The Lee 200 grain SWC mold is a rounded nosed bullet that even fed in one of my 1911s (wouldn't feed much, but ball). Of course, the P90 will feed anything without chokin', or at least I haven't found anything that will choke it, but this bullet is quite accurate, what I used on the target to the right, and makes a great practice load in front of 5 grains of bullseye. I shoot it for about everything from competition to field carry, though my self defense load is the old "flying ashtray" Speer with a healthy charge of Unique. I have a small stash of those bullets, don't shoot 'em, 'cause they're no longer available. But, the 200 grain Speer gold dot is available, just haven't tried it, yet.
I also have a +P handload I worked up for that 200 grain SWC to carry when I used to hunt hogs with a guy using dogs. We killed 'em with a knife, but I always carried the P90 just in case and wanted something with some punch. That load puts up a little over 500 ft lbs. I have better guns for that (.45 colt Blackhawk) now days, but haven't hunted hogs with dogs in years, but that load makes a pretty decent outdoor round for the gun. It's the 200 grain SWC behind 12 grains of blue dot. It has some kick to it, but the P90 is a tough enough gun to handle it. I do have a 16 lb 1911 spring in the gun which handles every load I feed it and reduces any slide battering from the hot stuff.
