I don,t know, several factors, like if your scope is of decent quality, if the ammo was decent quality, the bullet weight, the rifles twist rate?
if the barrel was carefully cleaned before you went to test the rifles accuracy,
and not knowing how well you shoot,
the range you shot at, the targets you used,(yes this can be rather important.)
the type of rifle rest , how your scope and mounts were mounted,
Id have too assume you got all that correctly set up.
if everything you used was correctly set up, and its truely the rifle,
you might consider checking out the rifles action bedding, check action, screw tension for example.
, and you may want too consider epoxy bedding the action on any rifles.
almost all rifles seem to prefer some brands of ammo and some bullet designs over others.
youll want to try several brands and bullet weights.
most out of the box, O.E.M. rifles accuracy can be improved noticeably,
carefully cleaning a rifles bore from the breach end and allowing it too cool between every 10 shots or two 5 shot groups. on a new bore helps accuracy.
weatherby vanguards are generally very accurate right out of the box if carefully cleaned correctly prior to use.
theres a great many potential problem areas, that need to be checked before assuming the rifle it self is not all that accurate.
scope mounts and scopes are a rather common source of less than impressive accuracy.
Ive got one 300 mag that loves 180-190 grain bullets with almost any loads,
but if you use a 150 grain groups tend to open to almost 2" at 100 yards,
off the bench at 100 yards while the 190 grains generally group under 3/4" if I do my part.
another 300 mag loves the 165 grain weight but is less tolerant of the 190 grains
all rifles have minor differences in machine work, clearances/tolerances
and ammo components and powder chemistry varies
,between batches and manufacturers.
as will load density, the barrel harmonics change with pressure and projectile weight, so some loads,
will be more consistent and tend to provide much more stable/consistent accuracy.
its very common for a rifle too shoot one or more bullet weights or ammo from one manufacturer,
far more consistently than ammo from a different manufacturer,
thus youll need to try both different brands and projectile weights/
most 30/06 rifles shoot the 165-180 grain weights rather well,
Correctly bedded rifles are almost always much more consistent.
Ive had several rifles respond amazingly well from being re-bedded in epoxy and having the muzzles re-crowned

if you cam borrow or purchase a rifle rest like this and throw a 25 lb bag of bird shot on the tray, put in ear plugs and wear ear muffs ,
and then try shooting a couple groups you can eliminate recoil and muzzle blast as potential sources for flinching as both the recoil and noise will be eventually eliminated
a significantly cheaper but less effective option,
lots of guys prefer to use "SAND BAGS" for a rifle rest , these can be fabricated cheaply from old dungaree legs,
or bank coin bags if you have access to a sewing machine and you have minimal skills using it.
(yeah! ideally the wife or girl friend who may be more skilled with a sewing machine can help)
commercial sand bags, for rifle range use,
tend to be expensive and many people
buy them without realizing most are shipped empty.
most guys are reluctant to fill them with actual sand,
because its both heavy and it absorbs and holds moisture,
almost insuring that mildew/mold over time ruins the bags, or they can leak sand in your home, car, or storage area.
yes I'm well aware that many guys fill zip lock plastic bags,
then, double bag and insert the zip lock sand bags inside the canvas coin bags, to reduce the tendency,
some guys use uncooked rice
(this can attract vermin)
or packing peanuts
(too light and compress over time making the bags nearly useless)
the larger 12"/19" bank coin bags tend to work rather well

stuff the bank bags with rubber mulch filled zip lock bags with a 2.5 gallon zip lock bag filed with rubber mulch which is basically fine ground up old tires ,
and you have bags of the correct weight, firmness and these won,t attract vermin when stored,
get the correct fill percentage that allows the contents to be partly redistributed, the contents,
so you can manipulate the height/thickness and then fold the open end of the canvass coin bags and sew or staple shut.
a couple of the larger size coin bags , (bags of the rubber landscaper mulch) used to support the rifle, , under the forearm, one partly under the butt stock, with most of it between your shoulder and the butt stock, to spread and absorb recoil, will also mostly mitigate recoil
