    45 colt / Unique, estimated velocity?

    Just gotten my hands into loading the 45 colt. I do not own a chronograph. Can someone help me out by giving me a ballpark estimate of the velocity of these 45 colt loads?

    Ruger "old" Vaquero. 4 5/8" barrel.

    1) 200gr FP, 8.0gr Unique.

    2) 235gr SWC, 8.5gr Unique.

    3) 255gr FP, 8.5gr Unique.

    Thanks!

    dan is right about that on the 200 gr and less on the others G.D.

    I'd estimate closer to 800fps on the 200gr load. I've loaded a Lee 200gr RF to the crimp groove over 8.5gr of Unique and got an avg of 836fps out of a 5.5" Blackhawk. With less powder and less barrel, I'd expect less velocity. Of course, your experience might be different.

    No idea on the other two loads. I went to titegroup and the 200gr was the only thing that had unique under it.
