Based on my Outkast CLR when that M28 comes out in 7PRC it will be one sweet shootin', 6 lb badass. And, I'm guessing with the bottom metal it'll hold three down.

Hopefully you get more than 3.34" in your mag-box. That's what the original 28 housed down below, had to go 32 to get a 3.7" box.

Might be 3.34 or maybe 3.4 - can't tell without pulling her apart which I don't want to do 'cause she's all sighted in for hunting season. Plenty of room for factory stuff which is my main concern. Here it is with the Federal ELD X load which is 3.187" - interestingly a tenth of an inch shorter than the Hornady loads:

Is it a 1/10" or 10 thou shorter? Looks pretty tight at 3.187

So, the Hornady 180 ELD M load is 3.288. Which seems like a big difference to me too, but there it is. This morning I took a 180 ELD M and stuck it in an unfired case, snug fit, and left it long, markered the bullet, and then closed the bolt on it. Which is how you guys figure OAL to kiss the lands from what I've read? When I extracted the cartridge it was 3.3835. It was a smidge too long for the mag box so, must be a 3.34 mag box.

So, if you want to experiment with kissing lands in a SAAMI chamber and 180 ELDMs, you're going to want more OAL in your mag box. For me the goal was factory ammo and, the 180 ELD M factory load has given me a bunch of 1/2 - 3/8 inch 3-shot groups.

.05 inches of cushion in the box is pretty tight. But, I have been shooting groups out of the mag and so far the accuracy has been outstanding.

I think you met your goal. I wouldn't complain.
