Finally was able to get out to Chabot Sunday.
Had a couple others to sort out and thought to bring my 10/22.
It has a Volquartsen barrel and my trigger job, bolt upgrade (includes grinding to .044" head space and radius rear for smooth action) bedded in an old stock of unknown manufacture. Bolt release mod and a Volquartsen Exact Edge extractor. Made my own 20MOA scope base too. Uses my own set screw V-block, Allen take down bolt and my extended mag release. When bedding, I in-letted a tight fitting aluminum insert for the takedown bolt that acts like a piller to dampen movement.
Put on a Barska 10-40 x 50 and used a lead sled.
SK Standard Plus ammo.
I did measure rim thickness and grouped in boxes that all were within .0005".
Did notice small impact change when going from extreme measurements.
50 yards scoped.
Calguns target 10:22 - 11:11:12.pdf
A couple are close to the edge but do touch and I can mail original target if asked.
