Recipe question

[magicchip]

I have a box of win magnum small pistol primers I lying around. I figured I'll use it.
The only problem is I use regular primers and have no recpes for magnum primers.
Anyone have good recipes for 9mm and 40 using mag primer and unique?
(124 grn lead for the 9mm, 180 grn plated for the 40s&w)
Thanks.

I have used magnum primers in my 9mm when regular primers were not available and did not have any problems at all. However, I am not saying that this is perfectly safe to do, it worked for me though. You can use listed data in your manual, just start at minimum load and work up from there. This is the way I have done it. If you used an X amount of powder with a regular primer, do not use that same amount with a magnum primer to start with. Make sure you start with minimum listed load and work up slowly watching for any possible signs of pressure.
