Hi Porker,
Nice job on the hook.
You've reminded me that I've forgotten to remind myself to make a butt-hook (it may have a different name in the US!) for my old Anschutz .22 target rifle. The one on it now is a casting, unadjustable except for moving the whole thing up and down. Though OK for the standing and kneeling leagues, it hasn't got quite the right bend on it, in the horizonal plane, for when I'm shooting prone. And, due to wear and tear on the knees, I don't do much S&K now.
