Dan, just use one of your Arty's (I seem to remember you have a shooter) and buy some Winchester Silver tip ammo. Bullet is soft and should do well out of the 8" barrel for blasting varmits! Hugh's barrel was made from a 30 Caliber surplus rifle. Dont know who made it! He is firing a hot hand load to make it work right! The barrel is really heavy especially at the muzzle. Thor
