As i've posted already, i bought a NEW (gasp!!!) Weatherby Mark V Weathermark LT.

Set up thus far has included an EGW one piece 20MOA base.
Vortex Viper low rings.
Burris Fullfield E1 scope with MOA reticle.

Mounted the base with a couple drops of the green Loctite usually used for bearing races under it. (Ensures no air gap)
Screws tightened to 20inlb with the Purple 222 Loctite.
Scope leveled & rings tightened to 18inlb with purple loctite.

Then i noticed it....

The lack of gap between the scope objective bell & the base.
Note, the 9 lug actions are LOOONG!
Along with any coresponding one piece bases!

Moved the scope about 1/8 inch forward. All i could get without interference to the magnification ring.

Loaded up some old (some have green corrosion) Hornady 162gr Competition bullets a friend gave me as they no longer shoot 7mm.
For powder, i used a middle charge of RL19.
This combo was used just for barrel break in.

Zeroed scope with first 3 single rounds between cleanings.
Decided for first group of 3 to try with just the thread protector.
OUCH!!
This baby's got some recoil!
But 3 rounds touching.
Screwed my $1,800 muzzle brake back on (the gun comes free with the purchase of the brake).
Next 3 rounds touching again. No POI change.

Got some medium Vortex Precission rings. Will mount today.
Next shooting, hopefully Sunday, will be ladder testing the 175gr ABLR over RL26.
Still haven't gotten the RL33 to try.

I demand pictures of this beaute.

Glad you got a good one
 
One thing i did notice.

The bolt throw & opening in the action are short.
Put a bullet in a fired case to find distance to the lands with a 175gr ABLR.
Had to remove the bolt to get the round out & measure it.

For anyone not familiar with the Mark V, there is no separate lever to remove/install the bolt.
Move bolt to the rear, pull the trigger & remove the bolt.

So i found COAL to the lands at 3.630".
But i can't get the round out without removing the bolt.
And the thought of having to pull the trigger with a live round attached to the bolt, well lets just say it ain't gonna happen!

COAL to be able to remove a live round is 3.360"..
So a goodly amount of jump.
And a goodly amount of bullet into the case.

Weatherbys have super long throats. I suspect to keep pressures manageable.

Wby have long free bore.

 
Yes, i did know the Weatherby magnums did have a long freebore.
Was just surprised that the ejection port is so short.
I used to own 30-378 Wby and max OACL was 3.648". I'm sure that was build to handle max OACL 3.360". One of guy at gun club has one and his really shoot good and I think he's just loading spec. I shoot 270Wby and it build 700 action. Well good luck
