Long range airgun shooting

[flims]

maybe a silly question, but isn't the air thinner at night? (less resistance), just before sun down?

Are you likely to get better groups long range without a silencer?

air gets thinner with Elevation not by night or day. if you are on very high land where air is less dense projectiles should fly further, and also in hot countries.

at long range you dont need a silencer, the weapon can't be heard. my Infinity at 140 yards doing 57ft/lbs can't be heard but the 31grain whizzing through air can be heard as loud as a whip if you are about 30feet from its line of path. im always amazed by how loud that subsonic projectile is.

This is what i did today at 150 yards, power set at 70fpe using bisley mag21.4,very light wind was left to right, it took me 20 shots to set up and shot a 10 shot string with 3 pellets not hitting the target at all, should be getting a vidi-cam-corder soon and will try again, don't think i will do much better as i hate paper shooting

Yep, I thought it might be..

Geoff, Re- PTFE lined barrell.. how did you do it and what made you choose PTFE over the superior, more wear resistant, UHMWPE ? I'd hazard a guess at melting point, or was it a coating thickness issue?

[GEOFF]

The PTFE is only on the barrel where the hammer (piston) runs, it makes the firing cycle much smoother. the hammer which has two PTFE rings fitted hits home much better all this helps with consistency and accuracy

ah.. I see.
