PRS, I know how Lee works on this stuff. I will have to weight till I get home to check OAL and bullet length. No- I will not shot this bullet in any rifle. Yes, .454 is much better than .452. I will do some more research then you can coach me and perhaps I will be better prepared when I call Lee,. And yes these things originally shot 230 gr. however, If I can make a 200 gr design to care enough lube for BP, this would be the most desireable. Heck, if I am going to have to shot 230 gr. in order to carry enough lube, to heck with it, I would just load the one you design and shot 250 gr. That's an idea anyway, glad I thought of that. I think I'll try it.
