Alliant
Power Pistol and Vihtavuori
N350; be very very careful.
Use new sized cases ONLY; I recommend
IMI.
Use
CCI300.
Use the longest OAL that functions perfectly every time.
Install a minimum-weight recoil spring of 18.5lb.
I suggest the 230g lead bullet come from
www.PennBullets.com
Using a
chronograph, carefully map your loads using .2g increments, watching for a loss of linearity.
CAUTION: extreme ammunition will increase wear and decrease service life.
