Will knowing your twist rate help you decide on a bullet weight. For instance I measured the twist rate in my Winchester model 70 300wby mag with a 25" barrel. (Measured from action to crown). It came out to 1 in 10. Would this barrel favor a heavier, higher BC bullet like a 210gr over say a 185gr or does it not matter. I'm starting some load developement and am trying to take everything in to account since stuff is hard to come by right now.
