Making a 7RM shoot

[mdesign]

Picked up a used R700 chambered in 7RM a while back and have not yet been able to find any load it likes. Bore scope shows the throat to be in good condition and the rifling and crown generally look good. Bedded the rifle, etc..etc... but nothing makes a difference. It's a 1.5" @ 100yd rifle. Sure that works for hunting but was hoping for better.

Is the 7RM an inherently accurate cartridge or can they be tough to find just the right load for? I think it needs a new/better quality barrel but kind of reluctant to do that and end up with the same level of accuracy.

you measure the twist yet? You may need to adjust bullet weight, powder, etc. Only know a couple guys with 7RMs that handload but they are solid sub-MOA shooters.

Chris is correct with the thought process of checking for adequate twist rate for your bullet weight.
If that is not your issue then you have answered your own question: New Barrel, your best bet IMHO

It's supposed to be 9 twist but guess it would not hurt to confirm. I expected a worn throat or crooked chamber but looked pretty good with the bore scope.
