MR762/MR308 Precision Shooting - Show Your Groups?

[HKSniper11B]

What has been your experience with the H&K Rifles, and what kind of accuracy and distance are you getting with them?

I wished to start a thread showcasing various distances and precision of the Heckler & Koch MR762 (US) and MR308 (Europe) or, if possible, those who have access the M110A1 CSASS/SDMR. I have about a year on this platform, and have worked hard testing factory loads. I have an extensive writeup on this platform on HKPro HERE but, I wish to focus specifically other's extensive expertise of precision and long distance shooters here.

For those who respond with their own shot groups, please share the following:
1) Which Rifle? (MR762, MR308, M110A1, G28, G27)
2) What Barrel Profile? (Barrel Length, Heavy or Medium Contour)
3) What round used?

Included are some of my best groupings. Both rifles I run are Heavy Contour 1:11 Twist 16.5" Barrels. DOPE is as identical as they can get with the two. For the tightest groups, they seem to love the Hornady TAP ELD AR 168gr. Running the Federal Berger 185gr Juggernaut has been a laser beam out to distance. I plan on reporting more as I train and compete more with these two.

I rarely post, but I hope I can be more active here as I get out and shoot more. Thanks for indulging me.

 

[Near miss]

Have shot MR762 A1 plenty of times.
Have seen them shot by skilled shooters with incredible precision AND accuracy.
Mostly fed with scenars, 168 or 175.

Sierra 168s from PMC worked also miraculously. 308 bulk ammo is what it is but it certainly is not bad with them and they are very lot dependent.

Here's to hoping others show what they have and what they've accomplished.

I've "heard" from many what they can and cannot do with this rifle, along with how good, or how horrible, it is. I've heard incredibly horrible reviews on the M110A1 CSASS from B4 qualified Army Snipers, as well. While I have my own year of experience behind the trigger, and I consider it quite capable from my own imperical data, it is my hope to see for myself with shotgroups and grouping data/measurements from others.

I have zero experience with Lapua rounds. Sounds like I'll have to try it out and see what I kind of groups I can get. I appreciate your input.

I'll work on adding some groups to this as I am able

Been a while. No updates from anyone?

[Near miss]

One 417 A1 started shooting wild. Mostly 2-3 rounds within moa and then one or two could be 2 moa away.
It turned out its front pin had cracked. Apparently the A1 model's pins that are opened by sticking a bullet in (or the key contained in the stock) are not strong enough.

The rifle has a lot of training done (I am guessing a bit of use-abuse) with and 20kish rounds through.

New pin was easily ordered from Germany.
