[QUOTE="Rijoh, post: 2474851, member: 109385"] Not 100% on the model 7 but I believe the factory twist is 9.25. The higher the elevation the less it will matter. There are lots of twist calculators out there you can verify stability with. I agree you should be in the 140-168 grain range. 175+ will start to be marginal.
