I've been working on loads for my Sako 75 300 win mag and i shot what i think is a pretty good load. I snuck a peak of my loading bench in there as well, but see what ya think.
 

Looks like you have a lot of room left on the FPS, you're 165's are doing normal 180gr speeds. But, looks pretty accurate and if you don't need more speed, I think you're doin great!

This load is for whitetail so i'm running them a bit slower. I do have room left but this was the sweet spot in .5 increments for this load. I have room to refine it a little more when i get the time but this load is going with me to kill a deer. This is the only hunting rifle i havn't taken a deer with so i'm aiming to fix that.

Go with it. For big game your group is fine. Good luck blooding the Sako.

Ice,

In that case, full steam ahead! Good luck on the hunt, everything should work superbly

Nice group and great shooting!
Now go kill something

Sweet groups and rifle.

A buddy of mine and I have the same identical rifle-bought new in 1997. We use to shoot the factory Winchester Supreme 180gr Partition Golds until 2004 when the Accubonds came out. Since 2005, I reload for mine. Close to 0.4" groups at 100m. RL22 with Federal 215 primers are my loads. Just enough room to pass a sheet of paper between the bullet tip and the inside edge of the clip. No problem cycling rounds.

Another friend in our moose camp picked up a used same rifle 2 years ago and shoots 180gr TSX/TTSX's.

Sako m75ss and Greywolf rifles are what I love!!
I have a few now in different calibers. I recently found a mint m75ss 338WM but since I built my m75 Greywolf 338-06AI I decided against it for now.

I really like the Sako 75's. I actually like them more than the 85. I had another 75 in .270 that i sold to a guy on here. I'm going to rebarrel an AV i have probably to 280 AI or 338-06. Not sure yet but my current favorite rifle to shoot is this one.

I also have a 243 and 22-250 in the m75ss model and had a 300WSM in the Greyolf I sold to a friend last year. I want a 270WSM in a SS model and then replace the stock with a Macmillan. I have two of the 270WSM's in the Tikka T3 LS models (wife took over the first so I bought another for me), but I might sell it so I can get a Greywolf or SS model inthe Sako m75. I also debating on building another wildcat on a Sako m75 "V" action.

Nice, I wouldn 't mind having a 243. Thats still on my list and may be what i buy for my son. I almost bought a Greywolf in 338 federal but didn't pull the trigger. I'm looking at building a 280AI or 338-06 on an AV action i have.

Buying the 243 was the excuse I used before our first child was born...just happened to be a boy. Bought it used in mint condition couple weeks prior to his birth.

I use it as my predator rifle for now, especially if we are out hunting wolves.

I sure do love my 338-06AI I built on am75 Greywolf rifle. A 280I would be another great caliber. Good luck on your build !!
