I found about a hundred big bore bullets. They weigh 506 grains and are about 1.350 in length. They are round nosed and have a lead tip. Any help with ID.

Butch, any idea of diameter? Compare them to what you have there if you don't have a mic.

They measure 458. My Grandson is in for Christmas break and we were loading some 454 Casull. He dug around and said let's use these. I said these ain't pistol bullets. My mind is cluttered and now I know they are just 500 grain hunting bullets that I bought some time ago for my 458 Lott rifles and my 450-500 that I bought from you several years ago. I probably need to sell it as I have too many 458 rifles and a 416 also.
