    After checking out the BFR today ... ran some tests on MagTech .44 mag ammo and also UMC .45acp. I had found when trying the Rohrbaugh R9S recently that the UMC 9mm was diabolical!! Having got some in .45 decided to check it out to see if it was worth a light!. No SD - too lazy to do the calc's ... Chrony printer batteries died, and no spares .. duh!

    Put ten rounds thru para P12-45 (3 1/2" tube) and 12 rnds thru M625-6 (5" tube). Here are results - (25 yds target) .....


    Ammo type ........ Remington UMC .45 acp 230 grn FMJ

    (dropped decimal point - rounded figures)

    Shot # 1 - 733 fps
    Shot # 2 - 760 fps
    Shot # 3 - 763 fps
    Shot # 4 - 763 fps
    Shot # 5 - 741 fps
    Shot # 6 - 744 fps
    Shot # 7 - 757 fps
    Shot # 8 - 764 fps
    Shot # 9 - 769 fps
    Shot # 10 -746 fps

    Low vel = 733 fps
    Hi vel = 769 fps
    Average vel = 754 fps
    Hi-Lo extreme spread = 36 fps
    Muzzle energy (based on average vel) = 290 ft lbs

    (Interest comment ---- the Golden Saber 9mm, out of R9S came up with ME of 275 ft lbs ..... and from shorter tube! So, even if the .45UMC down on power, compared to other brands of .45, still strikes me as interesting near parity!)

    And here, the 12 rounds thru M625-6 .......


    Ammo type ........ Remington UMC .45 acp 230 grn FMJ

    (dropped decimal point - rounded figures)

    Shot # 1 - 860 fps
    Shot # 2 - 839 fps
    Shot # 3 - 850 fps
    Shot # 4 - 830 fps
    Shot # 5 - 821 fps
    Shot # 6 - 839 fps
    Shot # 7 - 816 fps
    Shot # 8 - 833 fps
    Shot # 9 - 836 fps
    Shot # 10 -831 fps
    Shot # 11 -815 fps
    Shot # 12 -827 fps

    Low vel = 815 fps
    Hi vel = 860 fps
    Average vel = 833 fps
    Hi-Lo extreme spread = 45 fps
    Muzzle energy (based on average vel) = 354 ft lbs

    Quite a useful increase in ME out of the revo!

    Actually shot off another 18 rounds (just too much fun!) ... results I think held pretty close. Final 6 I put on the splatter target below ..... the shot to left was my ineptitude ... called it there too - other five not so bad. One prob with the big black target and backlight - you tend to lose sight picture. Sights took a lot of adjustment - (first outing and danged if I know how previous owner had hit anything they were so far out) .. but another small tweak next time and they'll be fine. Time was beating me.
