300 RSAUM ??

**RBELARDI** · November 13th, 2017, 09:20 AM

So I bought a Remington model Seven chambered in 300 RSAUM.
I'm guessing the gun is 10 years old due to the caliber being discontinued years ago. Its in great shape. I bought it relatively cheap.

Anyone have any experience with this caliber ??

Anyone have any good reload combinations ??

Thanks

For those of us not familiar with this round,what does RSAUM stand for ?

Oops Sorry

Remington Short Action Ultra Magnum.

From what I read it was supposed to be the competition for the 300 Winchester Short mag but never really took off like the WSM did.

AHA ! There are no dumb questions in life,good luck with your new purchase.

Thanks, I haven't shot it yet due to a lack of availability of ammo. I guess when Rem. stopped making the caliber the ammo dried up as well. I could purchase it from Midway but since I reload I just bought virgin brass and a set of dies. They will be here tomorrow.

The ballistics look impressive in Nosler's Reloading manual. I almost bought a Remington model 673 in this caliber a few years ago but I have a couple of 30-06's that I load for and the gain in velocity with the 300 RSAUM just didn't seem enough for me to get it at the time. Good luck with your purchase hope it's a good shooter for ya.
