[QUOTE="sable tireur, post: 1014930, member: 27307"] merbeau, Under normal circumstances I replace the original barrel with a higher quality custom barrel. Yes, it's more money and slightly more time but I am confident that you as a client is getting the best available product installed. As you state, it is possible that the second factory barrel will not shoot up to your expectations. On the other hand, it might be just fine. Remove the original barrel and clean the donor action thoroughly. The threads will need attention for sure. Clean the threads on the second barrel then check the headspace on the numbers derived from the action, bolt and recoil lug. Adjust headspace as necessary to also include the timing of the sights and roll marks for proper alignment. Be aware that most if not all gunsmiths will recommend 'blueprinting' the action. Here the problem will be the threads since some gunsmiths use the +10 (thousandths) oversize thread tap which negates using the second factory barrel. Replacing an original barrel with another factory barrel is usually a wash for accuracy and no guarantee but it will cost you money anyway. Why invest in a lateral move when you can have a new custom barrel with an accuracy guarantee? This will also allow for having the action blueprinted and the custom barrel threaded for the re-cut threads in the action. Yes it will cost more money but you will have an outstanding semi-custom rifle. Regards. [/QUOTE]
