Re: What Rifle Reloading Did You Do Today?

I'm not really one to question how others arrive at high velocity cast bullet data , I shoot some pretty spirited loads often matching jacketed loads .
Did you perhaps have a typo in matching load levels with a 180 gr cast bullet and a 168 gr jacketed .
I erred once in a 6.8SPCII data log in that my 27-130 was infact 141 gr and I should have had some fudge factor as it was chambered in a 7mm barrel making it a 7×6.8 SPC . I was 1.5 gr down from the 130 gr jacket max with groups closing and velocities tracking . Then I had action spray and a .250 dia primer pocket with no primer or anvil to be found . Best guess is someplace around 75-80kpsi in a 62kpsi max cartridge .
