wymberley Posted December 14, 2020 Report Share Posted December 14, 2020 That I've really touched an air rifle. I've just discovered what all the experienced guys no doubt already know and that is that a pellet sizer falls into the same category as the common or garden shotgun bore gauge.

Ultrastu Posted December 14, 2020 Report Share Posted December 14, 2020 Its a waste of time .and useless gadget . pellets are automatically sized to perfection as they are pushed into your barrel so to presize them is pointless. Unless for some weird reason you want to make them too small for your bore . Which is generally what a pellet sizer will do . Quote Link to comment Share on other sites More sharing options...
wymberley Posted December 14, 2020 Author Report Share Posted December 14, 2020 Yep, I was pretty sure that something was amiss when having "sized" a pellet to 4.52mm it then fell through a 4.50mm sizer without touching the sides. Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted December 14, 2020 Report Share Posted December 14, 2020 The head of a pellet is usually around 4.50 to 4.55 mm the skirt around 4.58 - 4.63 mm this is so it makes an air tight seal in the bore and fills the lands and grooves of the rifling. If you push your pellet through say a 4.51 mm sizer , your skirt will now be 4.51 mm obviously. And then be undersized to do its job .By The way the skirt is usually the most important part of the pellet as far as energy and accuracy are concerned ,best not to mess with it too much. I've found that actually flaring the pellet skirt out to a wider size can improve energy and accuracy .and is something I recommend with h+n pellets Quote Link to comment Share on other sites More sharing options...

Memory failure I fear. I seem to remember that back in the day we had not pellet sizers but shapers which would re-shape the skirts of damaged pellets before they went into the barrel.

Mr.C Posted December 14, 2020 Report Share Posted December 14, 2020 I understood that the pellet skirt flared out to fit the bore with all that air pressure behind it. Quote Link to comment Share on other sites More sharing options...
