tswisher21 Posted August 5, 2017 Share Posted August 5, 2017 Good morning Has anyone chronographed the exact same load but with plated and then Hi Tech coated bullets? I just started loading the coated bullets .they shoot well,but i was wondering if the load data would be the same. Any one to this? Thanks Tim Link to comment Share on other sites More sharing options...
StuckinMS Posted August 5, 2017 Share Posted August 5, 2017 Yes. I loaded xtreme and bbi 180 to to same 1.200 with 6.7grains of hs-6 and the bbi were an average of 62 fps faster in the chrono. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted August 6, 2017 Share Posted August 6, 2017 (edited) Coated will pick up some velocity over plated in most cases, so you'll be able to drop your powder charge .1 to .2 ... but you aren't magically loading unsafely, and you will certainly continue to make power factor. If your load was 4.0gr of some powder before, I'd load up some 3.8 and 3.9 gr rounds next time I had a chance to chronograph them.
