I had a Weatherby Ultra-Light in 338-06 and have 2 Finnlites, one in 270 Winchester and the other in 300 WSM. Here's how I would grade the advantages of one over the other:
Weatherby:
Stiffer Stock
Sako:
85's have better stock geometry
Smoother action
Better Trigger
More Accurate
Better magazine
Feeds Smoother
Windage adjustable mount system (with Optilocks)
Better bolt, 3 lugs fit better than 6
Better ejector, blade style
Holds more rounds in WSM's - 4 in mag
I think that the Weatherby Ultralights are good rifles, Sako Finnlites are Great rifles. Both of my Finnlites have shot better than 1/2 MOA at 200yds with premium hunting bullets. They handle great. I wouldn't mind hunting with a Weatherby Ultralight one bit but I'd trade one in a second for a Finnlite. My 2 Finnlites are about the last rifles I'd ever trade...............................DJ
