    LOL Doug, had to read that 3 times!

    The bolt rotation is built into the lug design, to change that means a new receiver and bolt with the desired lugs . . . thatĎs building a whole new gun with a different receiver complete with all new paperwork even. So nope, U B stuck with what U got.

    Nah, just chop off half of each locking lug, then the bolt will open sooner. Problem solved, right?

    New niche market! Send your weary 90 degree bolts for a quick trimming. Shorter bolt throw and also think of the weight savings!

    Heck why stop at half? Grind them clean off and have yourself a high dollar German stile straight pull bolt, save yourself thousands!!

    I reckon my question to the OP would be what problem, if any, is he experiencing that causes him to ask the question?

    Those who know more about the subject, than I, have chosen to joke about your question. Theyíve answered it, but didnít really explain.

    Someone can correct ME if I'm wrong.

    Iíve noticed that Bolt Actions with shorter than 90 degree bolt lifts are ones that have both multiple, and smaller locking lugs, as in 3 or even 9.

    There is apparently, and amount of locking lug surface required to handle the required pressure, and 2 opposing locking lugs of needed size, necessitates a 90 degree turn to lock/unlock.

    Changing from 90 to 60 degrees would seem to involve a MAJOR redesign of an action.

    And, the difference in bolt lift is not considered to be a MAJOR advantage.

    So, maybe you can see why, the humor.

    Yup Smitty thatís pretty much the deal, takes a total re-think of the lug design.

    I donít think you ďneedĒ all the lug area on a on a bolt action to hold the normal pressure. There are other action types that use a lot less lug, take a gander at an M1 for instance. But remember if the lugs fail on a bolt action you'll be stopping that thing with your face where the other designs have something between your face and the back of the bolt. So with the lugs as your only protection . . . you want them to be way overkill strong, no chance of the blot comming back at the shooter ever.

    If you aren't worried about keeping weight down you may find a tactical bolt handle solves your clearance issue.

    OK, what kind of rifle do you have. A change of bolt throw may solve a scope clearance issue, just changes hand location while operating the bolt. There maybe a solution however, what kind of scope you using.

    Don't grab the bolt with your fingers, use the palm of your hand to lift, open and close the bolt.

    My dad left me his Argentine Mauser that the bolt would strike the scope. My solution was to replace the rings and raise the scope. Its on a thumb hole stock and was sitting too low anyway. Now there's clearance for the bolt and its more comfortable to shoulder and sight in.

    Right. I was gonna suggest a higher mounted scope.

    Most scopes are mounted too low anyway, and you hafta hug the stock too tight, and FACE the Recoil.
