I have a 6mm(.243) I built with a take off .244 barrel that gets 1-1/4 groups on a bad day with 100 grain RN. That is really saying something with a .244 twist rate. Sell it before you sink a million into it.
Yes, that is harmonics tweaking the barrel. With this gun you cant do anything with that because its a break action type. Actually I lied, you can take off the forearm and shoot supporting just the action. But its impossibe to bed anything on it. Just for s#$t and giggles I am going to lap the barrel, have it recrowned, check the reciever for lockup squarness and load new ammo. All cheap things to do (buddies a g-smith) I bet I can get it down to 1 1/2 or less @ 100yrds.
