Thanks for the info. I really think this is the cartridge I'm going to go with. I like everything about it. Shorter case for long bullets, lots of selection, excellent brass, etc.
I would start out shooting like that by any means, but I'd like something I could use if I got good enough. I can make a 350 yard shot pretty easy, but after that a lot of things change. From the JBM calculator it has over 1100 lbs after 1000 yards which is plenty of power. Honestly the furthest I'd probably ever need/feel comfortable with is 6-700 yards max. Now for target there's no telling what I may try!
