GeorgeMac Posted October 15, 2022 Report Share Posted October 15, 2022 Would any of you mind checking my data for Hornady Factory 108’s? I haven’t pulled a round to confirm length. (Playing with different ballistic apps and velocities to put together “rough draft” dope cards for the 12” and 14.5” barrels. If anyone has data on other 6mm rounds for 6ARC reloading feel free to post it in the thread for a reference Hornady 6mm 108gr ELDM Diameter: 0.243 Length: 1.2680 Weight: 108gr Drag G1/0.536 - G7/0.270 Quote Link to comment Share on other sites More sharing options...
shooterrex Posted October 15, 2022 Report Share Posted October 15, 2022 The factory 108 is averaging 2631 out of my 16" Wilson Combat barrel. Hornady's balastic app has the 6 ARC in it. Quote Link to comment Share on other sites More sharing options...

I have 900 projectiles for reloading (108 ELD-Ms), and I can measure a few. The length issue is easy to solve. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted October 16, 2022 Report Share Posted October 16, 2022 JBM Ballistics has two listings for the Hornady 108gr ELD-Ms - I'll measure some from my boxes tomorrow, and post them... https://www.jbmballistics.com/ballistics/lengths/lengths.shtml#Hornady 0.243 108.0 ELD M (Extremely Low Drag Match) 1.260 0.243 108.0 ELD M (Extremely Low Drag Match) 1.268 Quote Link to comment Share on other sites More sharing options...
GeorgeMac Posted October 17, 2022 Author Report Share Posted October 17, 2022 @98Z5V Thank you for confirming the bullet length of the 108's. That was the one data point on those rounds I was unsure of. @shooterrex Thanks for the 16" barrel velocity. It will be nice to have a spot to see what velocities people are getting with different barrel lengths, and projectiles. Quote Link to comment Share on other sites More sharing options...

Sorry sometimes I forget which gun I'm talking about. Quote Link to comment Share on other sites More sharing options...
