I have a S&W 67 , 38 special. I like the gun a lot, but sometimes I want a little more horse power. Would it be safe to rechamber to 357 Mag.??? I've heard if you want a Mag, buy a Mag, [ I have a Colt Trooper 6", Taurus 605 3", and Winchester 94 Trapper]. 99.5 % of my shooting is with very mild 158 RF lead bullets, but the other 0.5 % I like 180 gr. with lots of 2400 or H110 behind it. The S&W K frame is chambered for 357 { M66, M65, etc.} Will my M67 stand the pressure?<!--emo&???--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'><!--endemo-->
