It may very well be that the easiest/best fix will be to use BH209. Knowing how you detest the powder, makes me hope it is the best fix!

You may be right
Ron. My brother-in-law's full length Omega sure shoots lights out with 110 grains of BH and Barnes XPBs. I guess I'll give the premium route a try.
Do you have a consensus as to whether the rifle shoots just as good or better without the QLA?
So far
Bronko I think it's shrinking the groups a tad - maybe 3/4" or so. Anything under 2" for five shots at 100 yards is perfectly satisfactory. But you know how it is. I'm forever in pursuit of that 1 MOA group.
