    Ah, yes, the ubiquitous Floberts. Got one myself. The vast majority of cheap guns in that era had frames of malleable iron. White iron castings were packed into airtight boxes surrounded with a oxidizing material, and soaked for many hours in...

    As I understand it, all primer compound has powdered glass in it. Purpose being to hold heat long enough to get the powder to light. This had been true almost from the beginning of time. It was an issue for the .22 belly-shooters between the...

    Yah, probably more lead in the air, too. I wouldn't recommend using them indoors, tempting as it may be, without aggressive ventilation.

    Working into it backwards using Quickload, pressure to launch a 30 grain bullet at 800 fps. from a 18" barrel calculates to just short of 4000 psi. Those CB caps are probably less. I'm just guessing at the weight of the bullet and the muzzle...

    Um, those use a larger than normal amount of primer compound, which contains ground glass. Hard on the rifling. The bigger reason I quit using them altogether in my good rifles was because they built up a nasty ring of hard fouling which interfered...

    No problem. Pick up a used Stevens 44 or even a Favorite, reline the barrel and you're in business. These can be had off Gunbroker for as little as $400, sometimes even less. If you're a bit more flush, a Ballard is has more cachet. Chamber with...

    Forgive me please, but what instrumentation did your shop have that was precise enough to "calibrate" gage blocks? What was your reference standard? Serious question, not snark.

    NOE has several .25 moulds that work. The 260-86-FN is mighty close to that old Lyman number. He can do 4-cavity moulds, but why? You're not casting pistol bullets for an army. Personally speaking, most of my bullets for my .25-20s have come...

    I'm more likely to put a liner in the barrel, but that's just me. And I only do Stevens single-shots at that. I've read that setting back Win 52 barrels was a common practice in the belly-shooter era. Throats would get worn from the ground glass...

    A long-time truth in the metrology field is that your instruments should be an order of magnitude more precise than the tolerance you're trying to measure. ---------------- Repeatability is addressed in a way at post #30. Given a micrometer...

    In the decade when those were being used, they were "duplex loaded", with a few grains of smokeless under the main black powder charge. Fouling was almost nil. From the ASSRA site, I know that he's planning to continue that tradition. ...

    The .35 Rem when it was new was loaded the same as the common 200 grain loads are today. Still, I'd like to see him take good care of his old rifle. Since this is a cast bullet forum, get a 358315 mould or equivalent, cast with 50-50 wheelweights...

    According to legend, when Rabbeth developed the original .25-20, (the Stevens version), he preferred the lighter bullet, since what he wanted was a squirrel cartridge. But the ammo companies issued it with the 86 grain bullet on the theory that it...

    John, have you actually seen a 28-30-120 with the lug? I've scanned my database, and have found only lug-less examples. Not that there are many, since the .28-30 was only offered for a couple of years on the 44 chassis.

    If the barrel is any good at all, it will be a fine paper-puncher. Check out the twist of the liner. There is a guy in the ASSRA shooting mind-bending scores off the bench at 200 yards, using a 10 inch twist and 120 grain plain base bullets in...
