JG,
The smith lapped the TLWs on the last build I did with a Borden action as well. If he wouldn't have, I would've prior to mounting the Swaro. After my first encounters w/ TLWs putting the mentioned pinch marks on two scopes, I've lapped every set. Not to mention how out of line many have been. And then you mention HCR bedding them as well. I haven't bedded any yet, but I have seen gaps under some sets. I didn't bed as they seemed to have enough bearing surface and held fine.
I really don't like them on Tikkas since it's a flat on flat approach. If you barely snug them, they have a lot of side to side play for terrible alignment, so it's key to align them properly prior to torqing.
You wouldn't think 17inlbs would pinch the tube, but the lever effect is pressing the pivot in. Lapping seems to negate that effect.
I don't doubt folks get by without issues(IE JB's comment), but it's silly to think it doesn't happen.
Have a good one,
loder
