I didn't really spend too much time with it as I've moved from .177 to .22, but I can't say it made the crappy pellets I did try shoot any better to be honest.

I think the idea is consistency, so same head size into the bore for close enough to same friction - less velocity drop from tighter fitting pellets etc. really just trying to eliminate every 1% of possible inconsistency. I dont know how the Robb one works but I have a small one that you drop a pellet into and push it through - it will basically just shave the soft lead if its oversized, or squish it a little.. |

Yep, there's fixed size push-through items which is what yours sounds like. This is adjustable, the taper is super fine.

well after head sizing 1800 odd AA .177 pellets today, with a vernier, I'm over it.
How did that pellet sizer work you were getting in from the UK work out Myson? I find sizing makes a difference in the sig. May be because it's unchoked. 4.50mm, 4.49mm definitely shoot better groups than 4.52mm and 4.51mm. Will try 4.48mm and 4.47mm now I have an abundance of them measured. Have a enough 4.46mm and 4.45mm to see if it's getting far enough off spec to affect groups now too. But God I don't want go thru that again. Thankful hades 22 only come in 250 pieces tins. That will be the next mission, 400 odd. Gaakk.
