On another forum I was told that the K frame Smiths were subject to forcing cone damage with high velocity, light weight bullets.
It seems that when the Model 19 was introduced police departments favored the magnum loads with 125 grain bullets. Turns out the magnum 125s hit the forcing cone faster than heavier bullets and thus destroyed the forcing cones.
So Smith said to only use 158 grain mags since they start slower.
My current favorite load is a 125 grain plated bullet ahead of 8.0 grains Unique which gives me only plus P velocities. I think. I've never actually clocked it.
My question: if I'm using 125 gr plated bullets (note: that's softer than jacketed) at plus P velocities, that shouldn't produce the same damage as full-charge magnum bullets, should it?
#2: How many rounds of full-charge magnum ammo does it take to destroy the forcing cone?
#3: If it's the velocity + light bullet that kills the 19, then why isn't this a factor in the N frames?
thanx.
