Thanks again for all of the advice.
I went with the Tikka - ordered it from Able Ammo tonight. They had a very fair price (558 + 15 shipping). I'll be otd for $588 w/transfer fee. Only Buds had a better price (by $7), but I didn't feel like sending them a check. I'll make that up with the points I earn on the card anyway.
It was a hard choice, but I went with weight, the crisp Tikka trigger, and accuracy I'm already familiar with. The CZ 550 is a beautiful gun and I would be happy to own one, but I wanted a light hunter/stalker. I'll be mounting a 12.5 ounce Bushnell 4200 elite 3-9x40, so I'll be around 7 1/3 pounds total. I think I'll have a nice deer rig.
Now for load information! I already have the dies, brass, bullets, and N540 and Varget powder. I think I'll start with the N540, which is a tad bit slower burning than Varget. Any suggestions?
