I'll second the 38-55! Here's my #5 smokeless action in same. Had it done up to be a light sporter for whitetail hunting. 
A friend is having his re-lined to 30-30. 

I also have a NYSM 50-70. Been using 3.5 gr Trailboss. Use a 3.1 cc Lee dipper to measure and the Lee 450 gr cast bullet. It's a near full but non compressed load as should be for TB. Shoots well enough for plinking. My rifle has a decent bore and I'm sure I can come up with a better mix.

George, to test whether my resized cases were filling the chamber, I backed the 7mm FL die off a quarter-turn and sized and trimmed to length several cases. They wouldn't chamber. Ran the die back in, resized, and they chambered. So I'm indeed filling the chamber. And NO powder gas or particles in the face and no bright ring on the case. And no pulling the barrel and machining it. I think we are comparing apples and oranges- after all, there are THREE sets of specs involved- the original German specs, whatever Remington used, and current SAAMI specs. I (very crudely) measured a 1913 DWM round, a 1935 FN round, and contemporary PPU, Hornady, and R-P rounds. I measured head to shoulder break and head to halfway down shoulder, the standard headspace measurement. The contemporary cases seemed to measure 2 to 3 thousands LONGER than the 1913 and 1935 cases. My resized cases were 2 thousands SHORTER than SAAMI specs. Major gun companies, including Remington, were notorious for varying specs back then. Was I shortening the cases? Well, my cases seem to measure 2 thousands less than the specs called for in MODERN RELOADING by LEE, but roughly the same as actual old rounds. Numerous writers I've seen quoted in ASSRA postings have specified pulling the barrel, setting it back a thread, and replacing in the receiver. Using the above method, anyone wishing to fire a #5 safely can do so without buying anything, even  a form and trim die. Well, except for a small metal-cutting disc and mandrel from Lowe's to trim the cases. That's real scut work. What are your thoughts, George?

P.S. The necks on my resized cases are bulged or expanded too. As was a #4 .22 RB I had. The case mouths would split upon firing. The steel in some of these Remingtons was pretty poor, apparently. Perhaps that's what happened to your #5.

REALLY. Incredible. Thanks, gonna try that tomorrow. Uh, what kind of tape?

Oneatatime - that is a gorgeous rifle! 

Conincidental to this discussion, last night I loaded some 7mm for my Uruguayan rebel carbine. I've used both methods to fire form the brass - tape on the base and expanding the neck with a .30-06 expander, then using the 7x57 die to neck size back down until the breech just barely closes. Both methods work, but I prefer the latter. Annealing the case necks is a must.
