Xtreme 124HP (9mm) using Alliant BE-86

[MarkDisciplinare]

I've not loaded up any of the new(er) 124gr MPR rounds yet, but I'll PM you some info. from others that have done that with an XD9.

For my 124gr RN loads, I'm running them around 1.13.

Your 5.3gr may be a bit hot when the OAL is only 1.06, that's a bit deep so the pressure will increase... Check your Inbox.

After looking at that post you're 100% correct as my XD9 has the short leade as well. It was interesting that my accuracy node range with the 124gn RMR was also 4.9 to 5.1 gns of BE-86. The best group so far is 5/8" at 25' with 5.0 gn.

Small 9mm cartridges build up pressure quick so thanks for the heads-up.
