I do have some experience loading this round. I found it not to work well with cast bullets in my rifle. The chambers tend to run large, and freebore was "generous" on the rifle I had. Forgot the weight, but it was in the 170ish range. A .312" RN cast with gas check liked to impact sideways at every velocity I tried. Bore was a little sketchy, but not a sewer pipe. Accuracy with .311 jacketed bullets was acceptable given the crude sights and 2 ton trigger pull. It was no Swede M96, but was accurate enough to reliably hit an 8" gong at 100 yards. Unless your new brass is seriously out of spec, you should be fine with just working the necks.

Starline recommends that you at least run a expander through the necks. They said they have a coating on them to keep the from tarnishing that needs removed.
I have always sized new brass with the exception of the high end brass. Some times I do some times I don't.

What is this "new" brass that you speak of. I thought all brass has been fired at least once.

I’m not sure when everything went to bags but I do remember getting empty brass in boxes. Anyone that’s ever opened a bag of chips, knows that’s not the most secure container.

Take the decapping stem from your Lee die and put it into a Lee universal decap die.
The universal has a body large enough to not touch the outside of most cases and uses a pistol decap rod with no expander, swap that part out and you have an expander die that can’t size.

Some quality brands of brass do not need to be trimmed but I do always chamfer and deburr after running them through the full length sizing die. I pretty much treat them as OF brass without need of length check. OP you really need to slug your bore. Especially if you plan on using any lead bullets. As others above mentioned the bores on some mil surp rifles can and do vary a LOT. That is unless all you want to do is make noise. I don't see many reloaders that fail to try to gain accuracy as that is one of the main benefits.

I size and trim all brass before loading, I had some 6.5 Grendel brass that 10% was over length and some 6.5 Creedmoor that had extreme differences in length so I trimmed all to the shortest length. I lucked into 500 6.5x50 (Arisaka) that was both new in box and once fired, the once fired was more consistent than the new in box.
