If a 30-30 round won't chamber there is really something wrong. the

What I would do if competition shooting with a rimmed cartridge and
used brass would be to full length resize all the brass, at least the
first time, and make up a dummy cartridge as a master for how deep to
seat the bullet, unless of course you always use the same bullet.

With a tubular magazine you also need to decide how heavy a crimp you
need to keep the things together :-)

Generally speaking, unless you are going for the last FPS you can
squeeze out you aren't going to have a lot of case problems... I am
assuming that you are not trying for the last possible foot per second
in muzzle velocity for cowboy shooting ... and if you were to load a
30-30 to its original specifications you probably will never need to
worry about the cases.

I hear that.

For what it's worth, this ammo came from my late father-in-law's
collection.

I went through all of that last night.
Factory loads (Winchester and Remington) were exactly 50 mm long.
Some of the handloads were 1 to 1.5 mm longer. So maybe...

But the real difference, and I'm guessing the reason these rounds (six
of then) wouldn't load is that the necks were bigger; fatter.
4 or 5 thousanths? Could that make such a difference?

Yes indeed. And they could..could have been reloaded as 32
Winchester..a cartridge that is identical to the 3030..but uses a
slightly larger diameter bullet.

I need to go back to school reading inch micrometers.
My large frame ones are all metric, but he small ones are inch.
I confuse easily these days...

A cheap digital caliper is a very good tool for the handloader. HF
sells em for under $15 and its all you need.
