PRIMERS . Small vs Magnum vs Sm Rifle in Pistol

[gle3105]

Great video by Mike Stoker of Super Vel ammo answering age old questions.
Myself I’ve ran the same test (except transducer psi ) and found the same.
Varied 1911 mainsprings trying to find a fail to fire. Went very low and still fired. To slow to use.

I believe that the milspec primers (cci #41) are the primers that will ftf from a light strike. I think theyre designed to have a larger internal space so they dont fire from a rebound strike in some situations, iirc

Talking about using in a pistol. Not a rifle.
I use 41’s frequently

Harder cup

Ok. Im just saying ive been told that someone used them in pistols and got some ftfs.

MM,
You heard right. Using a 41 especially in a pistol can definitely have a FTF ( handgun jargon ) fail to fire. Harder cup.
AR’s have a floating fire pin.Once you release the bcg from a held back or in regular firing on a round it will leave a small firing pin mark on the primer.
No place for a thin skinned primer cup. Like using a regular pistol primer .
Mike in the video does in fact mention the primer cup hardness of small rifle primers and that some lighter tuned pistols might not strike hard enough.
Stock 45 1911 springs on most are 23 lbs. I tried as low as 16 lbs (not a norm ). At 19lbs I still had 100% with small rifle primers. After that sporadic and hammer fall became expectedly lethargic.Didn’t try 41’s in my trials. So no need.
Just a neat video by a ammunition manufacturer
Appreciate you taking time to read my post and your replies.

I put an extra power firing pin spring in my Springfield XD 9, so that I can use other primers if necessary.

When small pistol primers became non-existent last year, I reloaded for my XDS 9mm using Remington 6 1/2 primers. Worked great with no FTF's at all.

Biggest and main concern was PSI. For most.
Probably will be a lot more reloads with other than listed primers being loaded. With the scarcity of.
