Thread: Airgun pellets - How light is too light in spring guns ?

I personally won't use alloy or copper. I have a tx200 and after getting tired of reading the arguments about weather or not to use metal brushes wrote to air arms who said don't use metal brushes (brass or copper or cleaning rods) as they run the risk of damaging the thinner lining of the barrel. Air rifles are not as hard a metal as powder guns. For this reason I don't use alloy or copper pellets. They are a harder metal than lead pushing their way down the barrel.Lead residue fills in small inperfections in the barrel and leaves a miniscule layer which is like a lubricant, alloy doesn't.
I got a lot of good advice from kiwi air gunners site. It's a bit of a quiet site, but some of ppl there know there stuff. Guys who are constantly buying, rebuilding, tuning their guns. (Looking at you billbob, as one) Go there and ask their views. I have no drought some one will have had the same rifle and can check notes on various weight and head sizes and point you in right direction.
