Thanks, convinced it is bullet design since it is not close with any gun I have and completely inconsistent with other data. Agree on the pressure, which was pretty much why I posed the initial question. Historically I have stayed with pretty normal bullet designs. As I'm venturing into other bulk opportunities it seems that there are very non-traditional bullet designs (deep hollow bases that change the "normal" contact surface length, teamed with conical bullets that now must extend the ogive so they hit the rifling, non-standard bullets weights because of this, etc.).e careful with 9’s, 9mm loaded .010 to deep can double the working pressure of some loads due to the compression of powder. Your issue may be more to do with your weapon and the bullet design. Beware!
Unlike the big manufactures (Sierra, Speer, Hornady, etc.), they don't provide load data and in many cases no COAL info...since they don't have data. For plated bullets, one advises to use data for jacketed or lead bullets. Well these are different...which is it??? These companies wouldn't still be in business and selling lots of bullets if many others didn't find a way to make them work. For me, they are out of my comfort zone, especially knowing my family shoots my reloads. It's not a surprise that with some companies the "normal" bullets are sold out and these non-standard ones are still in stock. Thing they call that a clue
Thanks for your input!
