..............I made a powder compression die for the 38-55 and decided to experiment loading BP for the Uberti Hi-Wall.

These are the swaged slugs I'd produced with the swage dies I'd made. The core was cast of 20-1 then swaged. The OD is .3747", and they weigh 296.4 grs and are 1.070" long with with a .210" deep untapered HP. I wrapped it with Mead Academie brand tracing paper that is .0017" thick. The dried OD over the patch is .3806 to .3808" in checking several places on a few slugs. The boolit engrave nicely, chambered with thumb pressure. The rim stands just beyond flush of the breech, so closing the breechblock engraves the paper.

The right photo shows the leade nicely overides the paper to begin the engraving. If it looks kind of ratty it's because it's been in and out of that case a few times. And if the left side of the nose looks a bit 'off' it's because it's been dropped on it :-) . Fumble fingers.

The case is a twice fired Starline 2.125" which is now 2.117" long. I use a universal de-capper and then just hit about the top 1/2" of the case with a Lee FL die, and then put a slight flare on the casemouth. The case ID is .380". The patched (dry in this instance) booit is a firm thumb press fit down to the wad.

As it's all new to me, to start I took a hint from Jon K. The load he'd been using was 43.0grs of 3Fg (Goex I think) & .200" of compression as a place to start. He was using the Saeco tapered 300 gr GG slug. I got the Lyman measure set at 43.0grs and went from there. What I ended up with is 48.3 grs of powder with a .030" cardwad and .200" of compression. I used Goex also, and it's vintage is unknown.

This will be the point that I begin my experimenting. I have a few swaged 321gr slugs PP'd up and will load these also to see if they'll stabilize. They're HP's also and are 1.172" long. I should be able to try these loads next Tuesday. I have high hopes, but will report back, good OR bad !

Buckshot, I for one would be interested to hear how they fly. Am a PP fan for the 45-70's and even some 45-75's. Never did any 38-55's. Your recipe sounds inticing.

Any consideration for a grease cookie?

..............That will be one of the first changes made if there are problems with these and fouling.

Are you sure that the load is 48+ gr of powder?? My 38-55s will only hold about 45 gr uncompressed of GOEX FFG and I use a 300 gr NEI boolit at 42 gr for my rifle.

................It's 3Fg powder I'm using. Yes, the charge is 48.3 grs, and is sent through a 24" drop tube. It sits about .300" below the casemouth. Charged cases in the loading block are then held against the threaded stud for the lid on my vibratory tumbler, which settles the powder a bit more. It then gets the cardwad and .200" compression.

If your slug is a GG type it will be a bit longer then a 300 gr smooth slug for patching.

Buckshot that is one fine looking cartridge, don't see why it won't shoot like a hot damn.
