[QUOTE="rustyshackleford, post: 2216308, member: 59526"] Just shoot them both and see if the gun prefers one or the other. May make the quandary real simple real quick. If they both shoot great work up a max load with one and you can estimate the velocity with the other using the formula in the attached image. From there plug in the Litz G7 values or go to hornady’s page and use the G7 from the BC page. Hornady tells you on that page they use inflated numbers for marketing on their packaging so use the ones on the BC page. That’ll tell you what you want to know. Using RL-15 I got a 195 TMK up to 2550 from a 20 inch barrel so I think you’ll get plenty out of a 20 with those bullets [/QUOTE]
