I did double check and my 200gr lead RN load with Unique is 3.4gr ... this within a Lee published load - max load is higher. I dont understand the reason why large bullets freak people out when it comes to the 38 Spl? I have never had any trouble shooting 170-200 gr 38 jacketed or lead reloads.
I load 200gr lead round nose in 38 Special for IDPA competition - 200gr is the old Police/FBI bullet of choice ... Magnus bullet company in Alabama sells pre lubed 38/357 200gr bullets for about $45 per 500.
Lee has reloading data for 200 gr lead (I use Unique powder). At 550 fps my light load...
I think the 686-4 is from the early to mid 90's? The yoke head and screw on this gun are the 45 degree type - this not the spring pin type of retention screw system with a "flat" yoke head that I think came later.
I know there are a couple/few different type of yoke heads/screw types in...
S&W 686-4 yoke failure picture - yoke screw actually cut through the yoke from IDPA aggressive reloads (Safariland comp 3 speedloaders).
The yoke will now come off the frame with the yoke screw tight in place (cylinder open)
Anyone seen something like this before?
