300 Win Mag
 

Guys I just got a new 300 win mag and I wanted to get your guys opinions on loads.

I am thinking of starting with 4831sc. Is this probably the best powder for this cartridge?

RE: 300 Win Mag
 

I have had good results 7828 in 300's I load for.

4831 and RL22 should also work fine.

As far as the best powder that depends on your rifle, bullet, etc. Only way is trial and error.

elkhntr04, im using imr 7828, 215 federal primers, with 180 grain hornady btsp. I have had real good luck with this load.

I have had real good luck with 4831SC in conjunction with the 180 Nosler Accubond and Winchester LR primers. Shot well in several rifles.

Another powder that is often overlooked for the .300 Win Mag is IMR 4350. Although most of the slower powders can make 100 fps or so more speed, this powder can often shoot some really good groups - with some real narrow SD's of velocity. Particularly with lighter bullets - like 150 grains.

I like IMR 4350 and 180 NPs. Best accuracy and velocity for my Ruger 77.

I really thought about 4831sc behind 175 Berger VLD. For closer game maybe the 180 Accubond.

Quite a few folks lately are shooting these Berger VLD's for hunting bullets. The DVD "Beyond Belief" features, I understand, a 168 Berger VLD coming out of a 7MM wildcat similar in performance to a 7 STW. I used this bullet in a 7 Rem Mag this year a killed a cow elk at over 400 yards - bang/flop on a high shoulder shot. Accuracy, as you might expect, is generally as good as it gets with these match quality bullets.

It wasn't a speed load but it is very accurate.
165 Grain Accubond. I shot it over a chrony at about 2810-2830fps

Roskoe,

I am definately going to shoot this rifle as far as I can keep her accurate. That was part of the reason for looking at those bullets. Should do great on mule deer.
