If a 4.50 pellet seems to fit in slightly loose,where would you get a larger diameter?Using R-10 lights but not snug enough.Trying to read the threads but tooooo many for today.Any thoughts?Are vogels better?

what type of pistol?

'loose' where?
in the loading area, or when the pellet contacts the rifling throat?

4.52 seems to be the biggest diameter regularly available (here in AUS) - This is normally stamped somewhere on the container. If your supplier does not have the containers sorted by size it menas hunting through his stock to find the diameter you are after.

Its a Steyr Lp 10.Its loose where you put it in. Not really loose but not snug. My LP 1 is too snug with 4.50mm and I see that its target shot when new, by the company, used 4.48mm. I shoulds buy 4.48mm.Is pilkguns the only ones to carry vogel or is there other high grade pellets in sizes?Ron

A pellet being snug or loose when inserted into the chamber has little to do with head diameter, but more to do with skirt diameter relative to chamber diameter. Skirt diameter is typically 0.01" greater than head diameter. Whether snug or loose, the skirt will expand from the release of the compessed air and form a seal against the chamber wall and then against the bore as the pellet moves down the barrel. For best accuracy the diameter of the head of the pellet should be matched to the bore - thus the choice of head diameters ranging from 4.48 to 4.52mm. This matching is determined by group size, not by how the pellet feels when inserted into the chamber.

IMHO choose the pellet diameter used by the factory for the test target. When you can consistently shoot over over 570, you can then take some time away from training and practice to shoot groups from a rest and select an optimum pellet and head diameter.

Fred,

I disagree.
When inserting a pellet into an LP10, head diameter has everything to do with a felt snug or loose fit.
As it is inserted with finger pressure, the skirt is never pushed into the chamber/rifling but sits proud of it.
The only resistance felt is the head of the pellet entering the barrel.

I can't speak to the LP10, but on my LP1 -
As they enter the chamber, both 4.48 and 4.50 pellets are equally 'sloppy' fit. Finger pressure moves the pellet forward till you can feel the head engage the rifling, and at this point the base of the pellet (the skirt) is about 1.5mm proud of the chamber opening. Further finger pressure pushes the head into the rifled bore until the pellet base is flush with the chamber mouth. The feel of both 4.48 and 4.50 pellets is the same during this final movement and is what I would call snug. The factory test target was fired using 4.49mm pellets.
