Always clean from the chamber end and you should be OK without a boreguide. Try your gun for groups with and without an o-ring to free float the barrel to see which your particular gun prefers. Do not overtighten the forearm screw and try to rest the gun on the sand bags (or whatever, avoid hard objects to rest the gun on) just foreward of the trigger guard, by the action hinge pin and squeeze the trigger, being sure to pull it all the way through and completely to the rear. Remember be consistant, be safe and have fun, thats what it's all about....<><.... :grin:
