I am a fan of both the 300 and 257. The 300 has been my go to all purpose cartridge and it has served me well. The 257 is great for deer, antelope, and hogs.

I just helped a friend setup his UL in 240 and it was a sweet rifle. We shot it yesterday and it was printing nice little 1/2" clusters at 100 yards with 90 grain NABs. It now has me wanting one as well! The UL has a 24" barrel but does not have near the blast or recoil of the 257 so it might be a nice compliment for my other Weatherbys.
