I know ARs and the M1A should use a harder primer due to the floating firing pin. What about the mini 14? Do they have a floating firing pin too?

[WardenWolf]

While I'm not sure about the Mini 14, it's better practice to always reload in a way that won't have forseeable problems with any gun it could be chambered in. If slamfires are a known issue with certain primers at certain calibers, it is best to avoid using those primers for those calibers.

I know that certain .223 AK's also have free-floating firing pins, so it's not just AR's.

The only primers I know you should stay away from for the Mini 14 are Federal primers. They are too soft for gas operated rifles.

And, yes, the Mini 14 does have a free floating FP.

Back before I knew any better I shot many rounds with Federal primers in my Mini 14 without issue, but not using them is sound advise. I don't use Federals any more for loading .223 that will be shot in my AR or my Mini.

I've fired thousands of .223 rounds through my Mini-14 that I bought new in 1979, which is an early GB Model. All my rounds were loaded with Winchester Small Rifle primers and I never had a problem with them or it.

Hope this helps.

I have used CCI primers almost exclusively in all my reloading with no problems in any caliber.

I have been loading my Ruger Mini-30 with Fed 210M primers for years. I have fired several thousand rounds without a problem.

I contacted Ruger a few years ago and asked them if it was OK to shoot Federal ammunition through my Mini-30. I was told that there was absolutely no reason not to shoot Federal ammo in a Mini. I'm going to go out on a limb here and assume that Federal ammo uses Fed primers. If Ruger claims Federal primers are safe in their rifles, that's good enough for me.

Can anyone here post a link to an actual slam-fire or any other problem associated with Federal Primers in Ruger Mini?

[Uncle Chan]

I use regular CCI small rifle or Wolf Magnum Small Rifle. No problems with either.

[NotSoFast]

I've only used CCI 400 Small Rifle primers and have not had one problem with them.

If you are having slam-fire problems, I would imagine its not a primer problem. I would go to the rifle first. I know the SKS can have that problem if the owner doesnt take his bolt apart and clean the firing pin channel once in awhile... Also I have heard of it happening because the reloader didnt seat his primers correctly.

Use CCI, no problems here.......
