I'm interested in your opinions on the sweetest factory load for a combination of target shooting and mule deer. The rifle in question is a heavy barrelled Sako AII and no doubt there is a sweet bullet for the .308, like the 165 grain is for 30.06.
Thank you

You my friend are asking an impossible to answer question.
There will be naysayers but like it or not, every rifle is an entity unto itself.
Cartridges will change with every new batch. The bullet might stay the same as will the case dimensions but the powder/primer combination can and will change from batch to batch.
The best advice anyone here can honestly give you, is to try a couple of different brands cartridges, then if you find one that shoots really well, go back and see if they have several more from the same lot.
Other than that, if you're planning on shooting more than half a dozen boxes/20 per year, look for a used reloading outfit or even a LEE entry level kit for under $150, find a load that your rifle likes and stick to it.
Another piece of good advice is to get a really good cleaning set up. Not a BoreSnake.
When your groups start to open up, they usually do after 30-40 rounds, clean the bore of carbon and copper fouling. Take a couple of fouling shots and you're good to go again.
Never go hunting with a freshly cleaned bore. You just can't normally predict where the first couple of shots will go. Most rifles settle right down after a couple of foulers down the tube.
There is a lot more but that should get you started.
