvdh, post: 1082637, member: 4191"] I don't use JBM, but I'd be surprised if you couldn't enter any BC value you desire into that online ballistics program. I haven't done extensive testing with my meplat trimmed and countersunk Bergers - either extensive long range measured drops or chronographed velocity @ long range. I collected 1000yd chronographed velocity for the .308 Berger 210 VLDs and the .284 Berger 168gr VLDs prior to meplat uniforming, but not after. That's a pretty time consuming chore for me. I don't have the type of downrange velocity measuring equipment Bryan Litz uses - which makes this chore much simpler. I shot the meplat uniformed bullets at 1000yd and did notice the bullets hitting a little lower. I don't provide info. on this Forum unless I'm confident in the data, and I simply haven't tested sufficiently to provide a % reduction based on my personal measurements. I reported the range of BC reduction I've read on the Forums - and I read and collect a lot of armchair knowledge. I've shot my meplat trimmed bullets at 1000yds and tweaked the BC value down slightly in my ballistics program to match my measured drops. I use ColdBore 1.0 ballistics program. I've played with JBM a little years ago, and I'm virtually certain that their online program can be fed any BC value you desire. [/QUOTE]
