I wouldn't shy away from the 243, the only reason it has a reputation for accuracy issues is the Superlight or compact models are very heat sensitive, folks shoot them hot and expect good accuracy, but for a deer hunting round, the first round is the one that counts and a possible second maybe, that's very doable even with the Superlight, I have a couple of em, both shoot very well, you can see what the third round will do on the target below, that's three consecutive shots at 100yds within a couple minutes.
