Tried it in my 300RUM. With 190gr Matchkings, and 215M primers. I had fireballs coming out the end of the muzzle. It was quite impressive. So impressive, I gathered a crowd watching the fire. The range officer stopped me and thought I was over pressure. But I showed him the cases and saw no pressure signs. It was cool, but different. Accuracy was good however. Just wonder if it was because I was not burning effieciently and the fire will go down with higher pressures. Thing is with this krieger barrel, seems to generate more pressure quicker.

Bigcountry I have been using it in my Sendero and haven' t noticed any flames. I started at 93 grs and went up 1 gr at a time and am at 101grs right now and am starting to show primer flatting. I am using Hornady 180SSTs. I have been getting decent groups but more flyers than I want. My Chrony is not working so I don' t know bullet speed yet. I have just bought a RCBS neck sizer die to try to improve. I think that I am seating at 3.665
