Depends on what manual you choose….
Hornady shows max Norma case length @ 2.270”…..
Western shows it @ 2.274”….
EDIT:
I read the Western info wrong…..max length of 2.284” also…..

Ready for a total sh11 show. I have cases that vary .022 in length, from New to fired in the rifle. A far cry from a match batch... I also cracked a Norma neck even after annealing.

Which die do you have? I started at the shell plate minus a quarter turn and it was about perfect... I had the rifle in hand and squeezed them no more than needed. I have a lee die...

This appears to be a lot like 30-30, easily way oversized. My die was used and dirty, so I polished the expander with scotchbright and gave it a fine film of Redding sizing wax. The first dozen or so were smoooooth. My expander is .310.

I have Lee dies; I use PPU brass and have never had an issue. I do have a few boxes of old Norma 7.7 ammo and some once-fired Norma brass but haven't tried reloading any of it.

I also have ppu. I planned on using the Norma for jacketed and ppu for cast. I'm going to focused on fire forming this batch of 50 and getting a good load. Then I will play with cast.

I hope everything works out well!! My best results have come with .312 bullets, specifically 174g Hornady SP, over either H4350 or IMR4350.

My bad… I’m using Green, expander is .310. Had to use the Rock Chucker and a good but of wax. Shoulder profile looks way different from before and after.. Norma 1st fired but not from my rifle (I think)
Remind me of sizing rifle case..crank sheel holder all the way up, screw down the die till it stops?

I cut mine to 2.265 leaving some on the table for the shoulder to blow forward. Rifle sizing is generally to shell holder lower ram and go another 1/8th of a turn to take up slack. I find that In a lot of situations that way overdoes it. I started to shell plate back off 1/4...

What powders you guys using? I’m looking for a light charge that won’t get stuck in my barrel
Primers… Large Rifle?
can’t wait to shoot my WW2 Arasaka bring back. Probably has not been shot since Japan. Was found behind a water heater during renovations of my buddy’s ex. That was a good 20 years ago
