I was wondering if anyone has any experience with the Barnes TSX for hunting? Currently I am using 405g RN with IMR4198 and new Starline brass. Winchester LRP. I have seen the Barnes TSX kill a lot of deer in other guns. Mainly a 25-06. I was wondering how the performance and wound channel would be in a (.458) 45-70 round. These bullets are all copper and hollow point from what I have looked at at my local bass pro shop.
