Hammer forged & button rifling vs cut rifling
Both hammer forging and button rifling methods cold work the barrel steel and therefore induce compressive stresses in the barrels while displacing metal into lands and grooves. A subsequent stress relief before machining the barrel profile should reduce the stresses.
Cut or broaching methods, while lacking the continuous grain flow around lands and grooves of the above methods, do not induce stresses
into the finished barrel. Blanks should be stress relieved before drilling & rifling and after straightening.
A barrel with internal stresses will drift when it's hot.

Thanks for the information V35, always find something on this forum that I didn't know. 0 -
So what's the verdict? I hear people saying that cut or button rifling is more accurate. This I can't see being posible as my Sendero has a SS hammer forged barrel which has effectively outshot any of the production guns I have put it up against. The only ones I have outshot it with, are custom stainless barrels cut by an extremely adept gunsmith.
A great rifle with a junk scope,....is junk.0
