I have looked at them too since I really like Sako & Tikka. The A7 has a few improvements over the Tikka, better bolt, bolt release safety, better/stiffer stock, 5 shot 1 moa, metal feed lips on the mag. It also has a safety release on the mag where you have to push for release. They say less chance of loosing it the field. I could do without that feature, feels tricky at first.
Forgot a couple things the A7 has two action lengths with the .22-250 being short. I like the single stack mag.
The gun has a pretty solid feel and shoots good. Being a half breed between Sako/Tikka it is priced that way. I think the best price currently is around $720 with no promotions.
