451 diameter bullets in 45 Long Colt

I'm considering reloading for 45 Long Colt with jacketed bullets. Most Hornady "Heavy" bullets are .452 diameter. I want to load the Lighter .451 diameter bullets (45 ACP?) in the Long Colt. Will this pose any problems? I just gotsta know.

Should not be a problem regarding diameter. May need a tighter crimp to keep 'em from backing out in the cylinder upon recoil.

Also, I would not think that accuracy would be as good - but, who knows!!

Yeah, the accuracy crossed my mind. I'm really looking to make a load for just plinking around. I don't like using lead bullets. Too much of a mess to clean up for me. Some folks might like cleaning the lead out. I don't.

Don't give up on lead boolits!! With the proper fit and hardness, they perform as well as or better than jackets. The two leading causes of leading is improper fit and harness ... as for clean-up, I have more problems with dirty powders than I do with the lead boolits ... just a thought!!

only way to know if .451 will work well is slug your barrel...

Smiths are generally tighter than Rugers...again...gotta slug the barrel...To do so...pound a piece of soft fishing sinker lead down the barrel with a hammer and dowel and then measure it with a dial caliper...take several measurements and then average them....my guess is the .451's won't make a hill of beans diff...so start with the .452's

Since learning to cast...I don't have much need for commercial pistol ammo except what I carry for defense

Leading is not a problem unless you use full house loads...high velocities cause the leading issue...say over 950 FPS....I've never seen a need for hot lead loads personally..The lighter loaded ones are generally more accurate anyway
