Growr and I shot a action pistol match in Miles City, MT about 2 years ago. We are child hood friends from the same home town. BTW, he beat the pants off me.

He has a 625 JM and I have a 625 JM Performance Center. Differences, cylinder length, under-lug differences, & how they cut the rifling. JM is ECM (Electro Chemical Machining) and the Performance Center is Deep Cut Broached Rifling.

I haven't had a whole lot of leading problems with cast (home brewed or commercial). But they are pretty dirty and a lot of smoke due to the lube. Great for practice. Haven't tried plated or coated yet as for the cost I can get Zero FMJ 230 gr. for the same price. No problems with them. I do have a friend here that gets me a dealer discount.
