300win mag powder data

[Dev_L]

hello my name is devin not new to hunting or reloading just picked up a savage 110 long range hunter looking in to working up some loads im gonna use 180 elite hunters i currently use h4350for other calibers and i would like to use it , but i am open to other suggestions thanks

H1000,H4831,Ramshot Magnum if you have a lot of H4350 it will work but I prefer something a little slower.

H1000

I loaded for a friend of mine with the exact same gun. I ended up with rl22 and 212 eld-x. Getting somewhere around 2825 fps. I'm not a fan of that powder but it did quite well in his rifle

H 4831 and R 22 have been the go to powders for 180 gr in a 300 WM. I use to shoot 180 BT's at 3080 FPS with R 22. 4350 will work good too but you won't get top velocity if that matters

I've been doing some load work up for my 300 Win Mag 24" Bergara.Have you looked at the ballistics of the 200gr Accubond that those speeds?It's quite impressive.
168gr Nosler BT
74.0grs Accurate 4350-3134fps

180gr Nosler BT
72.0grs Accurate 4350-3071fps
74.0grs Ramshot Hunter-3130fps

200gr Nosler Accubond
71.0grs of Ramshot Hunter-2981fps
82.0grs of Ramshot Magnum-2994fps

I've had good luck loading 300WM 180 gr with H1000, RL22, IMR7828 and H4831SC. If you made me choose only one, it would be H1000.

I loaded 165 accubonds and 190 accubond long range bullets. H 4831sc was great with the 165's and n565 and rl26 were good with the 190's. I couldn't get enough h1000 in the case before it was too compressed to give me pressure signs with the 190's. I had great velocity with the combos above and good accuracy at close to max loads.

Helped a friend load 180 NBT's in his Winny. I don't own one and went in assuming it'd be 7828/Re-22/H1000. His best accuracy & velocity? IMR4350

A repeat of something I've seen over years of reloading rifles, i.e., when you're not seeing the accuracy or velocity you want, sometimes stepping down to a faster burning powder unlocks the solution.

 

[baldhunter]

I've had very good luck with 72.0grs of either Accurate or IMR-4350 with 180gr bullets and 74.0grs of the same powders with 165-168gr bullets.That's what's great about the 30 cal,a bore that size can burn many different powders on the burn rate scale and the volume of the Win Mag case gives you the space for even the slow burning powders.I shot this group at 200yds with a 180gr Sierra BT and 71.0grs of IMR-4350

IF you can find RL26 pixie dust you will be impressed with its performance with 180+ weight bullets. G1 Sendero 300WM 26" = 3250 with 180 gr Sierra Gamechanger, 3150 with Speer 190 Impact. Both shot well and may replace the 200AB with 72.5 RL22 = 2950. Not sure yet since the 200AB shoots so well downrange that its hard to replace when you have so much confidence in it. Personally, I don't think the 300WM really shines until 190+ weighted bullets. Anything I hit with the 200AB is anchored from whitetails to elk so its a good all around bullet for me.

Having said the above, IMR 4831, IMR 4350, IMR 7828SSC all have shot well in my 300WM.

Another powder to try is Reloader-17.It gives some high velocities without pressure signs.In a way it kind of scares me because it's kind hard to know when to stop.I load it like IMR-4350.It was a new powder when I tried it around 2009.This is what I got with 180gr bullets.I shot three and moved my scope down and shot two more
71.0grs-3110fps
72.0grs-3175fps
72.5grs-3215fps

Rl-17 worked well in my 300 wm long range Hunter .
