Primers
« on: August 12, 2012, 03:55:45 PM »
primers are becoming difficult to find at a decent price where I live and I can't find anyone where I live  to make a bulk purchase from an online dist.  Quite a few years ago, I must have gone wild and bought a bunch of CCI LP Mag. primers and have >2000.
I only reload for my redhawk  and will keep a few hundred in reserve.
I am seeking advice about using them in my 10s. I am thinking that they could be used safely but I would like to receive some feed back concerning this.
Any warnings-advice-use during cooler weather-or what ever
I am thinking from what I have read that it would not be dangerous and would not show much if any velocity gain or really anything to justify the extra cost.
Will probably use with Blue Dot in my 1006 & 610 w/ a charge not greater than 9 grs under 180 hardcast.

Any feed back appreciated

Jim

I do use magnum primers with some of my 10mm loadings, drop back a 2 tenths on some loads, some I use directly.  You can tailor a load to use them.

I most use CCI 300's.  But, I will say that especially light loads of Blue Dot burn better with magnum primers.

It depends a lot on the powder you will be using.  Blue Dot and slower, no problem.  Faster than that, be very careful.  Some powders are NOT mag-primer friendly.  However, with no more info, I'd suggest backing the load down by 10%, rather than specific grains, and work up.

Mag primers are not ideal for 10mm auto, but they will work for the slower-burning powders. As an example, Accurate no. 9 agrees just fine with mag primers. Speer had published loads calling for mag primers. I actually have a couple of pet loads with CCI 350s and Accurate no. 9.

As with any load, just start at the starting load, if not a couple tenths less, and work up carefully. I would not load to max book data with mag primers if standard primers are called for.
