I am one and I do my own gunsmithing.
I have a Springfield 1903-A03 and its action and trigger are far better than the carbine that Oswald used. It takes me 5-6 seconds to get past the creep to squeeze off one accurate shot - meaning 5-6 minute accuracy which is about what Kennedy was hit with.
PS - and I do know what Im talking about - I do half minute with iron sites, small bore at 100yds prone.
