Normally degrease the entire action... rebuild without any grease or lube. Hammer running surfaces polished. If anything feels tight or graunchy it gets polished. Grease collects dust, gets where it shouldn't and changes viscosity. Not such an important consideration for 10m shooting where it's all ...

Doing this w/o a pressure reducer is a disaster waiting to happen ... one of the reasons air is much safer is there is NO possibility of an overfill. You don't need a regulator, just a careful approach. If you have something like a 50L or a valve that's a little hard to operate easily, get a flow r...

Don't bother. I have mentioned tped in various occasions (see my links above) yet some people still can't find any legislation for vessels below 1 liter or where the 10 years period comes from. It's not that you can't find the legislation, it's that the legislation pointed to says 2.5 or 5 years, n...

Many things can affect air rifles.

Most stocks including the ally ones warp.

We end up free floating most and running them with polished internals and no lube, with different seal materials to combat the -7 to +40 ambient we can shoot in with FT. Otherwise we can see massive POI shifts.

Re: Crazy rules

You will now need a two foot breach flag for your air rifle! The rule states the flag must extend through the full length of the barrel!!! Who dreamed that up? This came from us "colonials". Our 3-P air rules require a Clear Barrel Indicator (CBI), since it's hard to check the "chamb...

The manufacturers of 10m air rifles have designed barrel length and number of rifling twists with a velocity of around 170/175 MPS so every thing is optimised for the tightest group. Deviate to far away from these parameters and the group will open up. Steyr found that the Anschutz barrels used on ...

The velocity for Olympic air rifle should be 170-176m/sec. It depends on the weight of the pellet and the recoil the shooter prefers. In higher velocities you loose accuracy. Guy. You don't. Unless you count single figure mm CTC groups at 50m as less accurate? Normally it's a pellet problem. But th...

What are you going to do about the non altered factory rifles which leave the factory running 12 and 20 ft-lb? Walther, Steyr, FWB and Anschutz have all made target rifles identical to their 10m versions which run out of the box at higher power. (they do carry different model numbers sometimes and s...

Right, so even though you may have got a rifle from Steyr, you might have fitted a bottle from anywhere in the world and it might not have a stamp. So do you scratch one in yourself?

As i've said before, the ISSF assume everything is off the shelf.
