Tell me about your 7mm Weatherby magnum.

Yoteklr · Apr 17, 2023

I've had two 7mm Remington magnums, and have a 28 nosler, and 7mm wsm currently.
My 28 Nosler is pushing 175gr Bergers at 3190.
My 7wsm is shooting 150gr fast! ( I don't want to say how fast).

my past 7mm Rems accuracy loads with 162 to 168gr was always right at 3000 fps. They could go faster but not with consistent accuracy.

I got a few hundred Norma 270 weatherby cases cheap when Bullets.com went out of business and a several hundred 162 Amax all of which is burning a hole on my shelves.

I'd like to know what loads barrel length and velocity ( with accuracy) you guys are seeing from your 7mm Bee?
Thanks.

There was a guy on LRH looking for 270 WbyMag cases, should you want to sell.
7mm Wby cases are not difficult to find. As I detest the idea of reloading one round in another so close in size, if it were me I'd swap them.
Then again, I probably have, um, too many 7mm Wby cases.

The slow load is 150 TTSX at 3050fps. I could push it faster, but Dad has killed plenty with this so there's no need to.

Hammer Hunter 131 at 3550fps. Great load, but the 131 jams in a Weatherby MkV action. It has to do with the straight profile of the bullet and the lip of the barrel.

Hammer Hunter 146 at 3225fps. I pushed for a year to get Hammer to develop the 146 for the Mark V action, given my problems with the 131. Weatherby gets 3275fps in their loaded ammo, same bullet.

Thanks, what is your loads and barrel length for those? Sounds like the 7 wby could best 7mm RM by a good margin with the same pressures even though they're about the same capacity.

I should have mentioned, there's no danger of mixing brass because I dont have a 270wby right now.

26 inch factory barrels for all of these.
I have a 24 inch custom which has shot 160AB factory loads at 3020fps. However, they no longer make those loads so my couple of boxes are hoarded for that rifle.
