38spl Distinguished Service Ammo

I expect that this has already been debated to death - I am lazy to trawl through a search - sorry.

Happened that I got into a debate about bullets today so I searched the latest version of the NRA Rule Book and grabbed the relevant text. [size=13]158gr RN or SWC bullets (but, interestingly, it does not specifically mention lead - can we use158gr jacketed 357 bullets?):-[/size]

[size=13]P9 ■ 2020 NRA PRECISION PISTOL RULEBOOK[/size]

[size=13] 3.3 Distinguished Revolver - The revolver must be capable of chambering and firing a 158-grain round nose or Semi-Wadcutter .38 Special cartridge. It must be a factory manufactured revolver with no external modifications except for stocks which may be modified or changed because of the size of the competitor’s hand or to facilitate loading. Except for stocks and the honing of the sear or sear notch to make a more crisp trigger, and maintain a 2 1/2 lb. minimum trigger pull, no external or internal modification may be made to the revolver as manufactured and sold by the factory of origin. No parts may be removed from the revolver, either externally or internally, nor may any part be added, with the exception of milling the cylinder to accommodate moon clips. Specifically prohibited is any system of recoil control based upon compensators, barrel venting, barrel porting or weighted grips. Exposed holes that have been drilled and tapped for mounting of a scope are not considered to be an external modification. [/size]
