[QUOTE="highdrum, post: 2969520, member: 13732"] So the Berger Calc says you need 1.5sg, but in all honesty you probably won't see anything truly noticeable on paper till you get down to 1.3, a 1.4sg will not have enough difference than 1.5 to see anything on paper at hunting distances. 1k yard benchrest shooters try to keep SG around 1.6-1.8, if these guys knew that over stabilizing was the key to consistently best accuracy at 1k yards they'd be running excessive twist rates, trust me these guys collect more data at 1k yards than any of us hunters ever will. They shoot it on paper and electronic targets. A 10tw is plenty for a 215hyb, unless you're going to be shooting at sea level in freezing temps, at the most I'd run is a 9tw. [/QUOTE]
