Hi Team, Just bought a 4 year old LG110 HP privately, GinB FT stock, Evolution butt plate & Tasco Custom Shop 8-40x56. Into the workshop last night and found it was running significantly hot with JSB Exact 8.44's so followed the excellent Steyr videos to turn it down. Why doesn't Air Arms do this instead of sticking that stupid anti tamper on so you can't get legal. When I received my brand new AA410 and crono'd it, that it was also running hot so had to send it straight back. Before you ask, yes I have had my crono checked against a new Chrony and it's very close. Anyway, my question, what does the little circle of grey foam do apart from get caught in the the breech every time I cock the gun? Can I remove it without the gun self destructing? Thanks, Rob.
