Favorite 300 wsm loads

243win · Mar 11, 2019

I just purchased a savage 110 in 300 wsm that I'm really looking forward to start reloading for and I'd like to hear what loads you guys are using in your 300 wsm's. I have some 180 grain accubonds that I plan on starting with, and I also have 8 pounds of 7828 that I hope will work in this rifle.

IMR 7828 ssc is a great powder, you have a great chance to get a good load with it. I had great success in the 300 WSM I had with H 4831 sc and 180's and RL 15 with 165's. It can handle a wide variety of burn rates and there are few bad choices out there.

My Tikka likes RL19 WITH 180 AccuBond ....

My Savage really likes RL26 and 180BT / AB, the Sako 85 does also. RL17 isn't too bad.

I have used H4350 with 180s in the past. RL-19 with 165s and currently RL-19 with 200s. You have plenty of good powder options with the WSM and shouldn’t have a problem finding a load with 7828.

Sorry, double post.

I'm using 69.5 gr of WXR with a WLRM primer in Winchester cases for 2978 fps in a 23 1/2" barrel for 0.4' groups at 100 yards.
70 gr of V N165 gives 0.8" groups. Sorry, I didn't chrony this load.

I shoot the same loads out of a Thompson center venture. Most accurate load I have found.

The 180 gr AccuBond that the OP is looking for data on.

I've been using 64 grains of RL17 with a Sierra 180 Grain Gameking for 3030FPS and groups of 3/4 inch at 100 yards. Dropped my last Elk with this load.

The NBT 165 gr with 66,8 gr N 160 worked quite well with a Sako out to 600y in Africa.

Anyone that has a load using Norma powder? For bullet weights 165/168 up to 180gn.

Thanks

Yeah, me!
MRP with 165 gr Balistic Tip.
Have to be near my computer to tell you how much...

Since your iPhone speaks Swedish, I assume metric units are ok (or a mix):
73.0 gr MRP
OAL 72.64 mm
165 gr Nosler BT
4400 bar (absolute max, start way lower!)
964 m/s
Barrel 65 cm
Federal large rifle mag match primer
Norma or Lapua brass, not sure.

Works well from a Sako, though the current load is N160

But really start low - I have the impression that my lot is rather slow.
