The best 10-shot group with the Mk12 has been 1.25" at 100 yards. That's with the same load of 77gr TMK's.

For a mid-weight carbine, that's not bad at all. Had I stuck to a 5 shot group it might be 3/4" or less.

I plan to keep working with it as I suspect it will do better, much of it a matter of my technique. I changed out the cute DD stock and installed a Magpul STR. It has about 200 shots through it and the nitrided 1 in 7" barrel may still be breaking in. Some further load tuning is indicated as well.

If TMK's actually will expend on game, the 1 in 7" barrel would be the place to shoot them. I got a doe with it last year, using 65gr SGK's, so I may use it again.
