RE: Remington Mod. 798
I'd bump it up to a .308 or 30-06. Too very easy bullets to buy, and the bullet range on the 30-06 is 110 to 220 or something like that. I'd feel much more comfortable with that in my hands than a 100 grain .243. I used a .243 from the time I was 8 'til I was 12. Then I switched to a .308, and would never go back to a .243 unless I had to. Now I mainly use a .45 grain muzzleloader.
