i have been told it is not safe to rebore a .38 special K frame smith and wesson cylinder to .357M due to the higher SAAMI pressure rating of the later.
not having both in hand, i think the K frame 357 and 38 cylinders are equal diameter and chamber wall thickness. i also think a K frame has the same dimensions and metal thickness inside and out from OEM S&W offerings in either caliber.
i am not sure about overall cylinder length, but same could be accommodated for by shortening the forcing cone/bbl extension inside the frame's cylinder opening.
can any of you offer up hard copy proof, not speculation, that this is true/untrue?
i have the speculation part covered already.
thanks in advance,
gunnie
