Lee-Enfield

[hybridatsun350]

The STANDARD for proofing is 200% of a "normal" charge. Lee-Enfields were designed for the high pressure 280 Ross cartridge but time was short before WW1 so, they were made in the well established 303 round. In the De Haas Bolt action rifles of the world, He refers to the Lee Enfield as one of the strongest actions in the world. No one thinks anything about rebarreling a M98 8mm Mauser (35,000 PSI) to belted magnums rated at 65,000 PSI. Not to mention, the original 8X57 was only loaded to 35,000 and modern factory loads are normally rated at 57,000. When was the last failure that you heard of with a M98?

You telling me something is true wasn't my idea of evidence or proof. A 7.62x51 proof load is 67,000 psi. How is that 200%?

Also, the strength of the Mauser action is of no consequence to the strength of the Enfield action.

Edit: I'm pretty sure the .280 Ross was a high-40k psi cartridge (Just like the .303). What was your point there?

200% of the original 303 load (49,000 Lb) would be the standard for proofing, and when reproofed for the 7.62 conversions it would have been to 2 X 60,000. I was only using your logic with the comparison to the M98 Mauser.

We're not talking .303 here; we're talking 7.62x51 and NATO's spec for a 7.62x51 proof load is 67,500 psi.

What logic are you referring to? My Schmidt-Rubin analogy?

LOL!

You lucky lucky bugger !!!

I want !!!

I was referring to your idea that the Lee Enfield was not strong enough because the original cartridge it was built for had a low pressure rating.......The Proof load for a 7.62 is 2 X 67,500. The normal pressure developed is 67,500 or less. In the old days......Ammo would vary greatly, particularly surplus ammo. I remember people talking about ammo designed for machine guns being heavy overload when being shot in handguns or rifles. there were some case failures but I never knew of a catastrophic failure caused by the heavier loads. And by the way......SAAMI says that it is safe to shoot 308 in 7.62 rifles and visa versa even though there are minor differences. The other "Elephant in the room" Is how gases are handled if there is a failure. M98's have ports in the bolt that direct them down into the magazine, away from the shooter's face. Other rifles are not so well designed, ( I don't remember how the Lee Enfield deals with it and I am too lazy to dig out mine to see) So, even though the action is strong enough, the emergency gas handling system might be insufficient in the instance of a ruptured case to protect the shooter from hot exhaust. Case failures are much more common than any sort of action failure.

You're telling me a proof load for 7.62x51 is 135,000 psi!?!

The Enfield has a port on the left side and a cutout on the right for gases to escape in instances of case failure. Once again, I'm done discussing this.

PROOF LOADS ARE 2X NORMAL LOAD PRESSURES............

PROOF LOADS ARE 2X NORMAL LOAD PRESSURES............

NEWS FLASH! THAT IS INCORRECT!

Look up the London Proof House, It has been in business since nearly the beginning of firearms......and is the standard that most other Proof houses go by.......So, What is a Hybrid Datsun? A Kia?

The 7.62mm #4 Lee Enfield is re-prooved to 22 tons - whatever that is in PSI equivilant.

22 long tons is approximately 49,000 psi.
