I am currently refurbishing a old .177 BSA Mk5 Meteor with new spring, seals etc for use in and around the shearing and machinery sheds on rats and rabbits, from 0-30m.
It's over 20yrs since I plinked with an air rifle and there is now a wide range of hunting pellets, from a standard looking pellet with a pointy poly tip to plastic pellets with brass tips.
The ones that looked most promising were those in the pic, but at 17.5 gn they only suit pcp guns.
Does anyone have any experience/recommendations in this area?
