If you dont reload Id go with the 22-250 just because you have a 270 and prob want a good ground hog size game gun and will find plenty of factory 250 ammo to fit the bill. If you reload then Id lean toward the 243 since you can load the 243 with some pretty light stuff that would do great on hogs but the light bullet factory ammo isnt abundent. The 22-250 will have a ton of factory stuff around the 50grn-ish bullet that will be perfect for smaller game.

If you didnt already have the 270, Id also vote for the 243.

I like the CDL over the BDL. I like the satin blued barrel and the fact its a clean barrel. I dont like having to take sights off and put filler screws in if I have the choice. Thats asuming you're going to scopea 22-250 or the 243 you won't use thebranch grabbing open sightsany way.
