The 10mm wasn't on my radar in 1993. I think there was the Bren 10 and Colt Delta Elite back then and they were beyond my budget. Neither one interested me then or now. I was looking at velocity mostly, not Ft/pounds. I zeroed in on the 155gr in the .40 at first for the over 1200fps Blue Dot load which was close to the 158gr .357 loads of the day. Now I shoot 165, 170 and 180gr loads, some hot, some not.
