Older Weatherby

[jdyoung]

Tell the shop owner you are interested and would like to confirm the caliber. I'm sure he would as well. Suggest he cast the chamber.

My 1963 German action Mark V is also marked .300 Magnum.
It is definitely a .300 Weatherby. Most likely that gun you are looking at is also.
Just checking Gresham's excellent book on Weatherby shows 300H&H was chambered in 1958-59 in the Mark V built in South Gate Serial numbers from 15000-16224 but not on the German actions.
I don't see other 300's listed on early ones.
Maybe give Weatherby a call and double check.
Good luck with it, I love mine!

If you like the rifle and the price is right, buy it.
Then figure out what it is chambered for.
And hope it shoots good.

It's most likely .300 Wby, but don't guess. Weatherby could tell you from the serial number. Some of those old guns are real shooters. Might have a 1:12 barrel though.

If it won't chamber a .300 Weatherby or .300 H&H it COULD be a .300 Win or .300 Norma
My GUESS is it's .300 H&H or .300 Wby

My guess is....Call the gun shop!

I know that the pre 64 Model 70's stamped
.300 Magnum were .300 H&H Magnum as it was the only .300 Magnum produced at the time.....

It is a Weatherby...not model 70 and the .300 Weatherby was produced in 1944

There is a local gun shop near me, it has an older Mark V and the barrel is only stamped 300 magnum. I like the gun and I don't know if that 300 wby mag or 300 win mag.

Ask the gun shop to put a 300 Weatherby shell in it... problem solved...and NOT A 300 WM.... Because it will chamber! And leave A TON OF HEADSPACE and other space!

I saw a guy at a hunter's sight in program shoot 300 Win Mag cartridges in a 300 Wby chamber. It hit the paper at 100 yards but not very accurately. When he ejected the spent brass it looked like a 300 Wby with a neck about an 1/8" long.............sent him on his way to go buy the correct ammo.

 

[bocajnala]

That's one way to fireform....

 

[Tulsa Reiner]

I guess there is another option too

But you said it is a (Weatherby) Mark V, and he answered for Winchester Model 70. I doubt that Weatherby ever made rifles in a Model 70 action. Does anybody know differently?
It sounds like you already have the answer, before I posted this.

 

[Rflshootr]

Tulsa I think he meant the other option was a 300 H&H mag

 

[Scammie77]

I would call weatherby with the serial number and get it straight from them. Everytime I have called weatherby they have been very helpful.

 

[Dmagna]

Thanks for the input. I am going to pass on the rifle, didn't really want a 300 wby and it's a little bit too much money for the rifle.

Weatherby has a service that I have used in the past . Send them the serial number of the rifle and they will send you a written letter as to the date of Mfg. ; the caliber, and the first gun shop the rifle was shipped to. It cost $20.00 about 15 years ago. Split the cost with the gun shop. For $10 bucks you eliminate any guessing .
