Wait to see if the law passes then buy anything .243 or larger if it does. Tons of choices.
But if for some reason it doesn't(got my fingers crossed it does!) I have a .450 Bushmaster.
It throws lead that is for sure. Really isn't that bad to shoot though. My girls shoot it and they are 12 and 13. I want to use my .257 if it does pass but would also like to buy a .270 or .30-06 just to have a standard shell that I could buy at Shopko or Walmart if I need a box or two.A friend of mine is trying the fo-fiddy this year. It is a little stout that's for sure.
Even if the law passes, I'll still run my .35 Rem. Trimmed or not trimmed, doesn't matter. It's got the goods.
I really like the 243 for deer but it is even more important with the smaller bore guns to get your skill set "100% on target". Poor placement, say gut shot, with a 243 will be less likely to stop a deer size animal than a 35 Rem. Whatever gun you go with, practice to aquire profeciency will be more important than gun, ammo, camo, sent block, range finder etc.
^^^^I've seen a deer gut shot with an expanding 12 gauge slug ripping a sickening sized hole run a mile. Tracked it by following the pieces of intestines hanging off the brush. No caliber is a cure for sloppy and/or irresponsible shooting.
I started with a 243 and upgraded to a .30-06 - pump action winchester model 760. Awesome gun, dont see too many.
