    patterns

    I loaded some .45 Colts for my '73 Uberti copy with 777 2f. I loaded by weight which worked out to 26 grains which with a thin card allowed for slight compression. The range session gave me huge groups/patterns. Groups shot with smokeless AA#5 and pyrojunk were never over 2" @50yds. I think I was good on the amount of 777. Am I missing something?

    Hello salvadore,

    You didn't say which bullet your using.
    The Triple Seven load date says,
    200gr Bullet - 35gr-2F
    250gr Bullet - 30gr 2F
    I've never shot this in a cartridge, maybe you need a little compression on it.

    what bullet lube? 777 still needs BP style lube. Hard crayon lube will cause patterns.

    I use DAR formula lube, pretty soft stuff. Lyman's 454190, commercial thin card between bullet and powder. The powder is compressed moderately, no keyholing.... I don't know.
