Marrakai and Wharf,thanks for your resplies.
I have been using some Westcastings hardcast coated 180 gn projectiles and gradually increasing the MV to around 1100fps with no loss in acuracy.
I've just got to find something to test the penertration on.
Plenty of pigs in the hills above me so will soon find out if they work..
I will keep you informed.......
