Anybody have any favorite 180gr SST loads. I will be shooting out of a 18.5" semi with a 1-10 twist. The closest loads I can find in my manuals are for a 180gr Nosler balistic tip. Same SD but BC is a bit different.

Google found me this:
What powder are you using? -
I will most likely use Varget. The load data seems about the same as the 180 Noslers.Never return fire!
