I'd try H4350 and work up to 2900-2950fps. 64-65grains(max) with a Fed 215 should be the ticket.
IMR 4831 also works well with the 180's. 2980fps was possible in my rifle with a max book charge.
Of course work up carefully.
Let us know how it goes please.
Jim, I have been working with the 150 ET/BT combo out of a .300WSM.
Here's my rifles favorite loads(both fairly mild).
Sako 85 (24 3/8" barrel)
.300 WSM
W/W Brass
CCI 250's
150 ET
65.5 grains H4350
2.82" COL
3120 FPS
150 BT
65 grains H4350
2.85" COL
3100 FPS
Using the above loads, both...
Howdy fella's. I went out this morning and shot a few 150 grain E-Tips out of my stock .300WSM. Starting with medium book loads I worked up to Nosler #6 max charges for 150 grain AB/PT's.
These are the only three groups I shot(200 yards).
RL19
69.5 grains
2960fps
2.25"
N550
65.5 grains...
Thanks JD338, the CZ 452 is a great way to let the Sako cool down on these warm days.
A 180 grain bullet at 2925fps isn't the fastest .300WSM in the world but I'm tickled nonetheless.
PS. I don't think a Mulie will know the difference....grin
I might have missed it with the .300 but I nailed it with my little CZ .17 HMR..........grin
At 60 yards BTW.
I am using 65 grains of H4350 along with a Federal 215 GM.

I am getting a much lower ES with the Accubond than I did with the TSX.
JD338, it's a Sako 85 S/S in .300WSM. After having trouble getting consistent results with TSX's I loaded up some 180 Accubonds last night.
.7" at 100 yards during this mornings test. I am a happy camper.
Partition load work up is next.

Thanks for the good answer JD338.
I actually ended up doing pretty much what you described.
I found that with identical COL's (the max my magazine will allow) I can get the Partition .070 closer to lands in my long throated rifle.
How much closer to the lands can one get using a Partition Spitzer vs. Accubond given both bullets(180 grain/.308) are seated to the same COL?
Thanks for any info , Sam
