fellas i have an old rem 700 bld delux in 222rem. the rifle is in excellent shape but i want to do something a little different with it. I have wanted a 22-250AI now for about 3 years and i am thinking now or the near future is the time to make a move. My question is about the bolt. My bolt is a 223 bolt face and i need a 308 bolt face for the 22-250. My rifle is from the late 60 or early 70's so it should be a pretty decent rifle ( i guess anyway. it seems everyone likes the older rifles for whatever reason) I dont know what it will cost to have this bolt face opened up and a new extractor installed so i dont know if that is an option or not? The other thing i thought about was selling this bolt and buying a kiff bolt in 308. I think thats going to cost around 150 bucks. I could probably sell the old bolt for 75 to 100 bucks, I think anyway?? I dont know much about these kiff bolts, like if they need fitted or trued up? the action hasn't had any work done to it so the receiver face will need trued anyway. thats another 150 bucks. I plan on putting a shilen #17 barrel on this rifle, but i guess that really doesnt matter for this topic. So what method would be best cost wise and performance/ accuracy wise. Have the original bolt re worked or buy a Kiff bolt? Any ideas? Thanks Lee
