78Staff , It's a subject that gets overblown . There really is no problem shooting 44spl in a 44 mag . just like shooting 38spl in 357 magnum revolvers . Everyone talks about the crud ring left behind from spl cases making it difficult to insert 44mag loads .
If you only shoot 44spl's in a range session , just clean the cylinder well afterwards and there is no problem . I use Kroil or Marvel Mystery Oil and a tight patch to clean carbon from the cylinder charge holes . Works every time. If 44spl cases is what you have , load them up and have some fun .
