Allen....now I'm gonna do the "switcheroo" on you. I didn't know it was a wby ultralight. I REALLY HOPE it's not an early one as the first year or two of production they were really really crappy shooters. I and a bunch of friends got some of those guns and we all had trouble getting them to shoot.
I was about to get a re-barrel job as NOTHING WAS SHOOTING in that gun from 165-200's with all the popular powders. Then along came retumbo. In my gun 86 of retumbo under 200 accubonds was decent. Then I tried the 180tsx and worked up to just over 88 grains and......whoohoo....a gun that wasn't shooting better than 6" groups at 200 yds was now shooting 2"/300 yds. I have never ever seen a gun that couldn't shoot anything behave so much with another powder but it was a miracle. Anyhow..if you have a later model gun I think they have perfected them alot and you hopefully won't have trouble. Let us know how it goes....the balance and feel of the UL is wonderful.
