Hey amigo.............said what I said as a general reply. OK, I see now that it tailed under previous posts. Not a personal diatribe. It seems that we are a might touchy about "condemning someone etc etc". As I said, no offense meant and if you can find it in your heart, please forgive me.
Not having any first hand knowledge of your wares am in no way stating their worth or lack thereof or maligning their ability to align............in a vertical plane.
What I did mention was that the Burris Sigs allow for windage as well as vertical. The Hawkes being one piece would indeed keep the rings on the same plane - vertically and that's a good thing. Still a potentially partial fix should there be a windage "situation" that needs more correction than the user would want to crank into his scope - with the idea of centering up the erector tube within the outer tube, i.e. windage.
Yes "ve haf vays" of correcting windage, starting with the ring, depending on type by shimming one side or the other. I'd probably set it up in the mill, indicate true in relation to the base, mount the rings, indicate to same surface on front and back (the inner surface as the outer is immaterial and everything has a mfrg tolerance). A lot of fun for those who have access to the equipment and very time consuming.
Was mounting a Bushie 4200 last w/e and did NOT have my fav rings. Had some Redfields iirc that had a screw on both sides so the chance for error was great in windage misalignment. I bottomed ea screw on one side and backed off exactly two turns - the threads being a fine enought pitch that it should bring me within a couple of thou of being equal. Shot my Izzy 46M for groups/pellet likes. Trust me, I didn't crank the tube tight in the rings even though I felt reasonably secure with my methodology. Being an SSP, my concerns were minimal re recoil and scope movement.
Some BR folks like to lap their rings, and shoot for 70+% contact. To each his own. However, paying $35-45 for a set of rings with inserts, does away with shimming. Now, shimming. How many have shim stock at the ready? You know, .001, .002, .005 etc etc? I can make bolts all day but it sure is cheaper to go to the hardware store and buy'em by the sack. Same with diddling around with pop cans, tape that compresses, plastic or stainless shim stock and then only knowing if things are truly aligned by using an indicator either before to know how much shim stock is required or afterward hoping that what is put in is enough.
As I said, the inserts, a gimbal mount principle just don't care about no steenking .015"..............the tube is securely, and lovingly embraced, never to be marred even when my calcs may have been off .010 or more for the remedy. I've never marred a scope yet and hope I don't thru mental error..........cause that's what it will be, not the rings I use.
Now for a freebie for those who don't know this l'il trick. To help prevent the scope from moving under recoil with regular rings, take ye olde Scotch type clear tape and line the rings and razor off the excess. Just something an old BR shooter passed on.
