I have, but it has been a few years since I bought any. Years back a local store was going out of business and I bought several boxes of 500 bullets each at a very good price. Or maybe 250 each, I forget. Less than half the normal price. I shot up several hundred of them and found them to be pretty good. They are swaged with some sort of waxy, dry lubricant, and didn't lead, but the lubricant remaining in the bore looked like leading. It scrubbed out easily. 8.5 grains of old Unique (it wasn't old then!) with that bullet about duplicated factory ballistics. The recent production bullets look the same as the old ones I used.
I have always found Speer's swaged bullets to shoot very well.
Another alternative is the same swaged lead bullets that Winchester and Remington load in their traditional .45 Colt ammo, the conical flat tip. They are often found in bulk packaging at catalog sales outfits like Graf & Sons. They have a sort of concave base to aid in expanding slightly and filling up both the cylinder throats and then the barrel bore. I have found them to shoot well in any .45 Colt barrel. The Speer bullet shoots best in current bore sizes of .451"-.452", but not as well in older barrels that measure .454" and bigger. I prefer them to the Speer SWC. The flat faced SWC may be a better game bullet than the round nose/flat tipped traditional bullets, but I don't use either bullet to shoot anything bigger than rabbits, so even the round nose is a sufficient stopper for me.
