I loading for 7 PRC now and only used 175 ELDX. They shoot real well for me. Federal is making a Terminal Ascent bullet (170 grain) that looks intriguing as a bonded high BC bullet, but is nickel plated. I’m interested in this as a hunting bullet for large Whitetail deer and the bonded feature should work well for weight retention. Is there anything negative about the nickel plating on these bullets? More erosion of rifling or more difficult to clean the barrel, as compared to copper clad bullets? Thanks
