300 weatherby

[4xforfun]

Doesn't WBY now make a smaller 6.5 than the 6.5/300 WBY? 6.5 PRC/6.5 RSAUM/6.5-284 sized round?

That would be the ticket for recoil/round count/energy/speed/range balance.

Just my .02

A 300 Wby will take down anything in North America. I love mine and is easy on recoil with a Weatherby Accubrake. Shoots .75 moa at 200yds. That being said I built a 6.5 PRC it is a lot lighter and is a lot more fun to shoot and uses 2/3 as much powder

I did the same, love my 300 WBY, but shoot it a lot less since getting my 6.5 PRC last February.

My go to load for the 6.5 PRC is 156gr Berger over H1000 with an average MV of 2887 ft/sec. They shoot less than 3/4 inch at 200yds. At 600 yds. they have a velocity of 2124 and 1563 ft-lbs compared to Hornady factory 300 wby mag 180gr Outfitters at 1986 ft/sec and 1577 ft-lbs ( Weatherby ammo is a lot hotter) but just to show the 6.5 PRC can hold its own at range.

Wow, that is good performance on a "light grain for that size game load". Go hammers.
Thoughts for 5.56 hammers that will outperform 77 SMK's?

What barrel twist?

I'm a Weatherby nut and have them all from the 240 to the 338-378. Most are on the second or third barrel. If you're wanting to shoot it without a brake, you can't beat the 257 with the 92 grain Hammer Hunter. With H1000 or H4831SC you'll near 3700fps and it'll be a laser beam to 400yds and will be a pleasure to shoot. There are many other opinions above the 257 and I would recommend (if you want to see impacts), have the barrel threaded to use a brake. I would also have the rifle you have posted to be be pillar bedded and consider an after market trigger. For a minimal cost, it's more than worth it if you are wanting exceptional accuracy.

How many grains of powder do you put in that 257 load?

H1000 92gr Hammer Hunter 78.5 running at 3610 is the flat node for this rifle and easy on brass. 4831SC was nearly the same and RL22 velocity was just over 3700 but was dirty and had velocity change from 40 to 85 degrees was a 50fps+ velocity change.

And get a faster twist

I have a 1-9 and a 26 "

I'm a 257 man…but for a big game option a 270 weatherby does carry some mail..somewhat efficient and twisted right some of the new heavies can be pushed pretty fast…

I happen to own three MarK V rifles. The Mark V deluxe in 270 Weatherby Mag and the Mark V Deluxe in 300 Weatherby mag. Both of these are Japanese Rifles from the Late 70"s The Mark V Ultralight ( 6 Lug ) is chambered in 270 Win. Speaking just for myself, The .270 Weatherby mag shot extremely well at the Bang Steel shooting school where I was able to shoot and HIT targets at 1000 and 1100yards over and over using the Nosler 150 Grn Accubond LR bullets at 3000 fps. This year I will return with that rifle to the school and then go directly on a White tail deer hunt , in N. Carolina where a set up on a large Bead Field will allow me the opportunity for a 500 yard shot . This year I will be using the Nosler 130 Grn Ballistic tips, at 3300 fps . Love the rifle and Im a huge fan of the .270 Bullets on Whitetail Deer and Mule Deer, and medium sized game in General. Both of the Mark V Deluxe rifles still have their factory Original 26 inch barrels. Below are two targets one is three shots of the 270 ,130 Grn Bullets at 300 Yards about a month ago, the other is 5 shots of the 270 ,150 Grn. ABLR bullets at 100 yards. Respectable hunting accuracy for a 44 year old rifle. Scope is a Leupold VX3 8.5X to 25 X Wind plex on Steel Dual Dove Tail Rings and Bases. No Rail required. When the time comes for new barrel, it will go back to Weatherby . Same 270 Weatherby mag caliber, no question.

What barrel twist?

1 IN 8

 

[Lenny Foffa]

10 twist so the ultra light in 270 win and the 270 Weatherby mag probably won't shoot the new 170 Grn VLD bullets!I have not even tested them !!! These are both deer rifles ,when the game becomes Elk,or some other big animal,then the 300 Weatherby mag comes out of the safe!!

There's a 6.5 RPM falls in the 6.5 prc range. I love Weatherby but I don't know if this college is going to last.

I think the 52g Hammer Hunter would be my choice. You could run up to the 70g Hammer Hunter.
