I have owned:
Wby Mark V Ultra Light 280 Remington
Wby Mark V Accumark 280 Remington
Still own:
Wby Mk V 7mm Weatherby Magnum
Just got back from the range about two hours ago. Chronoe'd 140 A Frames at 3400 fps with one hole grouping. And, 120 Tipped TSX at 3650 fps with 3/8" grouping.
I sold both of my 280's because I prefer my 7 Wby. Both of the 280's were 1" guns. I work with several guys who own the Wby UL's and they all love them.
To be honest, the UL's accuracy can be hit or miss but I have yet to see one miss.
PICK the 280 !!!!!
