I know the guy that posted these results and talked with him regarding them.
The first thing that I would let any potential Bergara buyers and curiosity seekers know is this...
- the shooter only had 1 lot of Tenex and a half hour at the range before it got dark. Therefore, no ammo or lot testing yet. Also, he didn't have time to tune action screw torque.
- Not knowing what headspace is set at in these rifles, but assuming that it's within either SAAMI or CIP spec in order to cover their rearends for saftey sake, the tightest that it could possibly be is .043", but more likely .044" to .045". With that said, Eley is probably the wrong ammo for that rifle. Lapua/Sk will likely shoot better as the rim thickness will better fill the headspace.
To sum up, between tuning action screw torque, increasing rim thickness through a different ammo choice, and lot testing that ammo, I would guess that those groups will shrink significantly.
What I'd really like to see are pictures of these mythical $2000.00 Vudoo rifles that have been mentioned over and over in this thread. Oh, and a link to where one can be purchased would be helpful as well.. ?
