I ask because I am looking at some heavier copper solids for reloading but don't want to be wedded only to them. Based on the bison ballistics calculator a 8.5 twist would let me stabilize the range of bullets I am likely to use.

Outlier makes 1:8

 
Thanks all. Clearly I am a dummy, but I had no idea temperature and humidity played such a role in whether a bullet was stabilized. I knew they mattered, but going from summer in VA to winter in MT is the difference from stable to either spinning apart or keyholing.

Someone needs to create variable barrel twist tech where you can change the twist rate on the fly.

I make them in 7/8/9/10

We run lots of 8tw for folks that want to do what you're talking about and I've had 300WM and similar sized cases running 175 SMK and 190 SMK in 8tw setups since 2011 or 2012 with excellent success. You would be better suited with an 8 than an 8.5 in many cases. I own an 8.5 that I use for testing only. Happy to discuss with you directly if you want to reach out. Here's contact info at the shop.
