New Colt King Cobra's and lead?

I somehow missed this post when the OP first put it up. I have shot several hundred .38 SPL 148 grain DEWCs and 158 gr LSWCs through my KC with zero problem, quite good accuracy. I'm no longer reloading these days.

They're sure attractive. I need a set of pin gauges still but the one I saw at the shop felt great and looked even better.

Been firing 158 gr LSWC through mine just fine.
Some of them have been near 1,000fps. which is a "Medium Magnum" class round out of the 3" KC.
No leading to speak of. Brinell is around 17 on these.

I always fire a wheel or 2 of warm magnums at the end of each range session, out of habit.
These contain jacketed 158gr bullets and are loaded with 16.5gr. Of WIN 296.
I seem to believe these rounds "clean" up the barrel and cylinders of any lead or lube residue.... I think it works.
