For killing hogs, he old standby lead 250 - 255 grain RNFP will do the job nicely. I load for my Uberti Cattleman 7 1/2" 45 Colt using the cast bullet from the old Ideal/Lyman 454-190 mold - the traditional 45 Colt bullet. I cast 'em, tumble lube them in paste wax / alox and load them over 6.5 gr. of Red Dot. Extremely accurate with good results on paper out to 50 yards (the max distance I could shoot at my backyard range on the farm).

You can buy pretty much the same lead slug from a number of suppliers - .452 - .454 will work fine. I tried the traditional Unique load but had better results with RD - a lot less dirtier than I was getting with the Unique. Every revolver is different and every one has their likes / dislikes.

I cast all of my projectiles for pistol/rifle and haven't bought a "store bought" round in years. Everyone has their own preferences - but why buy high priced jacketed when a lead slug has done the job for many years.
