Recommend a good bullet weight...

...for a 1x10" 26" barreled 300 winmag. I have a Remington Model 700 Sendero SF II and I'm looking for some accurate factory loads. Now I know in .223 or 5.56 the lighter bullets seem to prefer slower twists such as 1x12. Does the same hold true for thirty caliber rounds?

Heavier bullets prefer faster (tighter) twists...

And with a 10 twist barrel you can shoot all the way up to 230gr.

Re: Recommend a good bullet weight...

yes, it holds true. heavy projectiles need a fast/faster twist, the lower the number the faster the twist. 1:10 twist is slower than 1:8

for examples of what your barrel might like for the twist you have, look up a barrel makers website, they often have guide lines.

Use this:
Barrel Twist Calculator

The length of the bullet for caliber as well as velocity is what's important to calculate the twist needed to stablize a given bullet.

Where weight comes into play is usually longer bullets are heavier than shorter bullets for caliber.

You need to post more data: How far? What is the target? Where are you hunting (both long and short shots or more one sided)?

Good news: Lots of quality ammo for 300 WinMag.

Factory stuff I would look at: Nosler and Barnes factory ammo with their bullets. Barnes 150gr TTSX is pretty flat shooting and will work up to elk. Not my first choice for elk but it works. Nosler turns out some of the best stuff out there. 200gr Partition from the 300 WinMag will hammer an elk.

If your shots are going to be < 600yds then factory ammo will cover it. But if you stretch that pretty much you're going to be told to start reloading.

Two things you need right away is a quality laser range finder and a chronograph. The range finder is standard equipment these days and rightly so. The chronograph comes before any reloading equipment (in my book) because you need to know the velocity of your ammo to dial in the ballistics programs. There are a ton of good free Ballistic programs on the web. Chronographs are available on sale for less than $100. Absolutely no reason for hunters not to own a chronograph these days!

FYI: I have never had factory ammo deliver the exact velocity they claim. Mostly less, some A LOT less, can't remember any shooting faster. I've owned a chronograph since the first Shooting Chrony. The one when there was only one model and it didn't have a memory or calculator. Used a notepad to record velocities and did ES & SD when I got home to the calculator. This was before PC's.

It was the best investment I ever made! And they cost less today!

I guess I'm looking for more of a "in general" answer. At $30+ per box of ammo, I just don't want to waste money on factory ammo that won't be as inherently accurate as something of a different bullet weight. For instance I bought two boxes of Barnes Vortex 180gr. rounds a few weeks ago because they were there. Right next to them on the shelf were boxes of that new Hornady American Whitetail in 150gr for about $12 less per box. I don't mind paying more for the ammo if it's going to be more accurate. In fact, I know the buzz on Federal GMM and can secure boxes of them at $52 a box. But I don't want to bother if they'll be inaccurate out of my rifle. The rifles main purpose is long range hunting but all shots would be under 600 yards. I hope I made this a bit clearer...

Re: Recommend a good bullet weight...

Honestly, the price of a bullet isn't necessarily going to dictate how accurate it is going to be in your rifle. Every rifle is different. Someone could have great accuracy with one factory load in their gun and you could take the exact same model rifle and that load could shoot terrible. Your best bet is going to be trying multiple different loads and brands. You don't have to be too picky since you will only be shooting to 600 yards, but I would still try to find heavier, higher BC bullets, if possible. The number of factory 300 win loads that are available are endless. The best thing for you to do is try a few and see what works best, then load up on a bunch of them from the same lot, if possible, and begin to shoot and figure your drop charts.
