If your wanting a nice Deer Bullet try Hornady's .243 100gr BTSP it has a higher BC than both bullets you are looking at and I will tell you it flat out works.
I have had nothing but good results with them. Old School that beat New.
I been using barnes bullets for years. I have been using barnes TSX and TTSX with 243 win and I have to use them in some parts of California. California has some areas that are lead-free for hunting. There are other brands on the market which that are lead-free. But I prefer the Barnes bullets.gun)anyone try either of these in their 243? any preference? wanting to try a new round in this season
