OK, my 2 cents on most accurate main stream production rifle
having had a gun shop where I sold packaged rifles/scope combo's and or just sighted rifles in for customers that asked for it, I used to shoot a few hundred rifles a yr for many yrs
what I mostly discovered and keep in mind I was using basic factory ammo and NOT fine tuning a load to find most accurate set up
BUT typically the most accurate on average rifles were savage, seconded to rem 700's
if I had 25 of each of rem or Savage, they tended to shoot the most consistent in smaller group sizes (5 shot groups)
when it came to other brands like Ruger, Win, Browning, Tika, Sako Mossberg ,Marlin, TC and the common brands l , they seemed to be very and please take with a grain of salt and I mean NO bash here, just what I noticed! they seemed very hit and miss, meaning either they shot VERY good or didn;t !
when it came to Weatherby's, they were honestly my worse in accuracy on AVERAGE, and I don't; care if they were USA made Germany made or any where else made one's!, I am sure I will offend some with this, but its just what I experienced having shot a few hundred factory rifles and , or many many yrs! AMMO< riffles a yr
NOW I will also say this , I have shot several of each brand(minus Weathertby I was just never able to shoot one that did this on FACTORY ammo) , ) that shot some super tiny groups out of the box with factory ammo
I have also shot some of EACH and EVERY brand that shot some extremely poor groups!
but after a shooting a several hundred factory rifles a yr, my vote goes to Em 700's and the Savage rifles, as a FACT I would maybe even say the Savage brand rifles shot the BEST of all on average
take as you wish I am no brand loyal or brand bashing or pushing any
just what I observed having shot so many!
100 yards off a very good rest with dozens of different brands ammo, rifles and Scopes over a 10+ yr period!
I will also say that over the yrs, I did see changes in some brands, where things that seemed BETTER got worse and vise versa,
I would also say some times it was like pick of the litter, taking 4-5 of same set ups out and having difference results out of them, as in one might shoot sub 1 MOA and rest shoot 3 MOA? or the other way!
when all things were the same, brand rifle, caliber, ammo, scope mounts weather conditions and so on,
when dealing with anything that runs down a production line , things change as they go, from IN spec to what THEY consider OUT of spec
which IMO is what causes things to vary even when dealing with exact same make model
so, my 2 cents,
