That should work fine.

I can't agree with that assessment.

The VV data I have lists a min/max of 5.2 to 6.0 grains of 3N37 with a lead bullet of that weight. So you will be starting out only a little below the middle of the recommendation with a magnum primer. If you insist on using a magnum primer, I would definitely start at the minimum recommended load. When you are working with a small volume high pressure cartridge like a 9MM, you need to proceed with caution when going against the norm.

my data

my new (2 days old from vv starts @ 5.4 gr. to 5.9 for 124 gr. i found another entry after searching primers and have learned that a mag primer will add about 1 gr. to your load. so right now i think i will just wait and buy regular small pistol primers to avoid any problems. i need to clean up my lee mold any as there dropping at .357 to .358 (tl356-124-tc) as i expected there running about 120 gr. with ww's.
better to be safe and still have hands and eyes to shoot tomorrow.

"... i think i will just wait and buy regular small pistol primers to avoid any problems."

Good move.

My mistake, and a good catch Mal. I missed the fact that the primers initially asked about were magnum primers. I ASSuMEd in my quick read that they were standard primers. Sorry all.

experience

If your bullets actually weigh around 120g your proposed CCI550 / 120g cast / 5.5g 3N37 load is fine.
I often use CCI550's under 3N37 in 9x19 to aid in avoiding primer flow.
E-mail direct for further discussion.
