yes,I just tried one in a unloaded case.it fit,but when I fired the unloaded case the primer backed out a few thousands. don't know why it did that .so I thought I would ask if that's not a good thing.any advice would help.I had a similar problem when I was gifted some incorrect primers (that Cabelas can't return). Except of the magnum variety. From what I have gathered, it may necessitate a change in your load to keep pressures correct as a 'stronger' ignition will change your primer/powder reaction and speed.
I am gathering primers as they are available locally to make sure to keep on hand in the event of another large scale shortage, but the answer would be good to know for certain in the event you needed to make a bunch with what you have on hand (if you are a SHTF believer... but then again, you'd probably have a few thousand squirreled away )
The primer in all cartridges will back out when fired. You don't notice it because when the cartridge fires with powder in the case the pressure slams the case back into the bolt face forcing the primer back into the pocket. What you saw is perfectly normal.thanks but I'm still concerned about the backed out primer issue.any one know what the issues there might be
Welcome to the forum. I'm glad we could help.thank you all so much.I'm going to use all the advice here and work my load back up and start using the Srp that are easier to find.again thanks to all who gave their knowledge.
How would it cause a jam? The primer can't unlock the chamber. I've been doing this for years.The small rifle primer produces a longer stream of ignition in the case. This will allow the primer stream to push the bullet forward before the propellant explodes.
The primer flame or stream moves forward to the base of the bullet before igniting the propellant. This can cause the pistol to jam.
Simply ridiculous and doesn't help the OP at all, physics or no physics.The primer flame or stream moves forward to the base of the bullet before igniting the propellant. This can cause the pistol to jam.
Firearm manufactures make it pretty clear they don't think you should reload in the first place.In general it's never a good idea to experiment with high pressure explosions without proper training or testing and taking the advice from a bunch of unknowns on the Internet isn't very dependable. I prefer to follow the recommendations of the people that actually designed, tested, and built the weapons and the ammo, they seem to have the advantage over me or anyone else that is a common hobbyist. Contact the pistol manufacturer and ask them if their pistol would work reliably and safely with the rifle primers (my guess is that they wont recommend it).
On the common sense side (I know, there isn't any such thing as common sense nowadays but I'm an optimist) it would seem to me that it would take a different primer mix amount to ignite the powder volume in a rifle cartridge than it takes to ignite the powder volume in a far smaller pistol cartridge and that leads me to believe that the rifle primer will have more priming mix which means more pressure. Probably not lots more pressure but considering the small .380 case I'd say that the relative increase in primer mix is pretty large, maybe large enough to cause issues.
Then there's the difference in primer cup thickness; according to one expert (German Salazar) the thicknesses are
Small pistol .0173 - .0178"
Small rifle .0205 - .0210" - Commercial
So I'd want to test the ability of the pistol's firing system to ignite the thicker rifle primers reliably and if this is a carry gun that I'd want to rely on for self defense then I'd be very thorough in my testing.
Personally I'd check with the manufacturer and if they said it's safe then I'd experiment and see if it's a reliable combination knowing that there are slight difference in every pistol and what might work well for one wont necessarily work well in another.
Exactly what I was thinking. I can't remember ever seeing a firearm manual that didn't say the bit of reloads are bad and will void the warranty.Firearm manufactures make it pretty clear they don't think you should reload in the first place.
