The new BVSS has been coming through. Had to do a little tweeking as the front pillar was not in contact with the action and the screws were torqued in at about 15 in. lb. The first groups were not very pleasing at 1.250 out to 1.600.
After setting up the pillar properly and re-torquing I was able to reduce the group size to .526" with 5 shot groups.
Checking the tang I noticed it was contacting the stock so I removed the action again and added clearance about .003" and torqued up the action at 35 in.lbs. and ran some loads thru it again. It groups 5 at .330
Running about 2915 fps with 69 gr Noslers Comp and 24.5 gr Varget. I set the bullet back at .005" from the lands. Its starting to look like a keeper.
