Im as non-competive as they come; not a club member or a re-loader but I have a Ferret 36" SS, .50 BMG upper with Ferret's 1lb trigger dropped into my lower.
She groups around 1 MOA with surplus, a bit better with 750 gr. Amax loads.
Dave over at Spider Firearms was a tremendous help to a .50 noob like myself when it came time to select chamber/barrel length/etc.
Pleasure and an education to deal with.
Maintaining a constant state of cat-like readiness and a heightened state of suspicious alertness.
