Re: Which action/barrel do i buy? need help
It sounds like you have some money to spend and are not sure quite how to go about it.
First, does Remington offer a factory chambering in 204 Ruger? I assume they do as it is a pretty common/popular varmint caliber now.
Assuming they do, why not just buy an off the shelf rifle and be done with it?
If that doesn't suite your needs, another option is to scour the local pawn shops, gun dealers, online services and locate a 223 Remington for as little money as possible. Buy it, send it to a smith, and have a new barrel chambered in what your after. Then your all set. If the budget allows for it, have the action tuned up at the same time.
Then you find your stock, maybe have it pillar bedded, and your off to the races with a pretty good rig to build from. Triggers, bases, rings, optics will still need to be sorted out, but at least you got the fundamental portion out of the way.
