Just came from the Hornady site. I've been trying the 45 cal 300 XTP's as they come from Walmart. The Hornady site shows them with BC of .18. The 44 cal 300's show a BC of .245. Seems if I want to shoot an inexpensive 300 grain jacketed HP I'd been crazy not to use the 44's. Am I missing something here? I did go to MMP to order sabots for them, and see the green .429-.430's suggest a maximum bullet weight of 260. Think I have a problem shooting the .430 300's in the green sabots in my GM barrel?

While I was at Hornady, I ordered some 390 HB-HP conicals to de-virginize the 54 cal barrel which came on my old Cabela Hawken and is now (thanks to Sabotloader) interchangeable with the 50 GM barrel. I'll be boring you with the results from these soon enough!
