I plan on getting a 300 RUM and was wondering what brand of bullets and grain everyone shots and is Remington the only ones that offer cartridges for it because I dont reload, in the past I used Nosler Partitions in my 30-06 and like how they performed but the guy at the gunshop said Remington discontinued the partitons because of there new core lok ultras

Federal loads three different bullets for the ultra mag. A 165 grain Nosler solid base at 3350 fps, a 180 grain TBBC at 3250 fps, and a 200 grain Nosler partition at 3070 fps.

My choice, provided they shoot well enough, would be the 180 grain TBBC but they are molly coated if that matters to you.

I own two 300ultramags and find them well suited to my hunting conditions.However I would not recommend this cartridge to anyone that does not reload.Factory loads are pathetically mild and do not take advantage of the extra case capacity that this cartridge offers.For those that do not handload(or are not willing to shoot hundreds of rounds per year practising at longer ranges in order to develop and maintain their shooting skills in order to gain any advantage over the standard magnums)I would recommend the 300wsm or 300 win mag.The 300 ultramag offers no real advantage over these cartridges at ranges under 400 yards or for shooters with average shooting skills.I use 180gr bullets in my 300 ultramags.

I have to concur with stubble. for a non reloader, this could be expensive, and it does take practice shooting well compared to a 308win.

I own a 7mm RUM, and I too don't reload. What I learned, is Remington has stopped loading the Partitions bullets. Not sure if this was Remington or Nosler making the decision. The feedback I received was due to the ultra speeds, the partitions were blowing apart. If Nosler made the decision to pull their products from Remington, the same might happen to Federal. Not sure what Remingtons plans are, but I agree for the same reasons mentioned and more, If you don't plan to reload, the 300 RUM might not be your best choice.....

raptor, sounds like someone feeding you a big one. I shot a moose with a RUM and 200gr partition, and was able to find the bullet with 70% wieght retention and stop behind the hide. A partition will hold together a lot better than a Corelok ultra.

What I heard from Remington Ammo employees, is they had an agreement to load partitions until they unvailed thier corlok ultra. This was a cost saving decision. I bet ya if they can get their corelok slugs flying right, they will discontinue the barnes copper solid too.

I mean think of this. You put this money into development and tooling of a bonded bullet. Would you really also sell a completed cartridge with a competitor's bullet. Guess what happens to the development cost of the tooling and R&D of your new bonded bullet?

I shoot partitions and barnes and never worry about exploding.

Bigcountry,
I actually talked to a Remington factory rep at a opening of a gun store, and that is what they told me. What you said makes sence about the development of a bonded bullet and the tooling, but why are they still loading Swift bonded bullets? just wondering...

Well, I believe he did tell you that. But the partition has been imatated and been around since the 60's. Its been shot at high velocity, low velocity. The frontal area might shear off. But I can't see a partition blow up.

If they are anything like my company, they have a stockpile of scrirrocos, and A-Frames in stock, or/and have a law binding agreement with Swift for finite period of time. My company does the same thing. We work with a "competitor" until we have our gear up to snuff. Then the gloves are off. Nothing too uncommon. I will be honest, I have never shot game with the new bonded corlok. But they are going to have a tough row to hoe beating that repetation about them holding together in high speeds.

Take a close look at remington's financials. They are public information. They are streamlining all their ammo lines. Which I believe is a mistake I see alot of CEO's make. I believe it will hurt thier RUM sales, which in turn hurts thier ammo sales more.

You have been fed a load of manure about partitions.I have used them with muzzle velocities of up to 3500fps(7mmstw with 140gr partition) on game including moose and elk and they always retain about 60% to 70% of their weight and offer great penetration.

With today's premium bullets, any one you find commercially loaded for the .300 RUM should work fine. If you can find a copy of the Oct '02 Shooting Times there was an excellent article on the existing premium bullets with just about every paremeter discussed. I've used Federal Premium ammo in a .30-06 before switching to a .300 RUM.
Like the comments above, the 180 grain NP worked flawlessly on the two bulls I've taken.
