I would pick the 30-30 over the 243. This has been posted before but it is worth posting again. Start up the printer.

The 30-30 can be loaded with lighter bullets to achieve about 2450FPS loads in the 130 FN grain bullet. Speer has this bullet and it would make the old 30-30 into a 200 yard deer rifle. One can also make the 30-30 into a short range heavy weight using a 170 grain Nosler FN bullet that would be outstanding on Black Bear at tree stand range or 100 yards. I wouldn’t want to try that with the 243 win. For coyotes, I would use my lever action as a two shot gun. One in the chamber and one in the tube. I could use any 100 to 125 grainspire point bullet and push it toabout 2500 FPS to and get great results at longer ranges. As you can see,the old 30-30 can be a very versatile roundindeed.
Happy Shooting
