RE: 7mmstw v. 7mm ultrmag
Stubblejumper,
I was discussing some of the things you were talking about with my gunsmith, but regarding the 300 Ultra. I had read some posts from a few months back about some guys critising the 300 ultra and talking about how inaccurate they were. Some of the guys were blaming the round. After discussing this with my gunsmith, he was saying people are to quick to blame a round. That in his opinion it comes down to the rifle. I think why you were seeing good results on multiple loads was that you had a custom rifle. Not doubting your ability to handload good, but if your gunsmith who blueprinted the action and rebarreled the gun for you was any good then you should have no problem shooting any quality bullet with 1/2" accuracy.
