what cartridge?

[troy_mclure]

i got some .452, 553.5gr gascheck boolits.

what the heck gun are they shot from? cant be a .45colt can it??

[.45Cole]

I put my guess on a .459 sized down. What do the lube grooves look like (really shaved off?)

[AJ Peacock]

Maybe a 45-100 or 45-120 Sharps? They have a .451 groove and could handle a heavy boolit.

theres 1 lube groove with lube, and an empty groove. hasnt been shaved cause you can see the mold lines.

look like factory boolits?

[mpmarty]

Could be for paper patching to .459

perhaps a heavy boolit for the 460 SW or one of its cousins. if there are lube grooves on the boolit, it would not likely be for PP.
