Hi. Has anyone here ever tuned .22 blizzard for more power.Or have their gun tuned? I bought some 30gr Prometheus Piledrivers andwas thinking of trying to get more power out of my gun. It shoots now 26gr Skenco Big Boys for 955fps = 53fpe.Would i be able to shoot 30gr Piledrivers for about 1000fps that would make about 70 fpe?
Hi. I tested the 30gr Piledrivers and here are results. First string, 10 shots with about 5 grams of extra weight in hammer, hammer spring at max and starting pressure about 220bar: 921,934,956,947,947,938,938,927,918 and 917fps. Ending pressure 180bar. Second string, 10 shots, no extra weight, hammer spring at max and starting pressure about 205 bar: 936,930,938,937,941,931,927,918,918 and 912fps. ending pressure 170bar. I tested velocities with Combro Mk4 chrony but don't fully trust its readings. I will test this later with my Shooting Chrony. So not 1000fps but maybe later...
