[QUOTE="Pdvdh, post: 1415129, member: 4191"] I've read that Litz spat-based response to Courtney's work, and others on this Forum. There's been a multiple number of them. Litz and Courtney aren't friends, and that point comes thru loud & clear. Litz needs to grow up, in this regard. I use Courtney's modified Miller formula. Suggest you do also. Of course it's your choice. It mathematically models the answer to 'how much'. Isn't it somewhat intuitive that if the forward end of the bullet is really light (say light as the air in the atmosphere) that the barrel twist rate requirement would be reduced? Lastly, how else could one project 'how much', without spending time and money testing over and over again. I'm going to be testing a 130gr Wildcat bullet in my 25 RUM. Miller formula predicts unstable in 10 twist. Courtney's modified Miller formula predicts stable. I have every expectation they'll be stabilized adequately due to Courtney's work AND because another member has already demonstrated stability in his 10-twist barrel. Stability is determined without consideration of whether or not Litz likes Courtney! Hard to trust Litz when he let's his feelings affect the positions he expresses on external ballistics. I don't tune in to read Litz-authored soap operas. [/QUOTE]
