My gas gun load development

[Burt Gummer]

Lever and CFE should be your go to powders. Somethings got to be going on if your barrel does not like those two.

2500 is a little on the slow side, generally somewhere around 2650 seems like a sweet spot for accuracy with the 6 ARC. I have tested reloads with no less than eight different rifles and most if not all liked Lever, CFE, BL-C2, H335. I have used other powders with mediocre success but the aforementioned worked very well.

Really no need to fireform your brass if you are converting Grendel brass. I have fireformed and not fireformed with little to no difference between the two methods.

   Iagree with everything you’re saying regarding LVR and CFE. It was quite the surprise for me when both of them could barely manage sub MOA. 

   I’m also new to reloading and think this may have something to do with my results. I’ve already caught myself not bumping the shoulder back enough and causing cycling issues. One or two other steps could use a little more consistency admittedly. There’s a good chance that I could see better results with them but at this time with the short supply of components I think I’m going to stick with the 748 since it’s easy enough for a rookie like myself to get good results with. I ran two ladder tests with both the 112 Barnes and 109 Bergers using LVR and the results didn’t seem to change by much. ??‍♂️
