I think I've finally settled on a load for this gun.
Powder: 48.5 grains of Reloader 22
Bullet: Berger 105gr VLD
Primer: CCI 200
Velocity is right around 3300fps
Group at 300yds from a bipod off of a shooting bench (a wee bit bouncy!)
I have been shooting 49.0 grains, but have been running into problems with temperature and this load just shoots too good to mess with.
