Ok, that makes sense. I thought it should have slightly more capacity than mine because mine is Creedmore length (body). I blew out some taper and sharpened the shoulder so it looks like I only lost about a grain of capacity. I know that short powder column is looking really efficient. We can get 3100' with160's in a 26" barrel.......rich

What load are you running? My SAUM is 3030 with a 160 matrix with 61.5 Ramshot magnum in a 24" tube. It is not a hot load.

Can't remember for sure, but I think it was 65 grains? Rhian chrono'd it in his rifle. He was using RL33. He actually clocked 3184', but he has a 29" barrel. We figured a 26" would easily make 3100'......Rich

Re: Gap 6.5 s case capacity

Obviously it would be a lot more trouble than just using SAUM brass, but would it be possible to form down from .300 WSM brass if thats all you could find?

I tried WSM initially and it won't work because the case body is way too thick to become neck material. Most of the cases will be destroyed and the rest would take a lot of machining to be useable......Rich
