Thank you sir! I gave some thought to this Whelen AI. I had some friends do the Quick Load pressure prediction with all my data. Turns out I was wrong and you were right about higher velocity in that it only comes by higher pressure. My loads for the past 21 yrs have been the 53.5/2015 250X2600 (70K) R15/55 310 @2424 (almost 71K) I only used H322 58gr/200X but at 2970fps (no workup for pressure, but I got to be high) an R15/61gr with 250 NP&Seer @2750 (aso oe 70K) Bummer. My primer pockets stayed tight, bolt lift is easy and primers looked fine. IOWs...that Ackley had me fooled, ha. So...I'm having this Mod 700 converted to 358 Norma. I love the velocities and those bullets on game...but not gambling any more. So I apologize for taking exception to your article on the Improved cartridges, ha
