My BCM 1/8 loves 68 grn BH match and Hornady 75 grn match . On Friday I was getting 5 shot groups that were in the 1/4 range . Black Hills shot the best and this was with 15mph winds. What are you guys getting ?

We can all guess but BCM won't say.

Never shot the two I have bagged, but using the Harris consistent 0.5" to 0.75" with my scope on 10x-12x. M4QUADRAIL

Not a 1/4 in.  Maybe .6 or so.
Esp not with a 15mph wind.

1.5".  Certainly nothing spectacular, but with 75gr PPU HPBT ($.35 rounds) that's pretty respectable in my book.

Sorry, I'm not a believer

Both the Govt. MK12 Mod 1's I temporarily had in my possession shot around 1 MOA with AA53.

I've never seen any of the Govt. MK's shoot better than that with 5.56 pressured ammo.

I have seen a 5 round group here and there less than that,  but not consistent accuracy.

My DD 16" Recce with a Lothar Walther LW50 1in7 will produced 0.5" groups at 100 yards with match ammo, also 1.1" groups at 200 yards with a 5 power scope, both 5 and 10 shot groups.
My BCM 18" SPR with a BCM SS410 Ion Bond 1in8 will produced 0.5" groups at 100 yards with commercial Fed 55gr and 0.9" groups at 200 yards with the same ammo and a 14 power scope.

I think there is very little difference between the accuracy of the 16" LW50 and the 18" BCM SS410, it appears that the 18" is a little more forgiving of ammo type, and the 14 power allows me to hold much better at 200yards than the 5 power.

DD Recce 16" LW50 1.5-5 Leupold


Here are 10 rounds at 100yards out of the DD 16" and this is Black Hills blue box... the square is 1 inch


5 rounds of Federal Gold Medal Match at 100 yards 4 power IOR scope.


My wife even shot a sub MOA group at 100 the first time behind a scoped rifle.



BCM SPR 18" SS410 4.5-14 Leupold


I never thought to take a photo of the 200yd groups with Fed 55gr FMJBT that measured less than an inch, I will next time though.

I usually get 15/64 groups with mine with 34kt gusts

Honestly the best I ever got out of my 1:8 LW50 is .67. It was shooting 77gr smk's

ETA: spelling

My build isn't a Mk anything, but it has an 18" barrel.  My groups probably average in the .8" range, maybe smaller, although I'm shot more than a few that were sub 1/2MOA.  I guess it's hard to compare group sizes, since not everyone does it the same.  For me, no matter what I'm running or what barrel I'm using, a 77gr SMK over 24gr of either Varget or RL15 with a benchrest primer will get me solid sub MOA groups.  I do need to do some work past 100 yards.  I very rarely get to do it and when I do, I don't waste my time shooting at paper.  I'll try to remember to the next time.  I believe I'm going to have access to 300 yards in the next month.  My personal best was around 1.1" for 20 rounds shot in under two minutes.
