I'm going to add my voice for 30-30, scoped or not. In fact, since the 30-30 has a much more limited range than .243, .270, .308, 7mm-08...oh the list of longer range rounds could go for awhile...since the 30-30 has a more limited range, aperture sights are a great choice for a 30-30.
I have chosen a Marlin 336 with Skinner aperture sights. Granted, I'm not going to be shooting across the valley with this, but I can still fill my tags.
.45acp, .40 S&W, 9mm, .38 Spl, .380 acp, 22lr
12 gauge, .223/5.56x45mm, 30-30 Winchester
