[QUOTE="imartin, post: 2541167, member: 106328"] Got out yesterday. Chrono was giving my fits reading shots so I missed out on most data. However, when it did read, the readings seemed accurate based on expectations and other guns I was shooting. I ran a powder ladder from 40-50 gr of lil gun, 1 shot each, 1 full gr increment increases. This is a much larger increment than I would normally use, but bc pressure was in the 30K's to start I didn't want to blow through $200 worth of bullets to find the velocity I wanted. All in all really enjoyed shooting my B14 HMR with the SiCo break on it. The mag that bergara sent with my rifle doesn't feed 450 bushmaster and falls out with the higher velocity charges. So will be looking for a new mag. I did not experience any symptoms related to high pressure. Bolt lift was easy, no extractor marks, primers looked the same from 1 to 10. Last shot clocked 2855 fps @ 50 grs lil' gun. And landed next to the 49 gr load. This is where I wanted to be, probably will not waste resources exploring much higher. Will load groups up in this range and go from there. 221 gr at 2,850 fps is going to crush anything I hit with it. Gun has 14 shots on it after 1st trip out. A little early to do load development but wanted to get an idea, do some more shooting this summer, and fine tune in early fall. Will keep you all posted on my progress if you're interested.
