Re: Cheap pellets problem K12

thirdwheel: might it be that the persons you loaned the pistol, also tried some really cheap & crappy pellets with it? According to my experience with Gecos in my Anschütz LP-@ I find it somewhat difficult to believe that they would cause the troubles you mention, unless they came from a serious...

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.

Re: IZH 35m

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.

Re: FWB Air Cylinder volume

Presuming that the tank is cylindrical, you may calculate a rough estimate. Measure the length of the tank (L). Measure the diameter of the tank (d). The outside volume of the tank is then Vo = L*3.14*(d/2)^2. If we guestimate that the volume for air is 10% less than the outside volume, then the air...

Re: looking for a proper review of the Anschutz LP@

With that naked barrel, looks certanly resembles the LP2. But the LP-@ has the mechanical stabilizer which AFAIK the LP2 lacks. Also the LP-@'s loading system is similar with the LP10, not with the LP2's "pallet" system.

Re: looking for a proper review of the Anschutz LP@

I have an LP-@. The only differences between it and the LP10 are the weight arrangement, the rotating, adjustable width front sight and the muzzle brake / diffuser. I like the pistol very much, it was definitively an improvement over my Feinwerkbau C25.

Re: Inconsistent groups

Just a sidenote: according to what I know about physics, when the chamber warms up it should expand, not tighten. Heat expansion is like enlarging a photograph, proportions stay the same. rogersdan, when you tested it using a rest, was it a rigid clamp like Ransom Rest or did you hold the pistol in ...
