    Well after some struggle to figure out why my BCM mk12 wasn't holding groups, i finally figured out my scope rings were loose. Anyway shot 18 shots through the chrono today and only had two errors. Stats are as follows.

    Ammunition: SWA Run N Gun 77gr SMKs
    Distance: 100yds
    Rifle: BCM MK12 MOD 1 18" bbl
    Temperature: 57F

    Avg: 2687fps

    SD:35.8 ES:154

    I'm not sure if that's good for a gas gun or not, my bolt gun's loads have a SD of 4.5 and ES of 11. Group to the left is mine to the right my friends.

    That would have been pretty good except for that one round dropped down in the 2500's.

    Still good though for the price and match bullet. I'd like to stock up on some of it.

    Thought about it when i got home SD and ES would probably look a lot better if i threw the oddball out. I mean honestly that one shot was a tad bit weird. Every single shot was above 2600 and then that one. Going to re average and see what it looks like with out that one.

    Throwing the low one out gives me this.
