[QUOTE="James Jones, post: 181073, member: 8843"] Well think about it ,if the natural curve of the barrel is to the left then the bullet is getting started that way and that will only increase with range and theoreticaly speeking if the barrel is indexed pointing to the left then the windage is gonna be differant to one side than the other :eek: and thats gonna suck trying to find a dope sheep out on that one. I think that you would be supprised at the amount of guys that build accurate rifles for a living that are not concerned at all with this , especialt target shooters as their target is gonna be at prepositioned ranges each time and only the windage has to be adjusted most of the time. On all of the guns I have built I indexed the barrel with the curve pointing up just because I feel that little extra is worth worrying about. I have only heard one other gun builder that has mentioned this and thats Nathen Dagley ,this is a big reason that I endorse him whole heartedly as these small attentions to detail all apy off. With the Savage its not that hard to install a barrel with it being indexed cuve up , as long as the chamber is not finished cut. The two i did with the barrel nut I installed the barrel so that with the nut snug and the curve up the bolt would just close , the barrel and action were then both whitness marked for the reinstall , the barrel was pulled and then reamed just like you would with a conventionaly shouldered barrel , one of these was done iwht a pull through reamer that worked realy well , it takes two people , one to turn the reamer and one to apply pressure to the reamer with the bolt. Once the bolt closes the reamer is turned with no pressure on the closed bolt till it turns freely , generaly about on revolution. is each case the chambers were cut to the tight side of min spec so that they would just get snug the last 10% of the bolt closing.
