Re: working up Ladder loads at different range
Yes, you can shoot a ladder at 200, but its not going to be as informative as at 300. My suggestion would be to shoot it at 300, just adjust your aiming point up to a size you ar comfortable centering on. I know, psychologically it feels like you have a handicap with the 4X but Ive seen 10" groups shot at 1000 yds with irons... with the right sized target.
That said, If you just don't think its do able, I might have a scope around here somewhere you could borrow... I think [img]/ubbthreads/images/graemlins/smile.gif[/img]... somewhere
