I had three factory barreled 270 Winchesters, M700, M70 and a A7. And another wearing a Bartlein barrel.
5 different boxes of factory ammo. 100 yards and an idea to compare the accuracy between factory barreled rifles to a custom barrel.

Remington Model 700 ADL


Winchester Model 70 Classic


Sako A7


Bartlein on a Model 700


The three factory barreled rifles:



The custom barreled rifle:



Results:



It wasn't surprising that the custom barreled rifle shot 4 out of 5 boxes of ammo better then the best factory rifle (0.72" average on 5 boxes). But it was surprising that the point of impact was nearly identical between all the different kinds of ammo at 100 yards with the custom rifle, compared to quite different points of impact with different loads on the factory barrels.

The Remington shot the second best on average (1.07"), the Winchester third best (1.44") and the Sako was last (1.72").

Also, the factory ammo appeared accurate considering 3 out of the 5 boxes grouped near 1" average out of 4 guns.

Also, the velocities quoted on the boxes of ammo were generally in line with the exception of the Remington Corelokt 130 gr which shot only 2905 actual vs 3060 fps quoted.

That was fun.
 
Was this test witnessed?

Personally if a rifle requires dozens of trick moves at the reloading table to get to shoot the rifle wasn’t that accurate in the first place.


Nothing wrong with factory ammo IMO.

Unfortunately it wasn't witnessed, nor was it shot in a stiff crosswind.
 
That’s a great test. More people need to do the same for their rifles, even if it’s one rifle should try multiple brands of ammo. Recently sighted in a rifle for a friend, 300 win mag Remington 700. Barely produced a pattern with black box Winchester Supreme with coated 180gr Nosler. Box and a half later couldn’t define a correct point of impact. Switched to Remington 180gr CL and bingo, 6 shots and done, 1moa. Sometimes you need to let the gun pick the ammo not the latest trick bullets chosen buy the shooter.
 
Surprising how well that winchester grey box shoots. For deer and smaller game it really isnt worth reloading time for the price of that stuff. Generally impressive results on game to with the positive expanding points used. My 2506 and 300wm love that stuff. I was buying it for the einchester brass
 
Hey Buckmastr this was a amazing well done post thanks for sharing ! You spent a lot of time and money. Have a freiend who loves those Winchester cheep grey box ammo
he carefully pulls bullets not to loose any powder and seats new Nosler Partitions for moose hunting

IME some factory rifles will shoot tight groups with any ammo, some won't shoot 1.5" with anything...
 
Not a 270win, but the best groups that I have fired with a factory rifle and factory loads. These are three consecutive groups fired with my 6.5PRC before I had cases to load.

Generally speaking a custom barrelled rifle will out shoot factory rifles... and it should.

I bought a used X-Bolt .270 Winchester with the plan of barrelling it... but first I bought a box of the cheapest Federal 130 grain ammo and shot it. It pretty well shot 3/4 inch groups and the barrelling never happened. It is still shooting under an inch with Federal 130 and 150 grain ammo. You never know until you test them...
 
Its a pretty easy test to run cheap factory ammo through a new gun. If you get any type of triangle looking group, hand loading should be easy. Stringing like that Sako A7 is not what you like to see.
