Slammer, since no one is answering your question, mind if I detour the thread with a couple questions?
How accurate is your Optima, and what are you shooting? I have one and like it a lot, but with triple 7 pellets and XTPs I'm getting 4" at 100 yrds.
Still accounted for a couple bucks this past fall, but I thought I'd try to improve that once I used up the triple 7 pellets.
Thanks,
Ella
