I will be elk hunting this year and not sure what caliber to choose. I have alway been a huge fan of the old trusty 300 win mag but last year I bought a 300 rcm. Any thoughts on that caliber? Was it a mistake to buy a short mag?

IMHO any of the .30 cal mags will do the job. How much have you shot it? Do you reload or use factory ammo. What rifle and optic?
The advantage to the Win mag is lots of them around, lots of reloading data available and ammo easy to get....and oh yes, they do shoot!

I Have shot it prob 100 times, it is a ruger m77 hawkeye and shooting factory load. I have a vortex diamondback 4x12 with the Bdc reticle . I want to get into reloading after I get back. It is somthing I enjoyed doing with my dad as a kid and would love to start doing it.

If it were me, I would pick the lightest rifle of the two. Rugers are pretty heavy compared to tikkas, brownings, remingtons,etc..

I already own the 2 rifles the other I bought a few years ago. It is the Remington 710 300 win mag. It is light but it is a cheap rifle and not sure how dependable it is. I have taken many animals with it and it has held a good group for a cheap rifle. One of my main concerns is if the 300 rcm is going to stick around or is it going to fade away. I guess time will only tell.

I shoot a Remington model 7 in 7mmSAUM. Remington only sells one load for it now. They stopped selling rifles in this caliber so I have to handload ammo for it if I want to find what the gun likes. It's a pain when you can't find ammo for your rifle. I went and bought 200 brass cases so I should have enough to load for years to come. If it becomes impossible to get ammo or brass I'll have it re-barreled.

I have the same issue with my .300 rcm only hornady makes loads for it, I bought a 100 rounds for it while they were available. Worst case I will have it re-barreled like you were saying.

As long as you can find or load ammo, either of them will do the job. Despite personal preference and all of the hoopla over which one is the best, there is little difference in the accuracy/killing power of any of the .30 Magnums. I have owned and killed animals with the .308 Norma, .300 Win., .300 WSM, and .300 Weatherby. With similar shot placement and bullets, all were effective on elk and deer, and all were plenty accurate for hunting rifles.

Those are very good points, i have decided to go with the .300 RCM. Hopefully i can give it the chance to do work in a few weeks!!!

It ain't what you use. It's how you use what you use. Yesterday morning a guide told me while he was quartering an elk that he'd much prefer one of his hunters use a .270 Win that he can shoot as opposed to a magnum that he can't.

Keep in mind that nothing lives long without its heart and or lungs. What destroys that ain't as important as that they are destroyed.

I have an old hunting buddy who bought a Remington promotional rifle many years ago. That rifle didn't know that it was on the low end of the price continuum because it shot like a high end rifle.

I think the 300 RCM's and 300 SAUM's only downfall is they are so similar to the 300 WSM and there is alot more factory support for the WSM. There are alot of calibers that are great calibers but they never got very popular because they were to similar to something else that was already popular. The 25, 30 and 32 Remington are every bit as good and better in some ways then the 25-35, 30-30 and 32 Win SP they were designed to compete with but the Win's were already popular and the Rem's never got very far. If you are happy with the factory ammo you can get or want to reload the RCM and SAUM are every bit as good as the WSM.

Musket Man,

I agree. And I think that the .35 Rem might have slipped your mind. As pedestrian a cartridge might be, the .35 Rem does work as intended.

No it didnt slip my mind. I mentioned those because they are nearly identical other then the Win's are rimmed and the Rem's are not. The 35 Rem has a different parent case and was pretty successful. There also wasnt a nearly identical cartridge to compete with it when it was introduced, which was the comparison I was making to the 3 300's.

Hi Musket Man,

That makes perfect sense. I didn't categorize your listed cartridges by rim. Once you've pointed it out to me, it fell right in to place.



Thanks,

SS

It is kinda interesting that the 6.8 SPC is based on the 30 Rem case, shortened and necked down to 277. The next AR I build is going to be a 6.8. Part of why I chose it is because its based on the 30 Rem and Im kind of a 270 fan! I have a 32 Rem in a Rem 14A pump action. I have never shot it much since ammo was so expensive but now that I have started reloading I will be shooting it more.
