For what its worth, I tested 452-374 sized 0.452 and seated to 1.272 (which is deep for that bullet, but necessary to fit the 1911 mag). I used 4.0 grains Titegroup the starting load from the Lyman Cast Bullet handbook. The Lyman load was for the 1.272" COL. One batch was traditional lube the other was Powder coated. My bullets have a BHN about 10 and the bullets tended to be swaged down some due to the deep seating. The lubed ones leaded my barrel but shot nice. The PC'd ones showed no fouling or leading and shot very nicely indeed!
Hick: Iron sights!
When you say quick load, you mean higher vel? I would mix 4-1, lead to mono & load it over max charge of Unique for an accurate higher vel load. There are other powders of course but accuracy with Unique & lead bullets has always been very good, especially at the top end.
EVERY GOOD SHOOTER NEEDS TO BE A HANDLOADER.

4-1 will give you a BHN of 12.6 which is good for a 45. Probably a little harder than need be but you did say you wanted hardball. Hardball is actually 16 BHN and that is in the 2100 FPS rifle category.
Put 8-9 Lbs your soft lead 1-2 lbs montype and cast away size to .452 and load to hardball length look in lyman book or match to any hardball ammo as a deference and go have fun. 231/HP38 about 5 grians
