Is my son's used Wxby rifle a 300 Winmag or 300 Wxby Mag?

[10gaugemag]

Saw this at the range once. A guy shooting a .300 Weatherby couldn't figure out why his groups were so bad until the rangemaster showed him a piece of brass that came out of his gun. He was shooting .300 Win Mag ammo in his .300 Weatherby Mag rifle. The guy said he just went to the gun shop and asked for "a box of .300 magnum" and the guy behind the counter just sold him a box of .300 Win Mag.

This is like the kid at the gunshop telling the owner that he had missed a buck because the owner hadn't boresighted his rifle correctly the day before. Some people really don't need to own guns.

GUYS SERIOUSLY.... STOP!!!

If it will chamber a .300 Weatherby that is what it is!! PERIOD end of story. It's that simple.

If it's a .300 Win mag it WILL NOT chamber a .300 Weatherby round, .300 H&H will NOT chamber a .300 Weatherby..

Or it could be a .340 Weatherby, yes?

With a .30 cal barrel?

Look just funning with H&H. Do you know the barrel is .30?

For those that are confused and don't have a clue here is a picture that shows the physical differences between the WBY and WIN.


These are a the .30 cal magnums I have next to a 50 BMG for comparison.

The rounds in question are.....

1) 300 Weatherby Mag. is the fourth cartridge from the left.

2) 300 H&H Mag is the fifth cartridge from the left.

3) 300 Winchester Mag. is the sixth cartridge from the left.



As you can see both the H&H and Win Mag will fit in a WBY chamber, where the WBY will not fit in the H&H and Win chamber.

The WBY is nothing more than a "improved " version of the 300 H&H. When fired in the WBY chamber the H&H's body taper and shoulder are blown out thus increasing powder capacity.

I have made hundreds of 300 WBY and 7mm STW cases from the ol 300 H&H by just fire forming them. The 300 H&H derived from the bigger 375, the father of all .532" belted magnums

I was refering to the Mauser 98 era Weatherby rifles, the ones with the two forward lugs and the one rear lug. They were made in the 50s, long before the Mark V rifles.....chris3

Well Jim.....

As long as we are playing the magnum and non magnum length, belted case based on the original .375H&H game with no regards to bore size, It could also be a;


.375H&H
.264WM
8 Rem Mag
.416 Rem Mag
.458 WM
7 Rem Mag
.358 STA
.458 lott
7 STW
.338 WM
.358 Norma
.308 Norma
.270 Wthby
7 MM Wthby
.358 Norma
.358 STA
.375 Wthby
.257 Wthby

Just to name a few. However if it's a German built Mark V and it's marked .300 Mag and it will chamber a .300 Weatherby round there is no freaking way it's a .300 Win Mag or a .300 H&H so that kind of narrows it down a bit. Sticking a .300Win Mag in it and seeing if it fire forms to length and shoulder dimensions of a .300 Weatherby ain't the brightest thing I've ever read on the net, especially when there is such simple solution at hand.

A drop of wax on the shoulder of a chambered cartridge would tell you pretty quickly without damaging anything.

 

[Art Eatman]

Aw, now, H&H, give it at least a 40-watt if not 60.

MErl's probably given the most useful answer.

 

[rcmodel]

I think it has been re-barreled to .30 Eargasplitten LoudnBoomer.

And re-blued to match the Weatherby finish so you can't tell.

H&H missed the .244 H&H magnum. Given his screen name, I find that inexcusable.

 

[gamestalker]

I just have to get in on this one. I'm 100% with H&H, unless it's a 300 WM with nearly a 1/4" (.225") of excess head space at the shoulder, a 300 Weatherby cartridge isn't going to chamber in a 300 WM, no way, no how, not even if you tried to beat the bolt closed with a hammer. So if a 300 Weatherby will chamber, it's absolutely and positively chambered for such.
