I too have given up on the SST's...only use 2 Hornady bullets anymore (a round-nose 170g for my 30-30 and a 80g FMJ in a 243...which I think they stopped making recently).

I have found much better accuracy and performance on game with Nosler bullets...especially Accubonds in my mags (ballistic tips and partitions in others).

There is also a lot of truth to what homers brother states...velocity is key to bullet performance...and faster isn't always better (I know...Mr. Weatherby is scowling at me right now)...every rifle is different, most mine perform best accuracy wise well below maximum load potential...with a few exceptions. Spend the time trying different powder and bullet weight and brand...it makes a difference. I don't own an '06...so can't help ya there on specifics. My brothers '06's both love 180g bullets...both the Nosler Partition and the Barnes X bullets, not sure which powder he is using, but I believe he is using IMR-4895 or H4831sc.
