Please explain the difference in barrel manufacture

[longwinters]

Please explain the difference in "button rifle", "cold hammer forged" and perhaps any other method of barrel making.

Thanks,

Long

With button rifling they push a "button" through the bore.   That button has the rifling pattern around its circumference and it impresses the lands and grooves into the bore.  Hammerforging is done by placing a mandrel with the lands and grooves on it into the blank barrel and pounding (hammering) the the barrel down onto the mandrel, impressing the rifling into the bore.  Rifling is also cut into barrels.  This involves actual removal of metal to form lands and grooves.  The other two do not.

thanks for the info CB.  Is one method actually better than the others or is it a preference deal?

Is a  Chevy better than a Ford?? It's likely more personnal preference. I believe(without empirical data of course) that cut rifled barrels are less likely to warp as they heat. But of course if the button rifled and forge barrels are properly stress relieved....... Very high quality and very very accurate barrels are made from all the methods.. Could be the care and quality of manufacture is more important than the technique.
