    Pietro's suggestion does sound the most likely, although of course only if it is located under the rimfire firing-pin. Brownells used to market a device for curing this condition with a .22 although I think it was expensive and/or discontinued, and...

    The first gun I ever owned without air coming into it, was a 9mm. Webley garden gun, which is actually a slightly smaller calibre than that sounds. I have several pounds weight of Fiocchi cases, primed but never loaded, which I bought in an auction...

    You wouldn't. But the problem of patching the ball is a little more than it is with a muzzle-loader, in which the ball tightens the patch around itself as it goes down, which suggests less danger of being blown out of it on the way up. Wrapping some...

    That must be a calibre less used in straight cases than just about any other. It is very rare for anyone to actually need a wildcat cartridge, but there is a little-known .35/.30-30 Winchester that is about as practical as I can think of, for...

    Nor many people would give raw egg or oiy sardines to a dog with Lanty's whiskers, and regular steak is a bit much, when he likes toasted cheddar just as much. But my wife got a deeply coveted job in January, and Lanty got his own personal steak...

    Well, my wife is German, and she has more non-antique shotguns than I do. I tend to think of Colonel Fremantle on the field of Gettysburg - although I've got his book, and he had neither red coat, teacup nor official position. Talking of civil war...

    That is an encouraging start, but an instructive test requires no firearm, just a piece of squared paper, 52 squares by 52. Instead of buying some you could draw and print it with the draw utility in MS Word. Number the columns 1 to 52, and the...

    This isn't unusual, with various types of slug. The trouble is that groups at 100, with any kind of smoothbore projectile, tend to be a lot more than twice as big. I also think the slight spin a rifled slug can achieve arises in the air, and not...

    I don't think Longbow's or the FBI/DOJ's judgements would surprise anybody with a serious interest in the subject. A spirally grooved slug can indeed spin, but to an extent that can't possibly stabilise it. Archers did indeed discover the ...

    One reason for that is that websites like eBay, where you can see the individual piece of leather illustrated, blew them away. I don't think they make boots thick enough for an all-leather sheath. You can buy a sort of miniature plane with a...

    Those are good recommendations, but there is a lot to be said for an air hardening steel, such as A2 or D2 (or possibly A-2 or D-2 in searches), which should simplify the heat treatment process. Not all of the single shot actions require heat...

    The trouble with these conversions is that they have been done by different people, at different times. They have a reputation of being dangerous with the .45ACP load, but I think this applies mainly to GI hardball. Unlike the break-open Smith and...

    Huntingsgr8's revolver is very much like the one with which, in .450 calibre, Henry Webley did a demonstration in front of press witnesses in 1884. In fact it might have been the 2½in. Metropolitan Police model. At nine yards he placed five shots in...

    It still looks off-centre to me, and I would also suspect something home-made. it could be true that there is no evidence of firing, for someone who didn't reload could have replaced the shot in unfired cartridges. In general paper cases simplify...

    Filing a court order to exclude guns from what amounts to history seems a bit silly. But the book is fiction, and the rest of the Civics class probably had something to say about the sort of countries where a military court can impost an original...

    As a very great generalisation, subject to exceptions, deficiencies in accuracy caused by the rifle make 50 yard groups half the size of 100 yard ones, a tenth the size of 500 yard ones, and so on. They often spread the group in a particular...

    That looks like a fine piece of work. The Baker was about as good a compromise design as a pre-fulminate and pre-Minié could get. The longer-barrelled and smaller-calibre Kentucky rifles held certain advantages, but probably fouled even faster. ...

    I think excessive headspace is likely to produce an unusually sharp edge around the perimeter of the primer, or extrude it slightly into the pocket's bevelled edge, especially if the bevel is exceptionally large. But I can't see how headspace would...

    If it didn't have an inertial firing-pin I would say the pressure of the firing-pin is involved, probably in combination with wear on the extractor hook or the snapcap rim - very likely both - to form inclined planes to make the extractor rise under...

    I don't think that is due to excessive pressure at all. The usual way that goes wrong is by detaching the depression, altogether or in part, around the edge of the depression. What you have sounds like a firing-pin problem that can occur at about...
