As some of you surely know, there is no external hammerspring adjustment on the Classic and its trial and error. I want to get mine to an intermediate setting and wondering if there is a fixed number of revolutions between all the way out and all the way in without over stressing the spring. Then I cold back out a certain number of turns as a starting point. Bought the gun with reg at 125+ bar and shooting 18.1’s at 910- 920 fps. Want to get it to 860- 880 by turning reg to 1110- 115 and HS adjustment. Appreaciate any insights.
