I've never built a bolt gun on a Remington-700 type action. I've built about 50 M14's/M1A's and I rebuilt my Savage 110 into a nice long action bedded into a McMillan but chambered in 308. I was recently compelled to purchase a JAE-700 long action chassis since they announced they closed shop last week. I will receive the chassis on Wednesday. Now I need to decide on a receiver, caliber and magazine type. I'm open to suggestions and I don't have a long range cartridge in my inventory. I'm pretty isolated to 308 and 5.56 right now. I don't really care about barrel life and I'll be building the rifle myself. A Savage-type barrel nut install would be desired, but if I have to cut a barrel shoulder and finish reaming a chamber, I'm okay with that. What would you build? Tony.
