Ammo and other questions??

I dont know if this belongs here but I thought I'd give it a shot.(parden the pun)
What are the differences between steel cased Brown bear and Nato 308 as far as primers go? Is one harder than the other?
I was shooting Brown Bear 308 in my enfield 2a because the South African Nato would get stuck in the chamber and not extract.
The reason why I ask is after shooting the Brown Bear through the rifle, My son wanted to fire some of the German Nato plastic practice rounds (no recoil) So I loaded the rifle with them and they did not fire. I also noticed this with some of the Brown Bear rounds needing to fire them twice to get them to discharge.
I thought maybe the Brown Bear wore the firing pin down, or could it be something else? I recently Took the bolt and bolt head/extracter out and cleaned it.
Something must be causing the firing pin not to strike the primer(s) like it should.
Thanks in advance,
Craig

I doubt it's an ammunition issue. Try reposting in the Gunsmithing section with a description of the firearm, etc.

I also have an Ishie in 7.62x51(not 308) like yours

Not to get into the whole 308 vs 7.62 issue..I have fired academy 308 in mine, but quit...the CUP for 308 is higher..why risk an awesome 60 year old weapon?

I'd buy a new firing pin spring and check the firing pin as well..they are reeel pointy

get these from e gunparts if nowhere else

Surplus Nato sticking is another issue..never had that problem..I'm assuming that your chamber is spotless.no dried cosmoline in either it or the inside of the bolt body or bolt head?

while you are ordering parts, order a spare extractor spring and extractor as well.Extractor is unique and not same as 303.if it hasnt broken yet, I garanteee it will :cry_small

Let us know

The Nato that was sticking was South African. I cleaned the heck out of it. I hope I didn't hurt her by using steel cased ammo. The firing pin is pretty dull and flat instead of pointy. So I'm assuming the steel cased has harder primers?
How do I move this thread to Gunsmithing?

PM Mikey, He can move it for you. Or just start another one.
