Home Forums Hunting & Shooting Hunting Rifles BETTER THAN A WEATHERBY FOR XMAS?

I'm not getting your question, math

They changed the twist rate on the 7mm Weatherby did they not? That might be the problem. I love weatherby's but some of the things they do make me shake my head.

I don't know elk, but I ran the gambit from 140 to 160 gr...

I haven't had a new Weatherby in quite a while, so maybe I've missed a transition to free floating. But when I was a buyer they had a pressure point bedding system, even my original Fibermark with the McMillan stock. Campfire slang is a speedbump.

I never had a problem with my MkV rifles, but I have tightened up groups for pressure point bedded rifles of other makes that had an iffy fit between barrel and stock at that spot. A few wraps of tape took out the shot-to-shot inconsistency in pressure being applied.

1:8.5

Maybe so, but it's their guarantee of sub MOA I'm holding them to. I've probably owned two dozen Weatherbys in my life and this is a first. Very disappointing.

They need to hold up their end. I'm just thinking diagnostics out loud.

I'm pretty steamed

I have owned 3 7mm Bees and every last one has been a shooter. Something is not right, send it back.

It's one of the first batch of 500 rifles out of Wyoming. Hope they didn't goon something up!

Anything is possible it is man made.

They need to shitcan that big diagnostic range fee BS posthaste. Weatherby markets the MkV as a premium product and I don't see their desired clientele putting up with that kind of stuff.

Because we let it happen. It used to be, every Weatherby rifle came with a target. They dropped that a few years ago, but then again I gather there were not many issues with accuracy. So now they have this new horseshit called "Range Certified" which provides a target (that costs an extra 500 bucks) to what they used to give you for free. as as you say, it is a premium product.

Jorge,

a 1:8.5” likely will do better with a heavier/longer bullet based on a lot of testing I did with 7 WSM loads for long range match shooting. Try a 168 - 180 grain bullet first before making a final decision. I used a 1:9” in 7 WSM’s, which produced best accuracy with 175 - 180’s in lead match bullets and mediocre groups with full power loads with bullets lighter than 160 in conventional cup and core bullets.

In Barnes, the 150 TTSX is longer, which is the factor which really is related to twist rate, and yet light to keep recoil down while providing high velocities Weatherby shooters like.

I also encountered bullets spinning out of jackets above 3200 fps in faster twist barrels. So perhaps try starting at lower velocity with the Partitions. A bonded bullet like an Accubond might better handle the higher velocity and twist rate if you like them. I ran a few tests runs with the 160 Accubond at a 1,000 just for the sake of trying them, and they could produce 2 MOA 10 shots groups at 1,000, which is not too bad for a “hunting” bullet.

The 7 Weatherby has enough more than enough muscle to push the heavy bullets at optimal velocities.

With the Sub-MOA guarantee, the range fee is absurd and likely a breach of their warranty.

Good luck, sorry for the frustrating new rifle. Hope it sorts out soon.

jeff: I also tried the 175gr Hornady, not a particularly long bullet, but I figured the Partition (160) would work, but all of them shot patterns. I have no idea what the issue could be. Action torque setting were to specs (55in/lb) no apparent barrel to stock contact and proven loads in other 7 Weatherbys as well as two different scopes.

The older barrels were 1:9, then again Weatherby should state that up front. I sent the rifle back already. Once it gets back, I will try the 150 TTXs I suppose. this is what they currently market:

Bullet Type Ballistic Coefficient @ Muzzle 100 Yards 200 Yards 300 Yards 400 Yards 500 Yards
120 Grain TTSX 0.373 3430 3148 2884 2635 2399 2176
140 Grain TTSX 0.412 3250 3007 2776 2557 2349 2150
150 Grain Ballistic Tip 0.493 3300 3093 2896 2708 2527 2353
154 Grain Spire Point 0.433 3260 3028 2807 2597 2397 2206
160 Grain Partition 0.475 3200 2991 2791 2600 2417 2241
175 Grain Spire Point 0.462 3070 2861 2662 2471 2288 2113

1:8.5" twist shouldn't cause this kind of problem.

Well, here is their guarantee:


GUARANTEED SUB-MOA ACCURACY
All Mark V® rifles are guaranteed to shoot a 3-shot group of .99” or less at 100 yards (SUB-MOA) from a cold barrel when used with Weatherby® factory or premium ammunition.

https://weatherby.com/rifles/mark-v/

It should run with their ammo and they should honor their warranty.

No sir. My 1-8 Mashburn shoots everything from 120 to 195 pretty well. I’d bet the guns just sick.

Weren’t the older 7 Wbys a 1-10?

It will make for some lively discussion at the Dallas convention this week. I'll have two, big shot Dallas attorneys with me that also happen to be Weatherby owners....
