[wvbuckbuster]

Anyone ever use CFE in the 6.5x55 Swed. with say a 100gr. Nosler BT? Got the idea and was just wondering. Thanks, Dan.

I have used both BL-c2 (quite similar burn charachteristics) and H380. Never did a very thorough test as it was just to use up some oddball components for practice ammo, but accuracy was reasonable. I was using 123, 130 and 140 grain bullets of various makes.

Thanks for the info and replies. I have some of this laying around and just thought I might give it a try. Thanks again, Dan.
