Question about shotgun primer

Jim Partlow · 08-02-2013, 10:42 PM

I'm trying to load some low pressure 16 gauge shells. Fed hull,
BPSG-16 wad, Rem primer, 7/8oz shot, 21 grains 7625 powder.
My question: I was able to gather all the Componets except rem
Primers. I know it is a big no no to substitute Componets, but is
There a safe substitute for Rem primer? I have CCI 209s and Win
209s. Any help would be appreciated . Jim P.

I don't worry about primer brand, because the loads we shoot in these old guns are very soft. but a have found accuracy problems in rifles

Thanks for the reply Paul. In my research, I found that a
Primer change can effect pressure as much as 2000 psi. Just
Want to be as safe as possible. Jim P.

use the winchester 209 primer.. charlie

Do you know how much that will raise pressure? Jim P

Jim, I substitute the Winchester 209 for the Remington 209 with no noticible increase in pressure. I have a chart around here somewhere from Tom Armbrust that show's the primers are almost equal pressure wise. And besides the Winchesters are cheaper..

On this one I have to disagree with Charlie. I'd pick the CCI if low pressure is the goal. Win 209 are always a bit hotter than the rest. Not so much that you'd get into pressure trouble, but if you have CCI primers, why not keep things as low as you can?

Here's the link to the Armbrust Primer testing:

Thanks for the input. I did read the Armbrust Primer testing article, and
From what I gathered the CCI would be lower pressure.
I've also thought about reducing shot charge
To 3/4. I believe that would also reduce pressure
significantly. Two of the guns I plan to shoot
With this load have Damascus barrels. I figure
The lower the better. Jim P

The crimp depth chart caught my attention , I am thinking your spacer (when loading 2.5's) should be given a good bit of consideration. Maybe a little more than your primer choice?
