I'm working on Mountain Molds design page. I just built a Browning Model 71 in .50 Alaskan. My immediate question is the nose profile design of a 525 gr. Linotype bullet. I'm looking at "plain secant" vs. "bore riding secant" with a 75% flat on the nose. Are there opinions/preferences on these two nose profiles? I can also entertain other profiles if more experienced folks will comment.
