If you want to darken timber, the classical method is ammonia fuming. The timber is placed in a reasonably air-tight container (an improvised polythene 'tent' often used for furniture), in which there is a dish containing a small quantity of stong ammonia solution. The timber darkens progressively, ...

You say ejection is fine. I presume that is extraction of the fired case? What about extraction of an unfired round? If extraction is difficult, the chamber is likely to be tight on the case. Target rifle chambers are tight, but not that tight. What does an extracted unfired bullet look like? Is the...

Stick your hand in your pocket, but make sure you always wear the same clothing, or hook your thumb over your belt. This allows you to relax the non-firing arm, so reducing yet another variable tension in your stance. Well, that's what I was told - seems reasonable.

Indeed, and that's one of the reasons given for alloy stocks. However, alloy and steel have different coefficients of expansion, so one wonders at the wisdom. Whatever, target shooters get pretty obsessional about screw torque.

Perhaps Mr Swartz means that competition .22 rifles are pretty well 'bedded' straight from the box, whereas hunting-type rifles often leave a lot to be desired, and it is those that mainly receive aftermarket bedding attention. The forces between action and stock are much greater in a high-powered r...

This is actually a profound question - I hope it stimulates an erudite discussion. There is a lot of misinformation around concerning bedding and other technical issues. There's a lot of information to be found on the 'net, but a lot of it is suspect, and some of it is quite wrong: be careful! After...

Lammy100 asked:

Which parts have actually needed replacement and ~how many rounds fired?

I regret I don't know, since I'm the pistol's third owner, however I doubt that there have been any replacements and I'd expect many thousand rounds.

If I understand you correctly, I had a similar problem with my FAS magazine. As the bullet nose dropped into the mag, the cartridge rim stayed put, with the result that the round wedged itself in the mag. A bit of deft work with a file sorted out that, but it still feeds reliably only with the short...

Oh, Lammy1000, I'm getting forgetful... Re your other post: spares included with my IZH were a firing pin, recoil spring, hammer spring, extractor, extractor plunger, second sear and second sear spring, so I guess the factory expect all of these to wear or fail. Rather strange, however, that an appa...

My third-hand(?) IZH came to me with the grip safety disabled, so I haven't got first-hand experience of doing this job, however, it looks pretty clear... Do you have an instruction book and exploded parts diagram? I downloaded one from somewhere - sorry, can't remember URL, but if I found it easily...

Is there some confusion between compensator and muzzle brake here? Also, some of the science of muzzle 'flip' has been explored in another, recent thread.

I recently looked at a Konus 80mm zoom spotting scope, available locally at a bargain price. First impression was how light it was. Optically very good, but I think its body is made of plastic. Looking into it, through the objective lens, what look like glue splodges suggested the lens elements are ...

Are we talking TOZ 35? Aren't you going to have to remove the front sight anyway to fit the compensator? The exploded parts diagrams and the GA drawing I have for the 35 (not M) shows the front sight body, 'band' and ramp to be a single 'lump', apparently permanently fixed to the barrel. The sight b...

You might be being unnecessarily cruel to the questioner. What does 'best' mean? OK, all those listed may put the slug through the same hole, so are accurate, but there are other important parameters which are implied by 'best', such as reliability, longevity, quality of materials and manufacture, d...

As a myopic spectacle-wearer, it's an everyday experience tthat distant things are fuzzier in dim light, when not wearing specs. This includes target bulls! So if I shot without specs, I'd expect POI to change with large changes in light levels. Problem is, I can't see the sights either! As stated a...

The answer lies above.

Perhaps the question should be 'How well is the compensator matched to the gun and the pellet?' Sorry, I don't know the answer...

About blow back free pistols: the movement of the breech also participate to the recoil since it is a moving mass (much heavier than the bullet) and modifies the balance of the pistol. Thtat's why for RF pistol the trend is to reduce the mass of the breech as much as possible. If the case and slide...

I believe Webley made an 'auto-unloading' target pistol, which was a blow-back action, but which did not auto-load, so it's been done. I've never really understood why the idea hasn't been resurrected for free pistol use, because of its apparent advantages. Spencer is right in that, in principle, th...

Action = reaction: remember? The force acting forwards on the bullet is equal to the force acting backwards on the base of the case. Let's ignore chamber and barrel friction. If the case has to stay in the chamber because the breech remains closed, the gun starts to recoil as soon as the bullet star...
