So... took my new HP out for a first day workout, inspection, breakin, etc.
Fired 100 of Curt Thomas's IPSC match loads (180 gr. truncated cone) through it at about 20 yards. "Groups", if you can call them that, were on the order of 8". I've known Curt casually through PPC competition for about fifteen years or so, and I know his quality control is pretty good.
Looking at the cardboard PPC target, both Bill Leeper and myself felt that the bullet holes showed evidence of keyholing. Keyholing in a factory new pistol? Some 180 gr. lead SWC loads wouldn't even feed with a full magazine - and showed equally pathetic grouping ability, even if it was a load straight out of the book, no load development.
Before I freak out here, has anybody else heard of similar problems with a new .40 S&W Hi Power? The keyholing appearance I can't figure out - 180 gr. bullets should stabilize just fine in a factory .40 S&W barrel.
Getting nervous here... btw, I slugged the barrel with Cerrosafe and Bill miked it at .404" bore diameter. Little big, but nothing that should cause these kinds of problems. Visual inspection of the barrel is that it looks clean, no bulges, jugs, etc - looks new, which of course it is.
Ideas? Thoughts? Prior experiences? My previous Hi Power in 9mm was very accurate... my confidence is shaken.
