I'm far from a seasoned rifle man so looking for some recommendations on a good ammo choice for a Browning 300 Win Mag X-Bolt with a muzzle break.
My primary purpose will be to use for big game. I want to use the right ammo for all my hunting situations as well as getting it dialed in on the range.
I realize this is a fairly vague question, but I figured this forum would be the best place to ask the question from real hunters with experience in the field.
I have reviewed information online but there seems to be many many options out there so I obviously would like to narrow them down.
Again primarily will be used for Elk, Mule deer.

Thanks for all the help it is very much appreciated.

Anything with Barnes bullets will be good. I'd go with the 165 or 168 grain, more velocity, less recoil than 180's. And thats the nice thing about the 100% copper bullets- the faster you push them the better they work. They won't disintegrate when you hit a shoulder and destroy half a deer.

If your rifle won't shoot the Barnes bullets well, try Accubonds. I'd go with 180 grain with these.

Honestly any controlled expansion bullet will work great for you. You need to find what your rifle likes by testing some of the readily available stuff on the market. I am a Hornady interbond fan but I have seen great performance from Barnes, Nosler, Remington and more.. The reason there is so much information and so many opinions on the web is because there are many correct answers. A 300 win mag is a great caliber with many great manufacturer/bullet options.

You have already been given good advice. Monolithic/very high weight retention designs like Barnes X's like to be pushed fast, 165-168gr is a sweet spot for them in a 300 mag. Traditional cup and core and most any bullet designed to shed 25-50%ish of it's weight tend to work better with more weight so 180gr is good area to be. If you go the match bullet route, Bergers/SMK, think very heavy 190-210gr is what I'd use were I to try them. All that said, for what you say you are going to hunt, a 180 bonded or partition style or mechanically locked style is where I'd look.

Accubonds are excellent bullets. I have used 165 grain for years and we have killed sheep, antelope, deer and elk with it. I am in the process of moving to 200 grain for a better ballistic coefficient to extend my shooting range.

I had a Browning A-Bolt with BOSS in 300 Win. Mag. I shot a lot of different factory loads and a few reloads, and found the best shooting load (in my gun) to be 180 gr. Accubonds. These were factory loads, but sold the rifle a few years ago (too heavy for backpack hunting), and forgot the specific ammo manufacturer. Anyway, I shot two big mule deer with it, both at 263 yards. In both cases, the deer was knocked down, rolled over, and DRT.

My 300 A-Bolt shoots 180 Winchester Ballistic Silvertip Ammunition very well. I would try a few different bullets to see what your gun likes.
