2 MOA groups are plenty good, especially if keeping it within 300 yards.
Well..... I'd be a little more lukewarm. They might just be barely adequate at 300 yards, in ideal circumstances. Let's go to the bench and see why I say that.
We've got an 8" diameter paper plate out there at 300yds. It's facing us, dead on, so it looks circular. The rifle is zeroed at 300yds. Now, with PERFECT benchrest technique, the best you can hope for with a 2MOA rifle is for your group to fall in a 6" circle centred on the middle of the plate. Still, that's all the shots in the kill zone, even if some are pretty close to the edges.
Now let's turn that paper plate to an angle of 45 degrees facing us. That represents a deer standing facing us at that angle, and the kill zone is narrower. It's still 8" tall, but now it only looks 4" wide. Now, there is no way the 2MOA rifle can put all shots on target at 300yds. It might just do so off the bench at 200yds. In the field, we might manage it at 100, or even 150yds, but that's now our effective limit for a confident killing shot.
So, with the 2MOA rifle, you limit yourself with angled shots at longer ranges - shots that might be fine to take with a 1MOA rifle. It doesn't matter so much at shorter ranges, or if you only shoot at broadside deer, but it's not realistic to think of a 2MOA rifle as a 300yd rifle.
As I said in my earlier post, my personal comfort zone is 1MOA, and over the course of a season that translates into more shots taken and more deer in the larder.
