Same weight--same loads
Not a dumb question, but as long as a bullet is the right diameter,(cal), and the same shape,(pointed boat tail), and the same weight,(165), you can use data from most manuals for the SST. Even better to use Hornady's data. A flat base round nose bullet will have a much longer bearing area than a pointed boat tail. So the pressure required to push it down the barrel will climb higher, quicker that with the boat tailed bullet.
Where you might get into trouble is with the bonded bullets, they tend to be a little harder. BUT if you start out at the recommended starting load for the weight you're using, you WILL be alright.
This advice does NOT pertain to the barnes monolithic solid copper bullets. They're a critter of another name entirely.
