Having a hard time getting any factory ammo to group descent in Browning 300 WSM Hell's Canyon Speed. Obviously I trust the mounts and scope. Wondering if anyone has the same set-up and has a descent factory load that works well for them. I appreciate the help. Looking to stay away from handloading. Best I can do now is about 2" at 100 yards with Barnes Vortex 165 grain.

I would start here. Possibly hornady precision hunter but federal premium has not let me down in any of my brownings. Friend of mine shoots these in a X bolt pro and they are sub MOA to 450.

1. Go to ammo store.
2. Buy 1 box of all 300 WSM ammo they have.
3. Clean bore to bare metal.
4. Borescope it for obvious defects.
5. If #4 is okay shoot 5 of box #1
6. Repeat #3
7. Repeat #5
and so on.

If nothing shoots moa, have someone else do the drill.

I assume all screws are torqued properly and the scope is known good ?

Have yet to meet an A or X bolt that were not very accurate.

Seems to be a 1 in 10 twist rate
According to Browning's website that rifle of yours has a 1:10 twist rate.

Unfortunately it'll be trial and error. You'll have to buy various manufacture, bullet weight and type and try them out before you find that sweet spot of groupings that you good with.

I tried 4 different manufacturer's, three different bullet weights and several bullet types; SP, JHP, BT, BTSP, FBSP and BTBT before I found a round that groups well out to 400 yards.

Now I have all this ammo left over...

Yes, it is a process and its going to take time and money. Add to this list the expected distance you're going to shoot not the distance you'd like to shoot. Also add steel targets at 750 meters or deer/elk at 250 yards. The answer will most definitely determine which style of bullet you end up with.

If you're shooting at steel plates don't worry about expansion...

I don't own any WSMs.
In old fashioned cartridges I own 10+.
Never found one that won't shoot MOA with several brands of factory ammo.
Progress a'int always progress.

I have an Xbolt Hells Canyon Speed in 300 WSM. sorry to say I spent a small fortune (money and time) trying to find a load that will shoot. Tried all the factory brands and like you, didnt find anything that would consistently group. I handload, so I went through that whole process as well. I also had to up my reloading game significantly with a better scale and redding dies. I finally landed on 200 Gr ELD-X, w Nosler Brass, H4831SC, and 215GM primers. i also upgraded the trigger to a Timney as the stock trigger was factory set over 5lbs, and would not adjust below 4lbs....lawyers trigger spring I think.
I just brought home my 6x5 bull elk from the Northern BC Rockies that dropped at 745 yards, so some proof the gun will now shoot.

i would look at the trigger first because 5lbs isnt going to help w accuracy.

I had great results in a custom built 300WSM with Hunting Shack's factory ammo. 1/2 MOA all day long. You might want to try a box. Competitively priced and very consistent.

If this is a newer rifle, I’m not shocked to read about problems with a browning. I sure hope it’s not like the others I’ve read about, or the one I had but, I would consider trading it off and buying something else before you’re too close to season to make a rifle change.

Mcarbo trigger springs are a quick fix.
I tried one before I put in the Timney. Easy install.
Initial trigger setting was at 2.5 lbs, but then it started to get erratic creeping up over 3lbs. The Loctite did not fail so the screw didnt move.
I think it was the Browning trigger because even after I took out the spring entirely, trigger pull was now closer to 4 lbs.
Not blaming the MCCarbo spring, but I was fed up and just went Timney.
2.5lbs all day long. I did lose the Browning bolt lock in the process as Timney doesnt have one.

I had an X-Bolt 300 WSM 10 twist S.S. Long Range Hunter. I ran a box of Federal Fusion 150s they shot very well. But also ran HSM 168 VLD they shot just as good as my hand loads with Nosler bullets, 150 BT, 180 BT and 190 ABLR. All 1/2 Minute or better
