If I may respectfully offer some advice..... :)

Please do, that's what I'm here for............

I would suggest asking an experienced spring powered airgun shooter at the club to have a go with your rifle to see if the grouping then becomes consistent and tighter when they use it. If it does, you know the 'problem' lies with your technique, and not the fault of the rifle or pellets etc. ;)

I think you're right. I'll ask Brian to throw a few down the range and see if he can offer any advice.

..........some rifles don't like being shot with any support apart from the shooter's body mass.

Interesting. The range doesn't really accommodate  being slumped on the floor but I shall tinker with my stance to see if I can discover something that produces more consistent results.

Dieseling could be the couse of the inconstancy............

Really? Is there ANYTHING that DOESN'T affect consistency?

You'll be telling me that the weather is a factor next!!!!

Well, the temp will affect springers, warm weather thins the grease allowing the piston to move faster, cold weather will thicken the grease, slowing the piston but this might be offset by the fact cold air is denser so more air goes into the compression chamber, if your gun has ultra fine machining tolerances then the warm weather could couse the metal to expand and pinch components, wind affects consistency, altitude/barometric pressure and temp affect consistency as the higher you go the thinner the air gets (less air goes in to the compression chamber) same thing with air temp (warm air is thinner) rain in all it's forms will affect where the pellet lands, some scopes are affected by temp.
It would be easyer to list all the things that don't affect accuracy and consistency
Hope this hasn't dampened your enthusiasm  ;D

Also, the warmer/thinner the air, the faster and easier time the pellet will have flying through it.

Likewise the opposite is true with colder/denser air.


Don't get hung-up on it though, as you can't change the situation, but just be aware that when trying to print tight groups at long range, varying weather conditions can have an effect on results, albeit slight.

The 'weather' is fairly consistent in the range: bloody freezing!

Even in doors there can be a micro climate, at my old club if you shot near the wall (lane 1) in the indoor range in summer it could be 5-7 deg C warmer than lane 6 just a few yards away, in the winter it was a lot cooler.

My eductaion needs a boost; I have a question about AO scopes.

If I am short-sighted and use the eyebell focus to ensure that the reticle is sharp is is "valid" to use the AO focus/paralax correction to bring the target into sharp focus?
