The 235 grainers feed fine. The cartridges seat on the shoulder in the spool magazine. My MS will feed empty cartridges.

I normally try to seat bullets so the loaded cartridge is near the maximum length but I may have seated these a little deeper to provide enough neck grip I would have to check my records.

I have never had a case jack but most of my shooting has been at a range. I slowly cycle the bolt so I can grab the fired case and then cycle the bolt home.

You wrote: "The old Hornady 3715 (.375, 270g. RN) worked just fine." Are these discontinued? Is there a cup & lead replacement?

You wrote: "Member Kuduae, however, has advised that he has used Barnes 30486 (.375, 235 gr.) while seating them further 'out' to more closely match the finished profile of the original cartridge." I guess I stayed away from homogeneous copper bullets because I was concerned that they are too tough for vintage gun barrels? Do you have any thoughts on that.

It is great that you mention Quality Cartridge. I believe their brass is excellent.

Quality used to provide loaded cartridges. For me, the sad thing is that I used Reed instead of Quality because Reed said they just finished a run of 8 mm Sauer and the owner of Quality told me it would be a while before they could load the Sauer. A couple of years later, I talked to the owner and he said he decided to focus on just the brass.
