Schpank & Spender... absolute gold right there!

Very good, you sound like you are on the money with what you need... I made that 600 yd hit with a Buckmaster on 18X and it was convincing, not entirely ethical shooting I agree but we were culling ferals and any that were wounded were quickly dispatched by the 338LM to my right or we zapped over on the Quads and the .223 was used at close range.

Having said that, a Sightron III has just been purchased so I can see clearly where I am shooting (Missing) and place the shots with more confidence.

260 you say?.... should just be enough for squirrels. I'd limit myself to under 100yds... they can be tough little suckers..
