I'm not quite sure I want to be behind a 260 shooting anything at 33000 fps sounds like I might be seeing some pressure problems on the brass and quick barrel erosion.
You must be using the mag primers for that load . LOL
yeah maybe those guys WERE Right.... my Chrony is off some....
or I got a little overzealous and show how crappy my typing is...
I'll take off a zero so some nimrod won't try to get 33000 fps out of his 260... the type they got all concerned about...
