I love my X-Bolt. It's the best money I've ever spent on a rifle. It's a .243 Varmint Stalker. I had the guys at Cross Canyon Arms in Ogden put in a new trigger spring to get the pull down to 1.5# but besides that it's all stock. It shoots 55 gr BT's, 58 gr V-Max's, 55 gr Blitz, 62 gr Varmint Grenades, 55 gr BT Lead Free, and 60 gr. Sierra HP's to the same point of impact and all of them grouped no more than .6" at 100 yards with no load development whatsoever. I just picked a starting load of Varget or IMR 4064 and put any one of the above mentioned bullets on top of it and it has worked great. It's not going to win any benchrest competition but it's killed a lot of coyotes and rockchucks!!
I've been in your exact situation concerning rangefinders. I started with a Leupold (love their scopes but I agree with you, the rangefinders are junk!) and then upgraded to a Zeiss PRF thinking it would do what I wanted it to. The Zeiss was all right but would not hit small targets at extended ranges. I ended up selling it at a loss and finally buying the Vectronix. If I had it to do again I would have skipped the Zeiss and saved my money for a Vectronix. I would have been money ahead to buy the best in the first place. My Terrapin was considerably less than $2000. I believe they are priced similarly to the G7. It's a hard decision to make when you want something "right now". Save your money and get the best you can afford even if it's going to take a while. Next time you're in Twin contact me and I'll let you try mine out if you want to.
