I picked this up today in 45 colt, 45acp. Four and 1/2 inch barrel. I'm not going to shoot any full house loads through it but thought I'd like to carry for something in 25 yard range with my rifle of course. I'm casting a Noe mold that's been sized to .454. After slugging this barrel I'm finding I'm running my bullets through a Lee 452 sizer and lubing on Lyman 454 lube sizer. Seems to be lubing ok. Bullets average 260 to 261 grains using wheel weights water quenched. Was what my rifle liked but it's gone now. Wonder if I should order another mold or just size these twice and go for it. .452 is .002 over my slug through the barrel. Was wondering what velocity to keep good ethical kills. I'm thinking 800-900 fps. I could be wrong. Going to use either Unique or HS6.
