What would happen if someone were to load and the the round did chamber - a 416 Rem swift A-frame in a 375 H&H?

The gun was a old Bruno 602.

This did happen but the person was notified of wrong cartridge in time. Removing the round was difficult. But it was clearly chambered.

If he had pulled the trigger what would have happened? I know the outcome is not something one wants - shooting a wrong calibre cartridge. But what would be the outcome especially in a large calibre rifle.

The person was not me. I did the notifying.

Thanks,

Mike

I'm afraid you'd need MARS if they had pulled the trigger pretty quickly. Glad you caught it in time. It probably would have destroyed the rifle and severely damaged the shooter.

I guess that .375 had a very long and wide freebore. If that was the case, I would expect the barrel to rupture dramatically at the point where the bullet hit the rifling.

The stock would probably have cracked as well.

A friend of mine chambered and fired a .375JDJ round in his Browning A-Bolt .300 Win. Mag. It was a dramatic failure of metal and wood, but he only got a couple of cuts and abrasions. He was scared shitless, however.

How is that even possible? I could sure see it the other way around though.

It did happen.

Slammed a 416 round into a 375H&H Bruno 602. Bolt closed. Was following up on a wounded buffalo.

When the round was extracted - the bolt was really stuck. Had to place the butt plate on ground with the barrel pointed upwards and the bolt handle had to be slammed to open. The round extracted.

Glad the rifle was not fired. An exploding rifle would have been very painful.

How about the opposite?

On leaving for a Canadian Moose hunt in 2005, my partner grabbed two boxes of ammo for his 416Rem, but one of the two was 375H&H. While hunting he fired a couple rounds and was surprised when the bullets didn't go where they should have. Close examination led to the mistaken ammo issue.

I had fun telling him about that .375 bullet rattling down the .416 bore of his rifle. Fortunately his error caused no damage to the rifle (or the Moose )

I take it that whoever did this thing didn't bother to function test/fit all his/her rounds through the rifle just prior to the hunt and/or didn't bother to check his/her pockets for wrong ammo prior to the hunt.

If someone is unfamiliar with a rifle or ammo the correct ammo/rifle combination should be clearly marked with an indelible marking pen.

Sounds like a whole lot of somebodies had their heads squarely up their nether regions for something like that to happen...the hunter, the PH/guide and any support personnel that handled the ammo/rifles.

Not to put too fine a point on it or diss/flame the survivors.

Bad things. Nothing good.

Seen the remains of a Musgrave Mk4 where something similar happened.

Guy ordered one in .308W, and got one in .270W. Gunshop didn't check, and neither did he.

He brought it back complaining that there was something wrong with it, since on the SECOND shot it blew the magazine floorplate out, bolt was locked shut and stock was splintered round the magazine.

Action was a Spanish Santa Barbara Mauser (similar to the Parker Hale Saeed blew up a few months ago).

Shooter was uninjured, but understandably somewhat gunshy.

I blame the gunshop, since the customer was a total n00b.
