Let me start by saying that I’m not a reloader. Have thought about it but until now I’ve never had the time or a place. My son is persuading me to get set up, which I’m likely going to do. But first, I either have a really good, or really bad thought.
I have a Remington Model 14 (serial number indicates manufactured in 1913) in .30 Remington. It’s my bush gun and I’ve installed a Skinner peep sight which I really like. I have some old .30 ammo but it’s getting harder to find.
I see a guy on YouTube literally filing 30-30 brass down to.30 Remington specs, or close enough that the very subtle shoulder differences will sort out when the round is fired. Take the 30-30 rim off and enlarge the extractor groove and it’s done.
Now for the idea. I make a shield for my pencil lathe and turn down live 30-30 ammo. 😳
I’m not looking for knee jerk naysayers. I can think of all the reasons not to do this all on my own. I’m old, I’ve seen stuff. I’m asking how to make it safe in the event of a round cooking off while in the lathe. Or drill press, which might be easier to shield.
Thanks
 
You can turn the brass down to chamber, safely. I doubt you could generate enough heat to cook off a round, if your tool is sharp.

BUT

The headspace of the 30-30 round would be about 5 to 10 thou short. You might get some misfires or even a head separation. "Might" but I would not expect it. Worth a try.

However, the 30 Rem brass is available. Buy a 100 pieces. If you don't reload yourself them to me. I will load you a life time of ammo. keep the empties. They can be reloaded 5 more times.

try first with a primed empty case
if the primer goes off, you're cooking the round and should take it slower
if it doesn't... I would still cool the case every now and then with a wet rag.
 
I can't imagine that I'd ever do something like this, but when I put on my Fudd hat, I don't think that anything but a very dull file could generate enough heat to set off a round.

Before I got a lathe I made up some 401 WSL brass from 414 Super Mag with a file, and I could handle it with no problem immediately after filing.
 
I've thinned the rims of 32-20 to make 310 Cadet

it requires removing about .005" or just enough off the base to remove the headstamps. I've done this with live rounds and a modified shell holder in my case trimmer.

forming 30-30 in 30Rem, with the right setup in a lathe should no be a problem, but not something I would do unless there were no factory 30Rem.

you won't find factory 310Cadet ;)
 
Firstly, getting your cartridges set up in the lathe, consistently and repeatable, can be a challenge.

A tapered cartridge like the 30/30 would be extra awkward to set up consistently.
If you start with a deprimed 30/30 case, its easy to center it with the tail stock center.
Turning down the rim and cutting the extractor groove would be duck soup with your small lathe.

I've thought about making 30 Remington this way over the years, but any rifles I've come across had bores too rough to be worth the extra effort.
 
The 35Rem is a totally different case, larger in all dimensions.

To the OP I have more .30 Rem brass than I'll ever shoot, when your set up for reloading I could probably sell you some as I'm
just a little further outside the perimeter too. I just checked and $85/20 + shipping and taxes!!!! Wow!
