Just finished reading Bryan's new article in the March issue of PS on the BC of the Berger 155 Palma bullet, and wanted to complement him on the way he explained some of the reasons for inaccuracies in the advertised BCs of bullets. He explained the reasons for the differences in predicted BC of a bullet due to the use of G1 form vs. G7 forms in such a way that even an old farmer like myself could understand it - now that's an accomplishment in itself! He also made up a table to show the effects of meplat uniforming vs. meplat pointing on this particular bullet - good stuff, Bryan!

Only downside is that reading the article has created a desire for an exterior ballistics program that offers the function of using various form factors to calculate trajectories. How does Art Pejsa's program do in this regard?
 
Thank you

Thanks for the compliment. I've been working on the BC testing for a long time, and it's very rewarding to see it in print. It's especially rewarding to know that it's understand-able:D

Bryan,

I read your article last night... good stuff! I'm very much looking forward to your future articles on other 155gr bullets - wish we didn't have to wait, but I imagine Dave Brennan might object ;)

Besides RSI Shooting Lab and JBM, what other programs out there do G7 BCs?

Good work,

Monte
 
Thanks Monte:)

Patagonia Ballistics offers the option of multiple standards.

I'm working on a ballistics program for distribution, but it's going to be a while before it's ready for prime time.
