Got the 264 out today to start the break in and start getting some dope figured out. Right out the gate it was less than moa and this is a 300 yard group on the tail end of the first 20. Factory Hornady 123 Amax was averaging just shy of 2500 from my 22" rifle gas barrel.

Looks like a shooter for sure. At 300 that group is WAAAAAY below MOA!!!!!!

With my old eyes I'm looking at about a 0.477 MOA going on 1.5" CTC on that group. Excellent shooting. I guess that one won't be a tomato stake anytime soon.

It's a bit over 1/2 moa. The 300 yard group is right about 1 3/4".This 100 yard group is about 5/8" center to center. Probably keep it around for a while. Would normally shoot 5 shot groups but my 5 round mags only hold 4 and the 4th is tight. Need to clip some springs.

I own calipers, use them for loading ammo. Don't usually break them out to measure groups. A tape seems plenty accurate enough for me.

That helps. You gotta go digital (21'st Century, so this old man won't have to do the math..LOL Do the 300 yarder and post your readings outside to outside. please.

"Outside" to "inside" works for all calibers.

"Outside" to "inside" works for all calibers. Yeah but dividing that number by 1.047 is tough. LOL That one was 0.56 MOA at 100. The 300 yarder was 0.571. I just tare the mic with the bullet diameter to save one step. Greg

Yeah, but you don't have to subtract the bullet diameter, THEN divide. Any way you figure it, damn fine groups. I wonder how it will hold up for seven shots.

I'll be sure to post up when I finish the break in and shoot some groups with more rounds. I was adjusting gas block, shooting 3 then clean barrel break in, playing with a Magneto speed, and helping others at the range that were struggling (who knew the thumb screws on a cantilever scope mount wouldn't work when finger tight, LOL). Those were the only 2 groups I shot where I had cleaned, shot 3, then shot a group, then clean again. I was just impatient and wanted to see how she was doing.

Maybe I'm confused... But if you measure the outside edges of two holes and subtract the diameter of a bullet, or measure the inside edges of two holes and add a bullet's diameter to get the CTC... wouldn't it just be easier to measure the two left edges of the holes, using the example photos shown, to get the CTC without the math? Try it... measure the two same-side edges, then move the calipers over the center of holes. Am I mistaken?
