Thanks for all the advice y'all. FG, I think I'll see how it shoots before I float the barrel. Chances are, I'll eventually do it though. It seems simple enough. The other day I picked up some T/C "Big Shot Sabots" (400 grain XTPs) at BassPro for cheap. They were on sale. I'll see how they shoot, but I'm not expecting much. That seems like a bit much for my little .50 cal and a 120lb deer, but we'll see...
