Whch factory does your rifle shoot best.
 

My Ruger M77 270 1moa with 130 remington core locs

My own brand. I reload for all my guns.

My 2 favorites are:
7mm Rem Mag likes 150grn Sierra GameKings
.223 like Sierra 55gr BlitzKings

Rem 700 loves rem 150gr core lokts. Ive only shot federal and winchester in the same grain, so I can only compare to those.

My .270's (Remington and Tikka), both shoot 130 grain Remington Core-lokt's well. Plus, it's loaded light so that the point of impact is the same as their 150 grain .270's.

From my experience, the pointier the soft-point (inexpensive ammo), the better balanced, and more accurate it will shoot. 130'swill group a little tighter than 150 grain soft-points, from any manufacturer.

Anything with SOME quality is worth a try for factory. I've had wolf gold shoot great, and I've also had more expensive Federals and hornady shoot great. But none of them can roll with a handload :D

I shoot handloads but most of my rifles shot Remington Cor-Lokts the best when I shot factory. Except my M700 in 25-06. I would only shoot Winchester 120gr PEPs well. But it shot them into 1/2" groups. Go figure.

My M700 .243 Win really likes Hornady Light Mag 100 gr BTSP and Winchester Super-X 80 gr PSP, so much in fact that they both shoot better than my handloads, but to me, shrinking my groups from .4" groups to .3" groups @ 100 yds isn't worth paying 2 or 3 times as much per round.

my model 700 .270 win shoots hornady light mag 140 at moa, and remington scirocco 130 at almost moa.

my 700 in 243 likes rem core lokt or win super x(1 1/2'' groups,good enough for deer hunt n)

My 700 XCR in 270wsm shoots Winchester Supremes well.
