300 SAUM Loads

[Wayne50]

I have a 300 SAUM w a Bartlein barrel in an Alaskan Tutanium. Not really found anything that shoots great. Are there any recommendations. Kinda favor Barnes bullets.

 

[Trm82]

I'd try 168 ttsx
I've never had them not shoot.
RL 23 or 17 would good powders.

Kinda favor Barnes bullets.

This may be true but your barrel may not favor these bullets. One of life's great mysteries.

There is really no good information to help make decisions with.

One significant helpful fact would be your twist rate in the Bartlein?

Second would be the overall length of the cartridge and how far you're seated off the lands.

My Remington 700 BDL SS shoots 130 Barnes TTSX very well pushed by Ramshot Big Game.

I've got 4 300 saums they all will shoot 165 or 168 Barnes with IMR 4831 all are under .5 groups at 100 yards!

yep IMR 4831sc works like a champ in both the 300 and 7mm SAUM generally run 165 in my Mdl 7 300saum. rifle is a .65 shooter

My go-to load for custom match Rem M700 .300 RSAUM was 190gr. Sierra Mk, H4831SC {63.0grs} 9 1/2 Remington primer gave me 2945 fpe with crazy SDs of 8 fps this was a load I used in Raton NM and many other LR matches over the years. The Berger 30 Cal 190gr hunting (VLD) works great, I would think the
The Barnes Long-Range X Bullet (LRX) 190gr would be a great hunting bullet for the lead-free folks, just back down on the powder and start up slow.
Good luck... Cheers

Are you using a short action?

No, it's a long action.

 

[Retired2021]

I have a 300 SAUM in the Remington 7 short action. Because the mag is short, any loads that shot well had to be hand fed. I had a fantastic load with Nosler 180 BT at 0.020 off the lands, but to mag limited to 0.080. I switched to the Hammer 165 PH and have been very happy.
24" barrel
CCI BR2
Varget @ 55.1
Hammer 165 PH set at COL 2.800
Velocity 3007 (according to QL pressure is 63.4K so start work up with a lower charge).

Everything I have shot (two mule deer, one elk) with this load did not take a step.

 

[NZTahr]

168 Nosler BT and R17 or N550. Easy 3K with 20" barrel.
Also 150 Barnes or Fed Fusion with N550 or Varget.
