Just been out and fired the first shots though my rifle and while it was only fireforming loads with the 316-299 over 13.5gn Green Dot (roughly 1400fps) and shot at 35yds as I didn't know how the aperture and new front sight I made was going to calibrate but this is a 10 shot group from standing with the bog-pod. With a quick calculation shows I can get by with a .006 shim between the sight arm and the rifle wrist. I little touch with a file will lift it but I will wait till I get the new mould and a decent bullet and settle on a hunting load till I finalise that. Very happy so far and this is with a bullet that has no nose support - 304 nose in 306 bore.
