Like I said check the # for the heat treating process, by the way the # are different for the different manufactures Springfield 800,000 or higher, the double heat treated between 800,000 and 1,275,767 are best safety and for smoothness. Remingtons as S.B. said are OK but not as smooth unless worked on. Rock Island Springfields under 285,507 should also be left alone. And forget any by L.C.Smith as though safe the workmanship is poor. Good rule of thumb is do not use a 1903 with a # under 800,000 One other point which S.B. made and I left out is DO NOT cut up a rifle that is in original condition. You can sell it to a collector and get at least enough to buy your barrel and a butcher job to strip for an action.
With nearly 5,000,000 Springfields made it is easy to stay away from the low # ones. Like I said there is no problem with the Springfield for your project just stay over 800,000 or go with a Remington which will be well higher then the 800,000 # since they start in the 3,000,000 range.
Sorry if I was not clear I should have said it is not hard to find a safe Springfield not that there is not much to this.
