I take it that the S&B primers were Sellier & Bellot small rifle primers. Seems like they worked just fine. Any issues with these?
My 6.5X47, a Ruger M77 MKII, has a firing pin hole in the bolt face that measures .072 and the hole/pin fit is very snug. When using the same size bolt face firing pin hole in a .17 Rem, (slightly below max and no problems with CCI 450's) regular Winchester small rifle primer cups were extruded into the hole blocking the firing pin. Pressures for the 6.5X47 L are greater than those of the .17 Rem. This resulted in me only using magnum type primers having thicker cups in my 6.5X47 L. Looking at the Sellier & Bellot catalog I see their small rifle primers, V360589, are intended for the .223.
This is of interest to me; I can get really good deals on Sellier & Bellot primers but have held back being uncertain of suitability for a cartridge like the 6.5X47 L with its high pressures approaching 65 K psi.
Possibly, your fine BAT bolt face has a smaller firing pin hole than my Ruger M77 MKII that was intended for .243W & .308 rounds (LRP).
Thank you for posting your incredibly fine results with accompanying data !
