RE: barnes triple shock x
I use H-4831, IMR-4831, H-4350 & IMR-4350 for my 270 Winchester. I use 130, 140 & 150 grain Hornady and Nosler bullets exclusively. I have never have and never will use Barnes copper bullets ever since I witnessed an older X-bullet fail on an antelope. This .257 caliber 100 grain Barnes X-bullet never opened up out of the 25-06 Remington. Depending on what I am going after Hornady and Nosler have me covered for my 270 Winchester
