Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Loading the Italian Vetterli-Vitali 10.4x47R round

Well, here’s my toy, my $200 pickup after selling the Gras bayonet that came with it, see link to the rofle here: viewtopic.php?f=14&t=3843#p25509

CASE - Now to loading the round. It’s like a ‘bulky 30-30’ on steroids, where the rim is 5/8” or so in diameter and takes a sloping taper to the neck for the ~44-Mag sized bullet. It does have a semi-defined chamber and it will be interesting to see what the cases look like after firing. Oh, I got pre-made cases from Buffalo Arms for about $2.20 each.

BULLET - My bore mic’d out to 0.429” which makes it ideal to shoot 430-sized 44-Mag cast, of which an old timer gave me about 700 or more weighing 240-grains. Of importance to NOTE the original gun fired a “heeled” bullet.

DIES - Being an admitted cheap bazztard, I’m not paying $150+ for the 10.4x47R dies from C&H, so where these are longer than the case in the Swiss Vetterli, I bought a used set of Lee 41’Swiss dies on eBay for $20. Add in the oddball #17 shellholder for my hand primer and I was off to the races.

LOADING - Well, that was a chore, the loaded rounds wouldn’t chamber. I knew it wasn’t due to the bullet as I took a spare 3/8” muzzleloading ramrod and put it down the bore to the bolt face and put a mark on the road with a thin Exacto blade right at the muzzle. Then I pulled the ramrod up 5-6” and took a shorter dowel and stuck a 44-Mag 0.430” sized bullet into the throat and held it there with the dowel. While holding the bullet firm, I pushed the ramrod back down to touch it, then carefully made another mark. That gave me a ‘maximum’ overall length for the cartridge.

Seated to be just above the large grease groove and on a large driving band to crimp into, I was below the max length. So I knew it had to be because I am not using a heeled bullet and between the case wall thickness at the neck plus the bullet diameter, she's just a ‘tad too tight’ in the chamber.

SOLUTION - Using a trick my Dad used to use, I removed the decapping pin from the sizing die and put the ’loaded cases‘ back into the sizing die. I only went in about the amount the bullet is in the case, but it worked slick!

NEXT - Off to the range! Stay tuned ... and note that ‘YES’ I need to re-profile the nose of the seater stem, as it is cutting into the base of the bullets (tad over-sized for case, but I try to minimize or eliminate neck flaring, to make my cases last longer.

I have loaded for mine the same way, but using a cast bullet from a Lee mold, I think 310 grains. I use a .303 british die, with decapping pin removed, to "re-resize" the loaded rounds.

Read that and tried that too ... but my 303 sizing die didn't do anything ...
