How fast are you pushing that coated lead bullet?

I don't have a chronograph. I would guess that 15.1gr of powder should run them at around 1200 from a 4 inch barrel. I have loaded them hotter with up to 15.6gr but accuracy seemed a better at the lower charge and more just uses more powder and makes more recoil. The bullets did not create any problems at the higher level, no leading or anything

IIRC, you are supposed to treat coated lead the same way as plated - 1200 max; or so I have been led to believe. I know from shotgun, rifle and handgun, slower loads typically produce the best results over maxed-out hot ones.

That's the beauty of 357mag revolvers you can load up 38spl's or 357mag's for them. When I first started out shooting the 357mag revolver was my favorite and still is one of my favorites replaced by the 45colt/45acp. My first revolver was a colt diamonback and then a colt python, boy how i wished I kept them.$$$$$$$

I sent an email to the guy that makes the bullets I am using to see if I should limit them to 1200fps. This is his reply:

I have shot a good bit of 125 gr 9mm out of a PCC carbine at 1500fps just to see how the coating holds up. For me shooting 100 shot groups I had no buildup in the barrel. The groups did not open up and the gun was very clean after shooting them, just like jacketed. I have customers shooting them in IHMSA 44 mags at 1400fps and USPSA race guns at 1350+. No far no complaints.

I used all the 158gr bullets I had until Monday, when another 1500 should arrive. Today I loaded 100 of my coated 130gr bullets. I used 7.4gr of Unique and a magnum primer. I usually load these with 7.5gr and a regular small pistol primer. I load these to shoot in my lighter revolvers like my 3" model 60 & SP101. These hit pretty close to the same point as my 158gr load with my adjustable sight revolvers

Had time this afternoon between other tasks so I loaded another 100 if my 130gr loads for 357 magnum

That’s enough of these for now. Got a 62 pound box of bullets the other day so I have more 158gr magnums to load.
