Thanks for the postimages.org info, I edited the original post and it looks like it’s working now.

Still haven’t got around to measuring the real twist, but I’ll get it soon. The local gun shop’s gunsmith told me he thinks the 77 grain round will keyhole/tumble at 300-ish+ yards. What do you guys think? I find it hard to believe that’s the case if it’s grouping so well at 100.
