Weatherby Mark V question

FWIW,
I never fail to dry out the chamber as well as the bore, before shooting. Simply drying the bore with patches does not touch the chamber. That is, what fits the bore tightly is too small.
 
That’s for the first or second firing. After that they headspace on the radius shoulder.
The belt origination was on the 300 H&H which really needed it as there is barely a shoulder.
No longer hunt but when I did Weatherby was always my first choice. The first shot through a clean cold barrel was always on the mark. Nine locking lugs, radius shoulder, insane freebore, I’ve no clue why that skinny barrel did so well. And my 257 was my favorite. Is there a flatter shooting cartridge today?
Ahhh. My 257WBY lighting 75 gr bullets on fire!!
 
These are my Daughter’s favorite hunting rifles, she’s bought and sold a few. Her current one is absolutely beautiful rifle chambered 300 Weatherby Mag.
I don’t recall her ever applying extra oil on the bolts during hunting season.
She’s never complained about the recoil and the deer never run away.

Jim

Bro, she runs a pawn shop, her ranch, three kids while helping her husband run a tow company.

Not much time for more men.
Well…you raised her right and luckily it took. Good for you! I had two boys. I couldn’t imagine raising a daughter when the boys start sniffing around. I’d be cleaning my shotgun on the front porch.
The first good rifle I bought was a German Mark V in 300 Weatherby. It’s a great gun and the recoil didn’t bother me a bit. The Weatherby ammo recoil felt like a shove. My reloads felt like a punch. I never did figure out the secret Weatherby load.

I’ve never had the desire for a 300WM, never understood why anyone needs the Weatherby version. I do have a Mark V Ultralight Weight, but it’s a 30-06. Great mountain hunting rifle, and plenty of cartridge for anything that I hunt. I agree with a good cleaning, and light oiling. Then foul the barrel before hitting the woods.
The Wby version was the only game in town in the early post WWII days and the 50s. You had the 300 H&H for competition. WBY advertised heavily and sometime had exaggerated claims. It had a good action, good barrel and was a 1 1/2 moa with good handloads. Wby supplied great reloading data and brass from Norma which loaded the factory ammo which could also be obtained with factory Nosler partition bullets.
Now, there is no reason for it with all the other 300mag rounds. But for a do everything .30 cal you will have a hard time beating a 200 gr at 3000fps.
 
I have a number of Weatherbys. Don’t hunt anymore but I did extensively years ago. Especially when I lived in Montana. I don’t recall exaggeration in any Weatherby ads. In fact compared to today they were right on target. ( no pun).
The only hunting rifles I’ve owned that a cold clean barrel made no difference at all. The only thing that probably could have been eliminated was the belt, but in that time it was fashionable. Always wondered about the radius.shoulder. Not a problem but just strange. Now shooting antelope off the hood of my truck, before range finders were common, 257 is hard to beat. Pacing off the distance is not that accurate but my best was 585 of my paces.
I find them to be fabulous hunting rifles. High in price and noise, but well worth it.
Is there a flatter shooting cartridge?
 
I’m helping a friend out to clean and prep his father’s Weatherby Mark V 300 magnum for hunting season. I’m sure the rifle has been fired very few times, but I have no idea of its condition until I see it on Sunday.
Is there anything special I should be looking for on this rifle to make sure it is good to go? I’ve never worked on a Mark V and just wanted to ask if there are any special things I should be looking for or points to check.

Clean the barrel with a good carbon solvent. High powder burners will build up carbon quickly and impact accuracy. Finish off with a light lub, sight it in and go hunt. Good luck.

Well, kind of. If I remember correctly, they claimed 1" groups at 100 yards in the late 1970s. At that time I was working at the post office in CA. One of my fellow workers, a Korean War Veteran had worked with Weatherby in Southgate, CA. I don't remember his exact title but he was one of the workers that test-fired the rifles before they were shipped out. He said that if the rifles shot anywhere near 1" they were good to go out the door. He was a good friend. He had a heart attack and passed away while deer hunting. They found him 2 days later still holding onto his WBY. He always claimed that particular rifle had shot under 1" and he had bought it on lay-away.

I remember an ad in the late 40's claiming 3400fps with a 180gr using the old Mauser action rifle. No barrel length given

It must have been quite an experience to know him personally. I knew Fred Hunnington and he used to send me hand written loading notes on the .280 Rem.. They were hot and would expand primer pockets in the Rem. brass.
 
I have owned and hunted with a 240, 257, 270, 7mm and 300 Wby. They need no extra steps to prepare than any other action. If you are hunting in extreme cold consider a dry lube.

I don't recommend ever firing a cartridge in a chamber it's not designed for. It could be catastrophic at worst and problematic at best. Happy hunting!

Many of the early .300Wby cases were fire formed from .300 H&H. It was quite commom without any problems.

Well, the bolt was a mess with tons of gunk inside it, and the barrel is in really bad shape. Currently, I have it soaking in Free All. Do you think I can clean this barrel up to make a good hunting rifle shooter out of it 1.25-2.0 MOA? I’m planning to hit with JB paste tomorrow night.

Steel wool and JB wrapped around the jag. Set the barrel up so you have something to stop you from exiting the bore with the jag. About fifty strokes should all you need. By the way, I have fired 300 Win Mag through a 300 Wby. I didn't chronograph it. I should have. WH

I did almost exactly this on a barrel much worse.
Just shot it again last week. 3/4 MOA at 200. Then my son killed a mule deer buck with it.
So gad I didn't toss it.
