I would like to have the time , money, spent over the perfect load and with the reloading situation now, more so.
But I did have fun along the way! Happy shooting! 1" groups for hunting is good.
What COL are you using?
My most accurate 308 loads have been with 3031. And it doesn’t meter as bad as it used to.
Instead of changing powders, can you determine the comparable jump to lands distance and try that first? Do you have a chrono and can verify your velocity is comparable? I regularly switch BT for AB and those seem to be close enough. Good luck.
The good news is that 308 is one of those cartridges that seems to shoot well with a lot of different powders. IMR4064 is known to be one of the good ones and a lot of target shooters claim the most accurate. The only real downside is that compared to some newer powders it is more sensitive to temperature swings. In cold weather (20's or colder) it will be noticeably slower than when fired at temps in the 70's and you could see an overpressure load if shooting in triple digit temps with a load developed in the 70's. But unless you shoot in extreme temps it does fine.
Reloader 15 is another good powder that I've used. You may just need to tweak that load some. Varget is my go-to 308 powder if you can find it. Another good one is IMR4166 as is Ramshot TAC. There are others, but those I have used. With component shortages we have to use what we can find.
Welcome to the forum btw.
I was fortunate that years ago I tried several bullets and loads for everything I owned to see what worked best. Now looking at my logs saves me from having to do complete workups and what supplies to buy when I see them.
