I know that I am not the first person to ever do this, but also was wondering how many members practice this method of flat pointing their round nose slugs. Everyone knows that the old ball slug used in the 45 acp, is very inefficient in making a good wound channel as a hunting bullet or self defense projectile. Quite a few years ago, I traded for some "heavier than normal" ball slugs. These particular cast ball slugs weigh in at a consistant 249 grains. They came unsized, with a single lube groove. The tip of the slug is radiused, but more pointed than the standard ball slug. So, wanting to keep the positive feeding ability of the ball slug, but also make the slug have a more desirable hunting or self defense projectile that would produce a better wound channel. I dug through my dies, and for the top flattening die, I used a Lee Universal belling/flairing die. There are a couple different size belling posts that can be rearranged to suit. The base of each is flat, and that's what I placed flat side down in the die to bump the slug into to make the flat point. For the push rod, I used a Lee .410 (that's the biggest I had) that goes with the .410 push through sizer die. After flattening a few of the round noses and getting the meplat that I wanted, the slugs measure as follows. The length of the original slug was .712. After making the flat point, the height is .612. These dimensions are +/- .002.
The meplat is .300. The slugs only bumped up to about .455 in diameter. After sizing to .452 and seating to 1.200 they make the plunk test just fine. When the weather warms up I'll give them a try. One other thing, in their original length of .712, the slugs had to be seated deep enough to fit the magazine. This raised pressures because the slug seated so deep. It'll be interesting to see how they feed in my PT-1911. I may load some up and try them in the Uberti SAA and my Winchester Trapper 45 Colt. Any thoughts on the subject?
