I have owned 5 different .243 Win. rifles over the years, starting with my first centerfire rifle, a Winchester Model 70 Westerner, with blind magazine up to my current .243's, a Sako A-7 and a Stevens 200. The Stevens shoots very well with all bullet weights, although does shoot best with the Nosler 70 gr Ballistic Tip (great coyote load) and the Speer 70 gr TNT. For deer we load either the 90 gr Speer Deep Shok or the Nosler 95 gr Ballistic Tip.
The Sako is very lightweight and quick handling. My only criticism is that the bolt lift is very heavy to cock the action. My son thinks there is a burr on the bolt that needs to be smoothed out. I have heard that some A-7's have this problem while others are better. One thing the Sako has going for it is that it can shoot the very short Nosler 55 gr SHOTS bullets into okay groups (1.25 to 1.5" for 5 shots at 100 yards from the bench.) The Stevens 200 is lucky to keep 5 shots on an 8 1/2 by 11 sheet of paper! That bullet is extremely short, but the Sako handles it okay. The Sako's accuracy is acceptable, but I was expecting much better results, based on the reputation of the brand. Maybe I just haven't hit on the right load yet. It has shot some decent groups but hasn't shown the kind of consistency I expected. It does seem to prefer the heavier bullets, although it is probably capable of MOA in all bullet weights once I find the proper load. It has shot decent groups with Federal Blue Box ammo in both 80 gr and 100 gr bullet weights, so I am confident I will find a good combination. If you are looking at an A-7, pay close attention to the ease of bolt lift. With mine, I definitely have to take it off my shoulder to work the bolt for a follow up shot. I still like it and have no plans of getting rid of it. I just need to spend some more time working up loads and hopefully the use will help smooth out the bolt as well.
