First time reloader! Will be reloading 300 Win Mag. Recommendations for a great Elk hunting load to start my load development with?

I came up with a great load using 200gr Accubonds and H4350 out of a 22'' gun running 2815, should kill anything dead I need too as far as I can shoot!

You probably aren’t gonna like your press mounted under that cabinet. You also need manual balance scale to double check that charge master periodically.

Also, if you aren’t aware how headspace is measured on belted Magnum cartridges you may want to study up. In most factory chambers there is a country mile of space in front of the shoulders because they headspace off the belt. You will probably need several firings before the shoulder is fully grown and can be bumped back reliably.

As for a good load, no one can tell you this. Every barrel and every chamber is different. Consults a good reloading manual, start low and work up slowly and safely you will find your own sweet spot.

Set-up looks good. If you are anything like me, it will be cluttered up with all sorts of additional tools, trinkets, and trash before too long.
I don't reload for the .300 Winny, but if your rifle has a particular brand of ammo and bullet weight, it shoots well. I would suggest you start there. Focus on the bullet weight and velocity numbers to start, and then find your load data in the correct loading manuals. I cross-reference at least two different books or sources to get my starting loads. I also try to find like bullets that are cheaper to do my ladder work-ups (Speer hot-core, factory seconds, etc), then use the premium bullets sparingly for load development and hunting specific uses.
If you are truly starting from scratch, then I suggest deciding on a bullet weight range to focus on as your goal. If uses are only elk, then probably 180-200 grains and a more premium bullet. Follow the same strategy as listed above.
Best Wishes, it is a fun rabbit hole to go down.

H1000 and Berger 215’s are a pretty easy button for the WM. My loads settled in at 75.1 grain of powder, CCI 250, Berger 215’s set at .025 off and shooting at 2884 fps. It’s a tack driver and has yet to have an elk take more than a couple steps before tipping over.

The press won’t actually be located there. I’m using an Inline Fabrication Quick Change system for my press and case trimmer. The bracket on the wall is just a storage mount for whichever tool isn't currently in use. Here is a photo of the press mounted for reference.

I appreciate the advice and will definitely read up on headspace; I have the Lyman 50th Edition manual to use as a reference. I wasn't aware of the requirement for a manual balance scale, but that makes sense. I did buy some check weights—are those sufficient for now?

Appreciate the advice!

Do you have a recommendation for a second book? I currently have the Lyman’s 50th edition.

Bingo. This is all the info you need.

Gotcha. Thats pretty slick. Personally, I would not reload using an electronic scale without a balance beam too, but that’s just me.

I have several reloading manuals (Nosler, Hornady, Speer)... These days, I use the load data I can find online for specific powders and bullets. I screenshot and print them so I have hard copies in the back of my reloading log.
I only use the Lyman book for shotshell recipes. I like the Hornady manual because that is what I shot for years, but I would go with whatever bullet-specific manual you think you will most likely load.

I've loaded 7mag and 300 win for years. H1000 and H4831sc have been good to me. I prefer 180 accubonds for the .300.

IF you have a 1:10 twist in the 300 you might have trouble with the 200+ grain bullets stabilizing.
My favorite load for the 300WM has been 180 Accubonds with H1000 at 79.0 grains. It is a winning combo for sure.
