Actually when I first read your post I figured I'd try it with the heaviest pellets I have and get back to you. Very low velocity prob because of gas loss at the barrel/cylinder gap.I have heard rumors about some shooting slugs in their SSA’s.
I was puzzled by that as all slugs for the .177 seem too heavy.
Thanks for your reply, thought it might be my breath.
