[QUOTE="tobnpr, post: 2820023, member: 68758"] Hard to tell on that, no specs on the hardware. Mine is shop made, with 7/8" threaded rod- all grade 8 (which is critical) including n&w. If you're pulling the "toughest" barrels, you need clamping force (notwithstanding whatever the poster above has in mind) and surface area contact on the barrel- and you need the hardware that can withstand you tightening the nuts with a 3 or 4 foot cheater pipe. You can have 2 tons of clamping force, but if you're only contacting a small surface of the barrel it's going to slip. Obviously if the barrel has a few inches of straight cylinder/no taper at the shank it's easy-peasy. Some sporter contours like the Tikka have no cylinder- it's tapered from the receiver ring forward and these are the toughest. I either machine/bore a custom bushing or push the easy button and take a blank bushing and use Devcon 10110 putty to mold the contour inside the bushing. What I don't like about the one above is it uses proprietary bushings- no idea why they're not simply round and have that strange protrusion on them. It ain't the bushing that slips when pulling a barrel. [/QUOTE]
