223/556 powders
Hello again, I've got some questions reguarding powders for the 223/556. I've been using BLC2 and IMR 4895 with some good results in my 16” AR chambered in 556 with 1-9 twist, using 52gr to 62gr bullets. Im working on a new build that will have a PSA 20” 1-7 twist. So whith that I have been thinking about a load for 20” vs 16”. The 20” should yeald higher volicitys correct? This should have nothing to do with the chamber pressure, just longer barrel time / burn time? I read some where that blc2 can cause barrel ringing in longer barrels?
Compatible powders I have on hand:
BLC2
IMR 4895
IMR 4064
CFE 223, havent tried this one yet
Thoughts?
