Weatherby Nation

Quite often I read in this and other forums where a lot is spoken about a gun not shooting MOA as per factory specification or producing groups as big as 18" and spraying bullets all over the place at 100 yards.
The first port of call in identifying where the problem really lies is "LOOK AT YOURSELF FIRST" before you blame your equipment.
Most problems can be attributed to the shooter himself especially with big boomers that require muzzle brakes and produce a lot of noise and blast.
I am primarily speaking of two namely the 30-378 and 338-378 Weatherbys.
I happen to own both of these Accumarks and have one shooting 3 bullets into the same hole whilst the other shoots 3 into a 1/4" group at 100 yards, so I believe I am qualified in making these and other following statements which I hope will allow some of you guys to start to fully understand the basic requirements for super accuracy.
Recoil and noise are the primary culprits of the intimidation factor that causes most shooters to be unable to group or shoot their rifles accurately because of flinching and "pulling" the trigger instead of gently squeezing it.
All of the Weatherby rifles that I own or have owned are extremely well made but there is still a lot of room for improvement here.
Make sure the barrel is free floating with at least 1/8" clearance all round and this "dollar note" clearance is just not good enough; so open up the barrel channel.
All rifle barrels "whip" during the time that projectile is spinning its way down along the rifling till it leaves the end of the barrel so give the barrel some room to move.
Have the action bedded professionally if you do not know what it means or do not know how to do it properly.
Then have the factory trigger sear lapped by a gunsmith who knows what he is doing so that trigger pull is down to around 1 and 1/2 pounds pull or safer still fit an after market Timney or some other quality trigger that can be set down to a low trigger pull.
Fit the best optics, rail and rings you can afford.
Use factory ammunition only to "run in" your barrel before even attempting to expect tight groups. Then reload your spent cases and start producing some high quality consistent ammunition.
My handload variations are as tight as 5 feet per second with the 30-378 and 8 feet per second with the 338-378 and you need to achieve similar results to these to start getting things in order here.
Then learn breathing and trigger control before you start trying to get those tight groups.
As I said in the opening lines both of my rifles have proven to be and I also believe they are far better than most custom built rifles costing more than double their price.
It just goes to show what can be achieved when you fully understand everything what is involved in making a rifle shoot like mine do.
Starting with a quality rifle and barrel, bedding the action, Timney tigger and learning trigger control, high quality Night Force scope and precision loaded ammunition with those magnificent Berger projectiles. When all of this comes together on the same day it is a fantastic experience when you achieve what would normally be considered as unachievable or impossible for a hunting rifle at the range. Even the bench rest shooters there came over and had to admit they never knew a hunting rifle with a bit of rework could produce such spectacular results.
I hope this helps some of you guys out there not to lose hope with your rifle's inability to group, it might just be you and/or the ammumition you are using, especially factory ammo, so don't blame the rifle.
The Weatherby rifle will do its part, all that is needed is for you to do your part.
Hope this helps, good luck and good shooting.

i've done most of my hunting with my 12,ga shot gun and when i got my first weatherby i wasted a box and a half of shell be for i ask a friend for help after some coaching i learned trigger control breathing how to properly sand bag my 300 wby and after a lot of practice i get wonderful groups my weatherby is a stock vanguard nothing fancy i use 180 gr, noslar partitions and never had any trouble the weatherby 300 magnum is the most powerful rifle i ever shot i would love to shoot a 416,460,30-378, i'm just a nut i guss i love recoil it just takes practice and a very good rifle the rifle is a tool the rest is up to you weatherby the oringinal bone collector

It takes more than a chest filled with shiney tools to make you a mechanic. You may spend a small fortune on the finest rifle and best ammunition and still be an utter failure on the range. Without knowledge, skill, and practice, the finest rifle in the world is simply a bullet launcher.I will believe corporations are people when Texas executes one.

The finest rifles, still must have an experienced, trained rifleman, but; the best rifleman, can only achieve to the limits of any rifle/load. Poor equipment only sets poor standards, poor training only exhibits poor performance, and all the talk in the world will never change that fact.
The best riflemen are constantly ON THE RANGE, using the absolute best equipment/loads they can get put together, ....observing the wind/conditions, working the terrain problems of HIGH/LOW angle shooting, doing the shooting drills/positions, evaluating their shot placements/grouping; in the attempt to achieve a performance that never seems to be good enough for them.  In short, they produce CHAMPION performance because they put forth the superhuman effort demanded.
DARE TO BE ONE OF THEM!Kristian Selous

Couldn't agree more with the ...."practice makes perfect"....phrase.
I once read where someone wrote that only one in every thousand shooters will ever master long range shooting to 1000 yards and over.
You must/should practice in all conditions mentioned in previous posts before even attempting to take the rifle into the field to harvest an animal at long range.
You owe that to the animal involved.
