RE: A good day, a very good day.......
Before I would sell that 1-48 barrel, I would test it. You might be surprised at how well it shoots. Also that is an excellent deal on the rifle. I have a Lyman Trade Rifle with the same barrel but in .54 caliber. It is without a doubt a great shooter and I'd never part with that barrel for nothing.
Those Sabertooth are nice conicals. That's some good shooting you did there. Looks like the deer better carry a range finder and make sure they stay more then 100 yards away from you when you have that rifle loaded in that manner.. Again, nice shooting and a great deal on that rifle.
