Hi everyone! I am new to reloading and I was wondering if I can use small rifle primers as a substitute for the small pistol primers that .40 needs?
Thanks for any responses

Rifle primers may not ignite reliably in some pistols, as they have a thicker cup. They are also 'hotter' than pistol primers. Substitution would require that you re-do load development with the rifle primers.

Large rifle primers are taller than large pistol primers and will not sit flush in a pistol primer pocket.

Do not use pistol primers for rifle cartridges, other than something like a .22 Hornet.
 
hi and thanks for the posts!
I think I will play it safe and wait until I can find some small pistol primers, this being my first attempt at pistol reloading. :)
I have been told that small rifle primers protrude a bit out of the casing and it seems to me that my glock really smacks the casing when it shoves it into battery. Could there be a premature ignition because of this?
I don't think i'll risk it yet anyway.
thanks for both of your replies

Wake up Boys - He said "small RIFLE" - not magnum pistol.

They will not seat flush - as TJ said - and slam firing could wake everyone up.

Small rifle and pistol primers are the same height, and will seat flush. Ask those of us who've been using them in 9mm and .38 Super for 25 years.
 
could i get some load data on that. interested as i have surplus of cci 400 small rifle primers.

would be for...
9mm frontier TMJ 115-124gr/Hodgdon titegroup, Hodgdon universal. imr PB, 800x.
45acp frontier TMJ 230gr/titegroup, universal. 800x, PB.
40s&w, with probibly frontier...

You don't need to re-invent the wheel. Just take the regular loading data and work from the starting load until you hit your target velocity.

tried it our today, 9mm with CCI #400 sr primers... recipe was...

Titegroup 4.2-4.4 grains/COL 1.125/#400 sr CCI primers/frontier 9mm 115gr.

ran 30 of them though my sig, no problems.
