    Why did the army adopt the 1903 Springfield rifle 3 years before they adopted the 30-06 cartridge?

    What with all the criticism of 1903 design and metallurgy, I think we might have done better to just cough up the bucks for a Mauser license and adopted the Model of 1905 .30 x 2 1/4" (7.62x57 to the European crowd.). We would have quit paying royalties after the Kaiser sank the Lusitania anyhow.

    Effects of Lubrication and Pressure on Bolt Face Forces

    More than I thought. The debunker debunked.

    Effects of Lubrication and Pressure on Bolt Face Forces

    My old article's point was that as you get back towards the head of the case, it is not expanding to "grip" the chamber, where a stretch ring is seen on a case with lots of head clearance. So all that is holding the case head is the strength of the thin brass case wall. Which is not a lot...

    It is just that they kept revising the numbers.

    Smith vs Colt

    I wonder just how many M58s have been customized to death by people who had to have a fixed sight .44 or .45 because a .41 just wasn't big enough. My Pythons were durable enough for PPC and IDPA but I do recall the case of the guy featured in Tyler T Grip advertising. "Faster than Ed McGivern...

    Effects of Lubrication and Pressure on Bolt Face Forces

    Interesting, I get the idea, but where is the force going in the dry chamber? Somebody once critiqued the AI claim that a straight case binding to the chamber wall loaded the bolt less than a tapered case "wedging back out of the chamber." He calculated that the cross sectional area of the...

    Why did the army adopt the 1903 Springfield rifle 3 years before they adopted the 30-06 cartridge?

    I think it is the other way around. The .30 1906 was a 150 gr flat base spitzer akin to the 154 gr 8mm. But everybody wanted longer range, so ca 1924 we went to the M1 173 gr boattail while 8mm had jumped up to 196. Around 1940 we went back to 150 as the M2. I read (yeah, Hatcher) it...

    Garand Glue

    I recall reading that NM shooters would glue their Garand hand guards into one unit. It is all epoxy these days but I remember mention of use of "GE Glyptal." But like Loctite, there are a dozen different grades with different industrial applications. Do your records and recollections go back...

    Screws and Glues

    A friend was digging out a broken off red dot pistol sight screw and he has plenty of company. I have heard of a lot of loose screws, too. Are there stronger screws and adhesives dot shooters could be using? I ended up with Loctite 271 (red) on an iron sight rib, the blue and vibratite were...

    45acp revolver

    Take a look at the cylinder wall thickness vs chamber thickness of a 1911. The 25 series will certainly take more pressure but anything over ACP +P is more than I care to experiment with. I doubt brass is going to reinforce steel much. I read of the notion a long time ago in a gunzine article...

    45acp revolver

    Oh, yeah I have a good supply of Ranch Products clips, and some Wilsons. My application has been for 6 and 2; I don't have any 1917 half moons at all. I wish I could find my picture of some of the alternate designs by Smith. There was one that looked like it was competing with the revolver...

    Bar and Chain oil

    They SAY that, then slather their guns with Ballistol. Mineral oil plus oleates probably as emulsifiers.

    Lever gun caliber decision……45 Colt vs 44 Magnum/44 Spec

    There are some Marlin .45s on Gunbroker. Prices are high, I found one plain vanilla that sold for $1000.

    Updates from Taxidermist

    I don't know the time required but a friend got his African trophies in with each mount screwed to the inside wall of a crate, assembled so the heads and horns were a 3 dimensional jigsaw puzzle to minimize the size of the box.

    1911-A1 Series 70 Slide stop problem. Colt brand mfg. 1980

    Right, under extreme service, surely he would cut the "retro." If I get bored, I will swap some slide stops around and if there is a difference gun to gun, I will try to measure plunger protrusion. Wonder what the spec was. Found it, .222" straight from the stop shoulder to a .045" radius...

    Bar and Chain oil

    Are there vegetable gun oils... besides Froglube? Animal fats? ETA Come to think of it, I did see bear lard for sale at a muzzleloader show. Only $20 a quart. I have read of "lard oil" on machine tools. Seems to be diluted with mineral oils, though.
