1MOA = 1.047" @ 100yds. Use that as your reference and divide/multiply 1.047" by the ratio of distance you shot at/100yds to get 1MOA at that distance.

100 yards, I'm not brave enough to joke about the distance hahah.

With out a chronograph how do I go about analyzing what the diffrent charges are doing. Or is it as simple as which group was tighter at a given charge?

Thanks for moving the thread!

I warmed up with normal fed match 7.62 and the p.o.i seemed alot closer to the bullseye. Thoughts?

Is that what you sighted in with? Different ammo will have different poi

Ed, in the pic of the group you posted, you're using the caliper to measure from furthest outside to furthest outside - you're adding extra stuff.  Measure center to center, furthest rounds apart.  That'll cut your number down, and when you divide, it'll give you the real group average.

Thank you brother I'll have to do that for the one on the first picture

Is this the proper way20141026_115842_zps88db978f.jpg

And with the flyer it measured 1.672

Also I had this happen with only my 7.62 fed cases so I didn't use them.

Idk if you can tell but the primer is not uniform20141026_120110_zps3c3e9d85.jpg nvm I need to buy a primer pocket uniformer lol

I use the RCBS handloading tool, and you can put the rod in there upside down - and it will do what you're seeing there.

 

Unfamiliar with what you're using, but that's worth checking out.  One side is tapered, one side is flat - you want the flat side seating your primers.

This essentially is what sits my primers once I bring the arm all the way back up. That piece of metal on the side of the ram
