Re: New Purchase
Rob: No, I don't loosen. And as long as the paint indexing at the head doesn't change (it's indexed on both sides), I am not worried about breaking screws, either. If the head starts moving and the tip stays put... I know I have a problem.
But that is a very good point especially for folks running their screws close to the limits!
That said, about once a year, everything comes apart and gets checked. In fact... I am due in about a month before I leave on vacation...
Also, never broken a screw or had a ring slip. My POI also never moves. But all are possible if you over- or under-torque. That's why it's important to do it right and use a good tool.
For the folks mentioning 65 in/lbs. That's a pretty standard recommendation, but is just that -- a recommendation. And every maker has their own recommendation. My Ken Farrell rings/base recommend 50. I go a couple of pounds low. Other makers recommend more or less, depending on the design.
And with a light-recoiling .308 -- a heavyweight one at that -- combined with wide 4-screw rings that have a lot of bearing area, my torques are more than adequate.
As someone above said, YMMV. Know 'your' gear because the numbers for mine aren't the numbers for yours aren't the numbers for Rob01's.
My point in posting is to show some ideas for keeping tabs on your screws and for keeping your numbers straight.
Cheers and good points all.
