There are so many "Advice" or "Advice needed" threads, or variants thereof, that I lost count, besides which, they were mostly about script writing.
So I don't suppose my starting yet another Advice thread for oiks like me, requiring mundane answers will make much difference.
Start from here:-
I have found my old air rifle I had from over 60 years ago and thought I would give it a whirl, but I see on'tweb there appears to be at least three variants of slugs - I remember only the dome topped ones.
I do remember it took .177 pellets, but is there anything to be taken into consideration over shape of same?
