Here is Report on the .257Wby.
Bought this rifle in 2000'. Broke in the barrel per Lilja instructions on his website. Was accurate when it was new.
Shot 5/8" 5 shot groups @ 100yds. After approx. 60 rounds it started to get finicky. Sometimes it shot great, sometimes it sprayed fliers, 2" off course.
It used to shoot MRP-70.9 with 117 Hornady SPTBT into 3/8" groups. Now it sprays them into 2.5" groups.
It still likes the MRP-70.5 with 115 Barnes TSX though. Just shot a group today into .7grp.
I just gave it the David Tubbs abrasive bullet treatment to try and smooth out the bore and get it to shoot better. No such luck. In fact I think I screwed up. When I look into the barrel, from the action, I see very faint evidence of rifling. It did not look so worn before the treatment. When I look down the bore of my newer .300Wby, I see substantial rifling. On the bright side, it does clean up easier. Would I do the treatment again, No!

Regardless, I think a new barrel will be getting ordered soon.
Other than the stated problems with this rifle I love it and the caliber. It weighs in at 6.7 lbs without scope and is perfect for hunting deer in steep country. I also love the Weatherby stocks. The angle on the cheek piece goes down so when it kicks it goes down and away from your face. The comb lines my eye up perfectly with the scope. I guess I might as well throw in the fact that I really like the Zeiss conquest scopes as well. Very sharp and clear, not too heavy and bulky and competitively priced with Leupolds. The only thing I regret is not getting the turret knobs on the 3 - 9 x 40. I did get them on my 4.5 - 14 x 44 for my 300Wby and I love it.
