I bought a 300 WSM
shortly after they were offered for sale, so I do have a little experience with the round.
My first 300 WSM was a Winchester Model 70 Coyote and I still own that gun and it shoots great, but my first few shots with it were not so satisfying. I think that Joe King is correct when he says that the factory loads are very hot. I shot some 150 grains Winchester Silver Tips out of my gun and they were much too hot, 3300 + ft/sec.. If my memory serves me correctly the factory recalled some of those loads. The bolt lift was heavy and the primer pockets were stretched. So yes 3300 is way too hot for a 165 grain bullet, so something is going on for you to get that number.
The factory load could just be loaded too hot for your gun! Federal brass is known for being soft so with too hot a load and soft brass you get what you are experiencing.
I have been shooting the 300 WSM for 10 years or more, and have never experience a blown primer or a heavy bolt lift since. The only other time I have seen too high velocity for the load and gun was when a friend bought a brand new Remington 700 in 243 Win and shot it across my chronograph and it was way too hot. We found that he had not cleaned the grease out of the barrel and this produced the hot load. After the barrel was cleaned every thing was fine.
I now load most all my 300 WSM loads with Norma brass. It is heaver than Win, and Fed brass so the volume of the brass is a few grains less, this means that you need to start low and work up. I have brass that I have loaded more than 10 times.
