My browning x-bolt in 223 does not like 63gr win. pp which is the bullet I wanted to use so I have been using 55gr rem sp which are just about gone I like to buy in bulk and do not like to spend a lot on bullets for a rifle that I use to shoot pest and a meat deer during a doe season.I have ok luck with the 55gr rem but would like a little tougher bullet.Is there a difference Hornadys with or with out the cannelure? How about the Hornady 60sp in the slow twist barrel and on game?
