there is a block. I's the Davidson single shot bench rest follower from Sinclairs. They cost aboutn $12. You glue it in and your done. if you wanted, score high makes them to go into the magazine on top of the factory follower. Does the same thing, but no glue. I have used the latter with great success.
Building a single shot 6.5x284 on a short action is no problem. Most of the M700 NRA "Any rifles" I see are short action. So long as you can easily pull the bolt,, it's a non issue.
You may consider either removing or weaking the ejector spring though,, so you don't slam the bullet against the side of the reciever when you pull a live round. I think it may induce a little run out when this happens,, but it's speculation.
You'll also need to have the bolt head slightly beveled so the case doesn't hit, as it's a rebate rim cartdridge.
