Anyone shoot heavy bullets in .357 mag?

I picked up a box of 200 grain truncated point cast bullets at a gun show a while back to try in my Model 28. I wanted about 950 fps from the 4" barrel for an easy-shooting load with good penetration. Started with 9.0 grains of 2400 and got a surprise. According to my old Lyman manual, I was expecting about 850 fps. Six rounds over my Chrony averaged 995 fps. Mild recoil, primers looked good, and the cases fell out of the chambers. I quit while I was ahead.

These bullets have a good 5/8" bearing surface, and the base is 1/2 inch deep in the case when seated. I'm figuring that to run the pressures up even with a mild charge.

Anyone else have experience with 2400 and heavy bullets in the .357?
