Thanks for the suggestions, everyone. I do handload, and I've tried the following primers:

CCI 500
CCI 550
CCI 400
Remington Small Rifle (don't immediately recall if they were 6-1/2 or 7-1/2)

Mild loads or near-max loads, 38 special or 357 magnum, all produce the same hiccups with primer flow in my particular rifle. Though, sometimes it's better or worse, depending on the load. Since my 44 magnum barrel works so well, I figured I'd just rechamber to something that uses large pistol primers, since they work well in my particular rifle. Also, since I'm using this on an SB1 shotgun frame, my rechamber options are somewhat limited. If I found a small primer that didn't flow so bad, I'd just keep the 357 magnum chambering and be happy.

I'll verify which Remington small primer I've tried, and if it wasn't the 7-1/2, I'll give those a try.

Has anyone used the CCI 41 military small rifle primers in their 357 Handi? I recall reading somewhere that these have the most robust cups.

Remington 7 1/2 primers are Bench Rest rifle primers.

The CCI Small Rifle Military Primers #41, are supposed to be the hardest or as you state "the most robust".
I can't say I tried them yet in my rifles, as my LGS doesn't stock them.

Yes, agreed, Bench Rest primers in the small rifle form factor. Same size as the Remingotn 6-1/2, no?

From the Calhoon link:
Quote:
small pistol primers are .017" thick and large pistol primers are .020" thick.
None of those you tried have .025" thick cups, use either the CCI450 or BR4 or Rem 7, all LR primers have .027" cups. CCI41 primers have a bigger gap between the tip of the anvil and the bottom of the cup than other CCI SR primers and a .025" thick cup. I'd expect no fires unless using a Wolff EP hammer spring and even then may be a problem.

The cups of the Remington 7 1/2 primers may be as thick as the CCI 450 or BR4's however they are a much softer material. I pierce them with regularity in my 17-204 while the BR4's or 450's look perfect. Larry

A gun is just like a parachute, if you ever really need one, nothing else will do.

Thanks for the recommendation. I'll give the BR4's a try.
