Re: CO2 to O2 conversion

I am quite sure deadeyedick is confusing pure oxygen (O2) with air, the latter being a mixture of 78% nitrogen, 21% oxygen and 1% other gases. Nobody in their right mind would use pure O2 as an air gun propellant because it might ignite the lubricants.

Re: grip putty

I've been using Locktite Kintsuglue, AFAIK similar with Sugru. Somewhat expensive and probably not suitable for building prominent shelfs but very easy to use, feels a bit gummy which I like and should be easy to remove without leaving stains.

Re: How to break into Olympic competitive pistol shooting

Competition grade pneumatic APs like the IZH-46 and the FWB 100 series have their charging levers under the barrel. The lever moves vertically and there's no difficulty in keeping the grip while charging and loading the pistol. As for the prices, where I live new top notch centerfire and rimfire pis...

Re: FWB 65 Special Trigger Wrench

I've got the FWB "special key" shown in _nc513_'s pic and in dino91's ebay link. Its short end fits nicely into the hole of the 65's trigger weight switch. The long end can be used to turn the fine adjustment screw inside the switch. Since a FWB 65 is today as much a collector item as a sp...

Re: FWB 65 Special Trigger Wrench

You do not need a special wrench to flip the 500 - 1350 g switch back and forth, any max 3 mm diameter metal peg will do. I can operate mine easily with the longer limb of a 2.5 mm hex key.

Re: Pistol Pellets: 7.0 gr vs. 8.2 grain ?

Proving my point! Now there's 1/10th less "time-in-barrel." I repeated your calculations using a more convenient formula for the relation between distance, final velocity and time in an uniformly accelerated motion starting from rest: d = ½vt => t = 2d/v and got about the same results. Bu...

Sub-six for precision target, then adjust the backsight and aim just below the whiskers for rapid fire target.

It hides behind the hump of the grip.

waxman: why should we talk about TOZ-35M, when OP explicitly asks about IZH-35M? They are two different beasts, and only the IZH needs snap caps - or not, I'm not sure. The front face of the firing pin has a flat surface that should hit the back of the chamber and prevent the harm done by dry firing...

Re: Remove cylinder after each session?

Great minds think alike... I have utilized Rover's idea for some time. I use a rubber grommet that is intended for lining holes in sheet metal. Had bought a set of these for another projects so it did no even cost any extra. I keep the grommet in place all the time except when actually shooting pell...

Re: Can a Feinwerkbau 103 win a P44???

It's not the arrow - it's the Indian!

Nice looking pistol BTW. I own a FWB 100 and at my skill level there's not that much difference in results with it and my "best and most modern" AP, an Anschütz LP-@. But the latter is less tiresome to shoot so that's what I use in competitions.

Rover, I sincerely hope that you are not a heretic.

The gun starts to move backward at the very same moment as the pellet and air start to move forward. You know, conservation of momentum and all that stuff.

Re: The New ISSF Air Pistol Finals Format

Showing traces would be cool but it would also be a perfect excuse to get rid of the politically questionable projectile-launching and go entirely optic. Which I'm afraid is ahead anyway, after firearms and lead are banned.

Re: Technique, goals & reality.

Perfection is an abstraction, like a straight line in mathematics. You can define what it means and picture it in you mind, but you can never actually draw a perfect straight line.
