Hatsan 135 .30 cal big bore break barrel penetration test

hatsan carnivore 135 .30 cal penetration test obviously the rifle at 550 fps could not go thru the empty propane canister so I gave it a little help from dieseling spraying the pellet skirt with silicone spray making the carnivore more powerful,I don’t recommend dieseling because it may damage the rifle by blowing the seals and may endanger the person firing the gun but then some air rifles were dieseled on testing feet per second like my swiss arms tg-1 @ 1400 fps only dieseling can accomplish 1400fps sma
