I use 200 Grain +P on my 3" Colt New Agent.... I thought I would make up for the shorter barrell with the lighter round and +P..
I don't think they are considered the flying ashtrays... but they are definatley a hot round.... I wouldn't want to be on the receiving end of them...
Hope this helps..
PS Oops I didn't realize this was in the reloading forum.... Sorry guys...
Anyways.. I the the round....
