.32 H&R magnum - any good reason NOT to use non-magnum primer?

[W.E.G.]

I'm loading jacketed bullets.

100-grain and 115-grain.

Using Winchester 231 and Unique powders.

Powder charges will be warmish, not hot or atomic.
I'm aiming for something in the 20,000 psi range.
Quickload lists the max-pressure for .32 H&R mag as 23,496.
(.38 Special being 17,000 psi max)


To be fired in a Ruger Single-Six revolver.

I have 2000 standard small pistol primers already on hand.
I'd need to spend a couple hours in the car, and spend more money, to pick up some magnum small
pistol primers. Not that I couldn't use a reason to get out of the house, but I'd rather use my stock on
hand unless there is a really good reason to not use the standard primers.

I have found James Calhoon's primer thickness chart to be very helpful for RIFLE primer choices.
http://www.jamescalhoon.com/primers_and_pressure.php
Calhoon mentions that pistol primers are 0.017" thick, but curiously does not differentiate
small-standard-pistol and small-magnum-pistol.



Quickload only leaves me scratching my head too.


I don't think 231 or Unique fall into the "difficult to ignite" category.

My real concern is that I do not want any PIERCED primers.

Maybe I should just use standard small rifle primers.
At 0.020" cup thickness, I would be thicker than Calhoons 0.017" number for pistol primers.
I'll venture that the Ruger strikes hard enough to reliably ignite the 0.020" primer.

I use standard Winchester small pistol primers for 327 Federal Magnum loads running full charges of 2400. I have had no problems to date.

Standard primers are fine with the powders you are using.

The only time they would be necessary is with slow ball powder like W-296/H-110.

I've ran into problems with Remington small pistol primers. I've also used Wolf, CCI, Winchester, & Winchester small RIFLE primers in the 32mag. I shoot them in a Ruger Single Six baby Vaquero. The Ruger has no problem setting off a small rifle primer. I like CCI the best so far, mainly because they cycle better in my Hornady LNL.
