I anneal the 168’s for my SAUM, and have found they performed well. I understood they should open up better at longer ranges/lower impact velocity after annealing being softer?
As a side note, I load them to mag fit in the model 7, so the jump must be quite big, and they shoot into 1/2”, both when it had a 22” and now a 17 1/2” barrel. 180’s in my practical also have a 60thou jump and are very accurate, so maybe try a big jump and see what happens?
Cheers
