I am about to order a new rifle from PVA and can't decide on a final chambering. I know this has been discussed before and I have read the threads but I am considering 6x47L, 6 dasher, and 6 CM. I plan on using mausingfield SA, 26" 1:7.7 bartlein barrel, manners mini chassis with either AW or ARC mags. I plan to shoot either 105 hybrids, 108 ELD-M, or 110 SMK in lapua brass (no turning). My pros/cons I am most concerned about are malfunctions in loading and barrel life. I feel all are accurate and capable cartridges with the dasher considered "most accurate" of the 3 but I don't want to just be frustrated all the time if I can't get it to run well. With PVA dasher mag kits does this solve the feeding issue? I saw his video on his dasher feeding well. I will use it mostly for steel out to 1200 and some local club PRS matches. Help me decide which way to go so I can stop thinking about it and get my order in.
