Home Forums Hunting & Shooting Ask The Gunwriters 7mm Weatherby

Yes, everyone's [bleep] you. Sure. That's it. We're [bleep] you. You figured it out.

I don't happen to own a Weatherby (for good reason) but Quickload does say it could get me an extra 13 ft/s at the same pressure vs my WSM. I think I'll run right out and buy one!!!!!

I just love all the experts that know so much about a rifle cartridge, But don't own one. I have had them all : 7mm wsm, 7mm rem saum, and a 7mm weatherby and please believe me, the 7mm weatherby will way out do the short mags especially with heavy bullets. I would not be afraid of a 1-10 for the 7mm bee. Talking from experience not Quickload.

I'm about 650 ABS and have no troubles shooting 175 in My 7MM Bee and in cold weather also never had a problem even with the Barnes 175 TSX .
When Savage first came out with the Edge which later be came the Axis I bought one in 7mm08 for a beater to carry in the truck the first load i tried was a 140 Grn. B tip it was almost a one hole rifle also shot 145 Grn. Speers great I later found out it was 1:11.5 twist. I don't have a clue what savage was thinking when they made them but I'm glad they did that little salavge has shoot a lot of deer and won me a couple sides of beef as well.

I don't own one or need one.
It is a hard hitting round.
I guess it all depends are you needs, better become a expert at picking brass at the range- those babies 'round here are costly and you won't run them 20 times like you might with a 7x57. The cases are as much a consumable as the bullets and powder. 2 or 3 times might be it.
Maybe, the shop will pitch in a couple of boxes of Weatherby ammo- or maybe they can't find any either.
Just pulling your chain but there is a bit of truth in it.Cheers

I hear you! I'm going to see what the shop will do on the price. I realize that it isn't(much of a)step up from the 7RM, but from the data I've seen I can do 3200ish with a 160 and 3000+ with a 175, and that's good enough for me.

I’ve taken many Axis with this gun & one Elk.

Be glad to divulge my load recipes.

You can easily form 7mmW brass from 7mm RM ... One pass though the Wea. sizing die and you have it.. My WM shoots 160's about 200 fps faster than my 7mm RM!!

Amen. I won’t slam any of the other cartridges but I do know the Bee does what is claimed and mine shoots the 175 Hornady Interlock loaded in Weatherby factory ammo just fine, although I don’t hunt with them. I just salvaged the brass. I give a rodent’s rear what QL says! And the elk roast on Sunday was mighty tasty. Lol 😂 Happy Trails

Case capacity pretty close. 7RM psi is capped by SAAMI, is lower than 7WBY. There have been long discussions why. Running at equal pressure, not that much difference.

Have read as much misunderstanding of basic ballistics on this thread as on any subject that's appeared on this forum in recent years.

1) The 7mm Weatherby case has just about exactly the same powder capacity as the 7mm Remington Magnum, but the longer throat of the Weatherby does allow around 150-200 fps more muzzle velocity at the same pressure.

2) Yes, a 1-10 twist will stabilize some pretty heavy 7mm spitzers, but not all. If you don't get this, then you need to do some remedial research on rifling twist.

3) Once again, most posters are obsessing about muzzle velocity, when what really matters is downrange velocity.

4) Whether any of this matters in the so-called "real world" (sometimes I wonder if that exists on the Campfire) is another question,

Yes, and I'm sure that you know that the Wby freebore is definitely part of the discussion.

edit: sorry, M D was just a little quicker typing than I.

The 7 Weatherby is about neck and neck with the 7 Mashburn, correct?

John, Aren't Weatherby guys speeds demons in the first place? Wanna be race car drivers, maybe. My view is -What are the numbers are like out of a shorter barrel?
A 22" barrel takes many out of the race.
Oh yeah, 24 CF hovers in and out of reality and I could be part of the problem . Cheers

Yep

JB was pretty quick.

My smith thought the 7RM was potentially more accurate than the Wby. Now, that should open a can of worms.

In fairness to the Wby, if it’s carefully chambered with a tight freebore, accuracy can be excellent.

I went with the smith’s suggestion; he’s sort of an accuracy nut. I have no regrets.

DF

Yup, that’s about what the Mashburn does for me, 3250 with 160’s and 3050-3100 with 175’s depending on the reamer and barrel length.

beretz,

And of course you're using pressure-tested loads in the 7mm Mashburn....

Of course, all the folks on the 24CF only work up pressure tested loads checked to SAAMI velocity specs on a calibrated chronograph.

What reality is anyone in who would shorten any of the 7mm magnums to a 22” barrel? Get a grip....buy a 7-08 if you need a 22” barrel! LOL!

I'm going a full 26", though I realize that is sacrilege to many of the Campfire denizens.
