    Go easy. The rifle is a historical treasure. Hot-rodding that Winchester reminds me of the old practice of stuffing Ford V8s into a MG TDs that was popular in the early '60s. Rich kid in my high school drove one his father had had built. The...

    Ok, then the issue is how much pressure the rifle is good for. Those days, black powder and plain base bullets was all there was. Unless you loaded with extremely fine grain powder and/or very light bullets, about 1600 fps was all you were gonna...

    Jacketed bullets in soft barrels wear down the rifling pretty fast. First the leading corner gets rounded. That creeps toward the center of the lands until the center starts to wear down. A number of Stevens 44s were spoiled this way. 60 grain...

    High grade competition ammo isn't achieved by sorting. It is done by applying very tight limits to every step of the the manufacturing process, and constantly monitoring. This means much more in-process testing and measurement is done to assure...

    The thread is about the utility of measuring / sorting ammo to gain improved performance. Not about accurizing a particular brand of rifle. O.P. asked about measuring rim thickness. I've never found any improvement at all from that, so far as it...

    Dittos. Using a rim gage to "upgrade" bulk ammo I think is nearly fruitless. If they're shipping badly upset cases, there's gonna be a lot of other, more important quality factors that will also have high variance. The second-worst of these...

    OK, good. I have no experience with it in mine. Dad had a Lyman 358315 which I got with the rifle when he passed. He said in his notes said he'd lapped nose larger to make it work. The RCBS looks a lot alike, so I though I'd ask. n.b. his...

    What is the diameter of the nose of RCBS200, forward of the full-diameter groove portion? Looks like a bore-rider. Anybody actually used it in a Microgroove Marlin? This guy casts the RCBS-200 in lots as small as 100. I've bought from him. ...

    I have three 450s. Never knew there was anything but the brass piston. I never use a lubrisizer cold. Just a mechanics' drop lamp applied 20 minutes before I start a lubing session does me fine. Lay it aside when I start. If the lubrisizer...

    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...

    There is a story, perhaps apocryphal, perhaps not, that alteration of standards that way was a sabotage trick used by forced laborers in Nazi arms factories.

    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...
