Hi, so i have a hatsan flash .177 that i would like to get some more shots out of, if possible, without the need to machine anything cause i don't have any tools for it and i am useless with them anyway. What i have done is to remove the 2 spacers that where in front of the hammerspring, and put a weaker valve spring in it, I read somewhere or saw some video of someone doing that to get a better curve, i don't know how many turns i have on the hammerspring and have not typed down every shot on the string, but my numbers are as follow in - 3c:
Jsb 10.34gr
Start: 190 bar
245 m/s (803,8 fps
10 shots 160 bar 246 m/s
20 shots 150 bar 254 m/s
30 shots 130+ bar 244 m/s
40 shots 110 bar 248 m/s
50 shots 100 bar 249 m/s
60 shots right under 100 bar 244
72 shots noticed last 2 shots going a little lower @ 35m 80 bar 232 m/s, so the speed was probably around 244 m/s for shot number 70. So i get 70 shots within 10 m/s spread, 244—254 m/s, 800,5 -833,3 fps, 30 fps spread, is that ok? Looking @ the start the gun uses 30 bar for 10 shots 190-160 bar, could i turn the hammerspring to improve that without getting bigger spread in speed, or should i just fill to 160 bar and use 60 shots between 160-80 bar?
Thank you and Merry Christmas!
