My uberti 62 police has to have 380. With 375 there was hardly any lead shaving at all. Matter of fact the balls even fell out of the cylinder as I was loading it. Ordered some 380 problem solved!! If 375 is all you can get they'll do but from now on all ill use is 380.
As long as there is a lead ring shaved off when you seat the ball then you'll have the right sized ball.
Neemo: So if you want these horses, I sell them to you. Did you bring some gold with you? John Chisum No. Neemo: Silver?
John Chisum: Just lead!
