Re: .300 Norma magnum for hunting??

Shooting a 26" and H50bmg, I have been using 2850fps totrue my ballistic solver and 230 grain OTMs. At 2300 ft. I'm holding 7.5 milsof elevation for 1100 yards. The 300 RUM is a power house, no doubt, and I have seen its capabilities on Dall sheep here in AK.

I just haven't shot a cartridge that I like better or feel more confident with at or past 1000 than the 300 Norma. I had been shooting 338 Lapua, decided to try a 300 Norma, and I'm glad I did. To me it is just that much more of an accurate cartridge with the 230 grain bullets.

Thanks for the info. I am using 89.4gr Retumbo with my 300RUM and a coal of 3.899, how much powder does the 300Norma use and I am assuming the coal is around 3.6? Thanks for any info!

I stared at 86 grains of H50 BMG, Federal 215s, coal is at 3.530, .028 off the lands with Berger 230 OTMs.

This was 208 Hornady Match load development with one grain increments looking for pressure with H1000.

Second photo was the first group at 1100 with 230 OTMs, nothing spectacular, but it was a good starting point for me using H50bmg. This was laying on top of a snow bank with a bipod, wind was @ 12mph @ 90deg. Used 7.5 MILS of elevation at that distance.

Chandlar> "Most excellent shooting dude!"

Swamplord> Yer totally keerect re. the difference between .308/30-06 and the .300 NM. There just is no comparison as to trajectory curve, distance before it goes subsonic or energy delivered at any distance.

In fact 6.5 Creedmoor easily outshoots a .308, that's why it (and .270 Rem.) is used in long range matches so much. Just can't beat the trajectory for that class (mid-weight) of cartridges.

Yes, the .300 Win mag will do quite well with Berger 230 gr. bullets but the .300 Norma mag will do better, because, as Swamplord mentioned, it's a more efficient cartridge case shape. And it has a longer neck to accommodate longer bullets so there is more room for the powder charge.

And finally... General Dynamics has chosen the .300 Norma mag for its new medium machine gun. And BTW, that mg weighs LESS than the current standard weight M240 in 7.62 NATO. The advantage in distance over the 7.62 NATO (.308) is about 1,000 meters! 'Nuf sed.

Fun out in the White Mts. today.
4 shot group at 776 yards.
Wind was from 3oclock at 4-11mph,
300 Norma @ 2796fps with Berger 230 OTM's, 86 grains of H50bmg. Held 4.7 mils of elevation, and into the wind .7 mils.
The mug shot was all I had in my pocket for reference. 3.530 COAL.
25.5 " barrel 1:10 twist

Re: .300 Norma magnum for hunting??

I think the .300 Norma mag will rapidly gain popularity due to its superior trajectory compared with the .300 Win mag. I speak as one who owns both a target and hunting rifle in .300 Win mag.

Plus the cartridge shape helps its accuracy. Anyone questioning this statement only needs to look at the 6 mm and 6.5 mm benchrest cartridge cases to see what I mean.

BTW Jason, great groups!
