I got great groups with 45-240 XTP in my 50 cal Optima, but I;ve been reading a lot of posts about poor performance on deer.

I wanted to move to the 45-300 XTP, but all I can find in the stores is 44-300 XTP or 45-300 SST. I like the hollow-point design of the XTP more than the spire-point SST, but I'm not sure I like the thicker green sabots that are required with teh .44 cal XTP bullet.

Does anyone have opinions on these two bullets, or do you know where I can get some 45-300 XTP bullets? (Even Bass Pro On-line says they are out of stock.)
It's not rocket surgery, for crying outside!
