In conversation with a fellow team member, we were thinking through the ballistic properties of the minie like a RCBS 575-500 or Lyman 575213 with respect to a solid Lorenz bullet. The math says our bullets are too long generally speaking for our usual twist rates whereas a Lorenz style in 575 should be closer to optimum.
So question is, has anyone experimented with a Lorenz in 575 with standard twist rates and if so, what were the results? The Wilkinson was brought up in our conversation and it does well for some folks. In my 3 band the first 5 shots were just over an inch at 50yds, but fouling caused it to deteriorate quickly. Revisit the same idea of the Wilkinson, but with two large grease/compression grooves. Comments?
