Finding the right factory load

Guys,
I'm trying to find the 1) most accurate factory load 2) for my rifle 3) to be used for elk and deer hunting. The rifle is a Browning A-Bolt in 300 WSM, with a factory standard 23-inch barrel.

My maximum range is currently about 350 yards, which I'll be happy to try an extend when I complete my training for the 1760 yard range, and take up hand loading.

It appears that Federal and Winchester together have 21 different loads, and there are at least nine other manufacturers with 18 more loads. I don't mind shooting a lot but I don't particularly want to waste much energy on either known losers, unnecessary gimmicks, or duplicate loads.
* I think I can exclude the lead-free loads as unnecessarily exotic (e.g. E-tip, Power-Core, AccuBond CT, Trophy Copper).
* I think I can exclude 150 grain loads for elk (I know shot placement is king, but let's use the 165 or 180 elk load on deer and reduce the search parameters?)(unless of course a 150 happens to be the most accurate load, then I'm toasted).
* I'm think that I can exclude the 190 gr and 210 gr bullets too.
* Maybe I run these loads if the more standard stuff ?just doesn't do it.?

So that still leaves 21 factory loads by Winchester, Federal, Armscor, Barnes, Colorado Buck, Cor-Bon, HSM, Norma, Nosler, and Remington.

With bullets called: Power-Point, Extreme Point Polymer Tip, Ballistic Silvertip, Ballistic Tip, Partition, Accubond, Power-Max Bonded, Fusion, Trophy Bonded Tip, Power-Shock Soft Point, Tipped Triple Shock X, BXR Rapid Expansion Matrix Tip, T-DPX, Berger Hunting VLD, Oryx, and Core-Lokt PSP.

Can you guys recommend other characteristics that might help reduce the number of boxes of ammo that I need to buy?

I understand that hand loading is ultimate process for finding the perfect load. I'm working on baby steps at this time.

Nosler custom ammo in the 165 or 180 accubonds or HSM 168 or 185 bergers is what Id try first.

I've had Federal Fusions shoot very well and kill the heck out of antelope, deer, and elk if money is a concern. A box is about as cheap as you'll find for the 300 wsm.

I shoot the Winchester 180 grain ballistic silver tip ammo they shoot the best I've found out of my Remington 700 300wsm I can shoot a 1.5 inch group at 200 yards that's good enough for me! They are $39.99 a box at Walmart! I've shot a bunch of factory ammo etips Barnes ect & they shoot the best for me! And I've never seen anything I've shot go over 20 yards when shot!

It doesn't have to be that complicated. Start with some type of a partition load and if that doesn't work, move on the next choice until you are satisfied with the accuracy. I just don't see the need for target rifle accuracy in a hunting rig.

Over the years and many rifles I have found that Federal ammo loaded with the Sierra bullet or the Nosler Partition gave the best accuracy in many different rifles.

You will want the Nosler Partition for a elk bullet. I know Federal loads the 180 gr. Nosler Partition in the 300 win. mag, and you will have to check if they load it in your caliber.
