A friend wants me to show him how to reload for his elk gun. I've never loaded a belted magnum round and wanted to ask if there are any special considerations.

He was looking at the X-dies on clearance at Midway - opinions on those?

Also - I was considering Reloader 22 because I am familiar with that from some of my heavier .30-06 loads. Looks like a winner for the .300 Win Mag, but I'm open to hearing your opinions.

Last but not least, he seems to want a 165 grain bullet, and if I'm hearing him right, he's shooting Hornady's SST now. I'd think the 165 interbond would be better for elk, and I've always leaned towards 180's for the wapiti. Thoughts?


Please help me and my friend save some time, money and trouble if you have a proven winner in this cartridge.

Don't be throwing around the term 'Wapiti', flatlanders have no idea what that is. (You probably had to look it up.)

300 mag for elk? Seems just a tad excessive doesn't it? :dunno:

With the newer bullet designs like the bonded ones you can use lighter weight bullets. I think the SST falls in the "newer", tougher category. The US Navy got best accuracy using IMR-4350, loading 180, 185 and 190 grain bullets. Later they went with a long-loaded 190 grain bullet and RL-22. They now have a new and improved 300 Win Mag load for Special Forces. It uses an even heavier bullet.

Jack, I learned the "W" word about 10 years ago, when I decided to climb out of the primordial soup that is the flatlands and become an enlightened Coloradan.

Lotsa fellas go after them with .300's these days. Not my choice, but it kills 'em dead for sure and you can certainly reach out a bit further...

I would go with a heavy bullet personally. If you want to shoot a lighter bullet, why bother with a 300 and the recoil? A 270 would be better.

Wow. Any info you can dig up would be appreciated.

Standard dies work OK. No need for anything fancy.

There's a lot of great mag rifle powders nowadays. But I'm old school and still like a 180grn. Nosler Partition over a healthy dose of IMR4350/4831 for all around .300 WM use. Plenty of accuracy and more then lethal enough for anything on the N.American continent.

The wapiti used to be a plains critter...

This may or may not be true... I don't trust a thing you sub-standard people say.

I do know for a fact that 'Wapiti, (I've seen it spelled, Waapiti) is an American Indian word. I learned this very early in my youth while studying my culture... well, part of my culture.

I'm actually half Italian and half Indian... I'm Awopahoe.

My father was Siouxcillian. And you thought a loading forum was just about bullets. HA!

I shot a deer in the head last fall with a 180 gr soft point from a .300 Win Mag. The results were impressive.:supergrin:

I'm guessing that one is not mounted on your wall...

You fellas using magnum primers? I'm seeing data with both kinds, but I think I understand the use of a mag primer in this round.

The SSt is NOT a bonded bullet. If you are going to push bullets faster w/ a magnum, then bonded or premium bullets would be my choice. I would also prefer 180gr in any 300mag. RL22 works, I like IMR7828 a bit better, it seems more stable form lot to lot. H4831sc is also a good choice as are several others. Partial FL or neck size for best brass life & accuracy w/ any belted bottle necked round.
Mag rpimers, maybe, depends on powder choice. I tend to get better accuracy w/ medium burnrers & std primers (IMR or H4350, 4831 or RL19). When you go slower, you may get better results going to a mag primer. Load some & test is the only way to know for sure, every rifle is diff.

I can't help you with loads, but I would consider the Lee collet die. It only touches the neck, and squeezes it in a collet. No issues with the belt, shoulder etc. I use it in 30-06 and I got sub MOA at 100yds with my $250.00 Stevens 250 and the only load I tired in it.

Yep, mag primers.

Magnum primers can help lower ES with the slower powders.

I am using Federal Magnum Match.

With medium burneres, they can actually cause greater ES. I ran sime test w/ my extremely accurate 260ai. Found a good load using Fed match priemrs then loaded identical laods swapping primers out. The accuracy w/ CCI mag primers was worse, but the RP were the same. Every rifle is diff.:dunno:

I've been loading 165's in my two .300wms for over 15 years. My favorite load is 79 gr RL-22 lit by a Fed GM215M primer and a Hornady Interbond. My Sendero likes lighter bullets and the bonded ones hold together and don't destroy as much meat as the older designs did.

I'm also a fan of 180 grain Nosler Partitions over IMR4831.

The powders and bullet weights the military ended up with for accuracy and pressure are IMR-4350 with a 180 grain bullet, RL-22 with a 190 grain bullet and H-1000 with a 220 grain bullet. The military 300 Win Mag loads are loaded longer than SAAMI maximum length at a length of 3.450" to 3.500".
