Hatsan .25 Sniper Nitro Piston
Here it is boy’s. Took about 50 shots through it, open sights.
Sat down and rested the rifle on some bags of compressed wood shavings for the final 5 shots at 25 yards. Had 3 pellets almost touching and 2 an inch or so out. Hope it only get’s better with the hawk air max 4×12 and the RWS single piece mount on her. it came with the original spring also. I think they did my 10 for 10 test with the spring in unless they used really light .25 pellets. Because the 10 shot string is
#1- 788.90
#2- 788.18
#3- 793.19
#4- 791.96
#5- 784.81
#6- 796.17
#7- 786.73
#8- 792.47
#9- 714.20
#10- 788.75 That was acctually shots 1 through 11 because # 2 is blacked out on the print out and 9 seems oddly low in comparison to the others.
Wish me luck.

The spring came because Pyramyd air installed the Nitro piston. Guess I’ll have it if the NP ever goes out.
I’ve done alot of reading and post searching on all the Hatsan guns,Walther,webley and a few other that are the same rifles basicly.
They all seem to like jsb 25.4 and preadators and thats exactly what my mrod .25 liked also. not that means anything.
