Scott, right now I am assuming they were shooting accurately because of the success shooting the clay targets. And I am assuming I had the velocity that I wanted.
What does puzzle me somewhat is the 50-325 are slightly smaller in diameter than are the 275's either the XPB's or the Expanders, because of this even with the knurling they really fit loose. I was not concerned that they would come off the load unless I jarred the rifle pretty heavily.
Anyway I was really surprised that it appears that I did get stabilization with the bullets actually both of them.
I would say that at this point - I would hunt with them but more testing would be required. The other problem is I really do prefer the conventional sabot/bullet. The reason I even got this bug was that Idaho requires a full bore lead conical for ML season. I am hoping at some in the near future that Idaho will loosen a bit and continue to require full bore, but because of the impending 'lead ban' controversy they might allow bullets like the Thor or FPB. I think that might happen before they allow a sabot/projectile again.
I am hoping and thinking the Lehigh might be just slightly larger than the Barnes and not require knurling at all...
