    Lanty Hanlon the Irish terrier is only 40 pounds, but under normal circumstances very boisterous, and well aware that energy is proportional to the square of velocity. But he defies the laws of physics by levitating onto my lap, as lightly as a cat...

    I think that quality drill bits are more accurately dimensioned and sharpened than they used to be. You can get a smooth hole, very close to the drill diameter, by drilling with a couple of undersize drills, and then following up with a drill on...

    That is an extremely bullet-shaped bullet, but on game probably doesn't tend to go club-headed as one with a wide meplat will do. I don't think Lyman #2 alloy would be bad, but agree that less antimony would be a good idea, and quite harmless with a...

    The suppressor or silencer was developed around the same time as they were for the internal combustion engine, and there are three main reasons why they were seldom or never used by the few diehards who still used muzzle loaders at that time....

    Thurlow Craig, my favourite author on shooting, fishing, cowboying, animal behaviour and South American revolutions, recalls returning home hot and tired at night, and gulping what he thought was a glass of water, left out by his Paraguay cook. It...

    John M. Browning designed far in excess of black powder requirements, enough for some extremely useful and practical high velocity smokeless loads, which I have no qualms about using in my original .40-82. But nothing exceeds like excess. I...

    You have had some good advice on alloys. Antimony is cheaper than tin, so it is used in wheel weights on a scale that makes bullets brittle. Also any large hollow is going to make any bullet likely to shed its point. Here is one that I feel almost...

    That is a disappointment. There are surely high-temperature synthetic rubbers, but a sandwich of inner tube rubber might well do better. It might be that the flange of the steel "mushroom" has eroded, and is allowing excessive access of gas to the...

    For questions like this a piece of old-fashioned graph paper and a pencil can be useful.

    I think the "at the feet" part is exaggeration, but let's not dwell too much on detail. This British Baker rifle target (like the Intelligence Corps, which didn't have any privates) used to be known as "The Eunuchs" I can't think why, can you? ...

    I once saw a prisoner of war movie where a guard is trying to make civilised conversation about his home in Hamburg and a British pilot said "Yes, I believe it is a beautiful city. A lot of open space... " Most British people would consider that a...

    You might find someone makes an off-the-peg mould for .318 bullets, for the J-bore version of the 8x57, and even a lubesizer die would be cheaper than a custom mould. Or you could make a simple die. The cheapest way of getting a .315in. reamer is...

    Ah, Neuschwanstein, as copied by Walt Disney! Ludwig was unquestionably as cracked as the Liberty Bell, but probably not certifiably insane by modern standards. He built castles from his own fortune and irresponsible borrowing, not tax revenue. The...

    Sliding down fairly easily works well with medium-hard, heavy-bullet and heavily-charged .450 long-range rifles. That bullet might be a little longer, which I think is what controls upsetting (weight of lead compared with cross-section), but I am...

    I think there is a pretty good chance that a land diameter bullet would expand if it wasn't too hard. But a grooveless bullet would probably be better. Imagine the opposite, stretching a piece of rubber rod with grooves in it. Most of the stretching...

    Lawns are overrated. I like them best when they are long enough to see gusts of wind moving across them. I think it would give less than 120psi pressure until there was more resistance than a bullet would give. The usual mechanism was a hammer...

    File steel is some of the best for making knives, wood chisels etc. But the file-making process can leave cracks or some other form of weakness deeper than the teeth look to go. Belt-sanding that little bit deeper is a good idea. I have refreshed...

    It is puzzling to know why there are so many bad files around. 1095 steel isn't an expensive material for the bulk buyer - probably cheaper than the quick and easy forms of case-hardening - and about as good as anything for straight razors, which...

    I know how it is. I think the sphere reservoirs were often of copper, and I would guess that they were thick, made of two hemispheres with an interlocking flange, and silver soldered together. I believe they had a valve so that they could be...

    Yes, gasoline and various common solvents, or their vapour, are liable to come sneaking out looking for trouble, while powder stays where it is put. Gasoline combines with the oxygen from about nine times its weight in air too, so a pound of it...

    I think the difference with cans lies in the metal being intensely but momentarily heated by stress. Think of the heat generated by bending a pieceof wire to and fro till it breaks, being concentrated in a single millisecond with no chance to be...
