Some LRH owners have reported issues but the fix appears to be relatively easy. The NFPJ adapter is a little too tight in some LRH bolt assemblies.
If you have a 45cal, give it a try in that one first. So far that one is my favorite with BH209. I have even used T7 primers with 100% ignition but only in 50F or warmer weather. I havent had a chance to try it in the colder temps.
Groups sweet too.
BIG 45 conical
And 180gr XTPs
Even loose fitting 300gr Powerbelts
My Extreme 50 is the cleanest IMO but only by a small amount.
