Home Forums Hunting & Shooting Elk Hunting most accurate .300 Win Mag FACTORY load?

I haven’t found any factory loads that don’t shoot under an inch out of my Sako A7. 😁

Every rifle is different, so you won't know the most accurate one for your rifle until you test them all. But how accurate is accurate enough for you? Once you answer that, I'd still test a number of factory loads in case your favorite gets scarce. I'd start with the cheap stuff since it tends to be the easiest to find.

Several years ago I bought some Norma factory ammo featuring the Oryx bullets. At the time components were next to impossible to find, the Obamanation years. Bought the ammo mostly for the brass but have been pleased with the performance. Of course you may just have to go with what you can find. These came from MidwayUSA and I was on a waiting list for quite some time but was in no hurry so could afford to wait.

I would love to find some precision hunters for my 300WM

That’s where I’d start. If 180 Accubonds don’t shoot I’d try 180 Partitions next.

I have two very experienced friends who love the Barnes Vortex 180 TTSX in their Sendero 300 WM. Even for deer.

My Kimber Montana in 300 Win mag. Was very happy with these loads.
And by the way, rifle is for sale.

My Tikka 338 win mag loves Barnes 225gr TTSX.

Barnes 180 grain TTSX in my 300 wins have always been super accurate. Never tried anything else.

Last year I used 180gr Federal trophy bonded tipped on a nilgai. Very accurate in the Remington 700 sps i bought just for that hunt because the outfitter insisted on a 300 win mag. High shoulder shot, nilgai collapsed, bullet was a pass thru. You might give them a try.

Many are plenty accurate for most hunting. And unless you've spent plenty of time and resources on practicing long range, just don't.

The .300WM with 200gr partitions is pretty tough to beat both performance and accuracy in mine. With that said though, the 200gr ELD-X, or similar would be fine.

If you do the math for how far you plan to shoot, half the size of the vitals, you'll know how accurate your choice will need to be.

180gr TTSX .72 inch group at 100yds. dead elk no bullets recovered enrtance and exit holes

have had great accuracy with 180 grain accubonds and they work great on elk, moose and mtn goats

Really amazing that most are not referencing FACTORY loadings

It amazes me that people don't know you can take 5 boxes of about any commercial brand ammo with the same type and weight bullet, shoot them all in the same rifle, and most of them will have a different POI accuracy.

Nosler 180 Accubonds or Barnes 180/165 TTSX is where I would start.

I have no input,, other than I realized that I have owned and shot my 300 WM since 1988 and cannot ever remember firing a factory round. There are a couple of unfired boxes of factory ammo on the shelf as well as a couple 100 pieces of new brass., and several hundred bullets, but not one fired factory case. ?

I bought a new Weatherby in .300 mby. mag. about 20 years ago and shot both 180 and 200 grain weatherby factory ammo in it and they were both sub minute groups. My latest and favorite have been 180 grain Swift Scirocco and they are the same. My rifle was not glass bedded when it was new of course but it is now. That didn't seem to improve it but it might yours if it's not. I realize you don't have a wood stock but even at that it might help.

You dont want to spend $1,000 trying to find the best reloads? I wouldn't neither. However, if you can even find so much as 5 boxes of factory loads your cost will surely be $300 anyway. I have always found little difference in accuracy in my reloads. Seems a good barrel shoots everything good enough for hunting.

Winchester Model 70 Classic Stainless 300 Win Mag: Federal Blue Box 180 Grain Gave me 5 shots in an inch square on the target, waited for the barrel to cool down for 30 minutes, put another one in that 1" group.

Ruger M77 Mark II 300 Win Mag, Shoots the same federal blue box 180's to around an 1", but I can get well under an inch with Fiocci 180 grain. I believe these are loaded with Hornaday bullets.
