.300 Win Mag powder

[troyspinetar]

I loaded up some batches of 180 grn Speer HC using H4831sc. They faired well for a basic all around hunting load for me.
I picked up a can of H1000, curious if anyone has any input on what differences it offers...if any?
I will probably play around with some and see. Planning to use the same 180 grn Speers.

I have no input with h-1000. Always use H-4831. My load comes from Sierra manual 2nd edition. 78 grains for more than 3100 fps. With 180 PT,s or AB,s it does deliver outstanding velocity and accuracy. I do know there are guys that use H-1000 and like it. This target is with 77 grs.

The .300 Win Mag is a real performer through a wide range of powders and is one of the most forgiving cartridges I have owned when it comes to seating depth. I have shot allot of .300 Win Mag through many factory and custom rifles in the chambering over the years and my go to powder for speed and accuracy has been RL-22. For years I shot a bunch of the 180 BT's , super accurate bullet from the .300. One year it accounted for my best Rockchuck season. 176 of them in a single spring & summer. Lately I have Prefered a little speed over weight, I've been shooting the 165gr BT's on top of RL-22. For big game I just switch the 165 BT for a 165 Accubond and I'm good to go with the same powder charge.


My factory .300 Win Mag Sendero, bone stock. Not even a trigger job slings the 190 Sierra MK's fairly well over RL-22.



This was shot at 400 yards one day when I was confirming my real would drop at 400 yards with a 300 yard zero. Slight right to left breeze, I didn't dial or hold for wind. This was with the same factory Sendero, the real world drop matched of ballistic App perfectly. I just slapped the orange dots on a box backed the truck off 400 yards and shot from the prone, using my range finder as a rear bag. The one shot that's out felt solid when the trigger broke but who knows?

I've had great results in both of my .300 win mags with IMR4350.

I used H1000 in the 300 WSM when running 200gr bullets and was pretty happy with the results. It may be a little slow for the 180s, but try starting around 72.0 grains and work up. Hornady lists loads from 67.0gr up to 78.0 for their 190 BTSP.

H4831SC is hard to beat in the 300 mags.

H4831 and IMR4350 have been my choices for many years.

H1000...it's what the "good guys" use in 300 Mag!!!
