[QUOTE="Jud96, post: 1891432, member: 69478"] Another thing I’d like to add after looking at your groups some more, if you look at your groups from 57.0-58.0 I see a trend of two shots touching and one flyer. In my experience, if everything else is working and right, this points me to seating depth like I mentioned earlier. The rifle shows potential with the 56.0 grain load. When you take the Magnetospeed off, you could have completely different results though. I’d run like 57.7gr and then do a seating depth test. Depending on how much room you have in your magazine, will depend where you should load your longest rounds. I typically will start about .020 off the lands and work backwards in .010 increments. What you have shows potential, so you could simply seat your bullets deeper or closer in .003-.005 increments until the flyer comes in and the groups shrink. You could also do a wide seating depth test to find the most forgiving seating depth node. This will find a window from say .040-.060 off that has the same point of impact and groups are good. You might not get 1/4” groups with this seat length, but you’ll get good results and you will have a consistent and forgiving load you don’t have to tweak every 50-100 rounds. There’s many ways to tune your load and rifle, you just have to find what you like or what works for you. [/QUOTE]
