Yep, I would really look hard at that Savage Model 12 Long Range Precision Varminter. It has what all 22-250's should have a fast twist. If your a reloader you can shoot 75 grain bullets, with less wind drift at longer ranges than a 55 grain bullet. Most 22-250's use a 1-14 and your usually limited to bullet weights up to 55 grains.
This thing looks sweet. H-S stock, which are tough and not cheap looking like plastic injected molded stocks. They have a aluminum bedding block, made to fit the single shot action. They have that funky right bolt left port, but I guess a fella could get used to that.
They have a considerably heavy barrel compared to most factory varminters. I think around 1'' that will help you when the shooting gets good. They have the adjustable accutrigger. If I was to buy another 22-250 it would have to be this model.
There's an article on this very gun in Novembers Shooting Times. The author shot 3-shot groups only, but at 600 yards he shot a 1.79'' and another 3.87" with Swift Sirocco II 75 grain bullets. Using that new IMR-4007ssc powder.
