Hello friends.
I just bought one tin of Jsb Monsters, one tin of Monster redesigned and a tin of. 177 Jsb Hades.
I decided to test them at 51m which is 55y.
Each pellet was tested with 2 targets to see if there is any consistency.I turned the hammer spring to max power and then i just back it out 1 turn.At that tune monsters were going around 810 and monster redesigned at around 790.
After testing heavier pellets i backed out hammer spring to my older tune for Jsb heavies 10.34 gr.At that tune i tested first Hades pellets and then heavies.
You can see that in my rifle the best pellet is Jsb exact heavy all the others gave bad results.the best group is 4 pellets in 1/4" and one a little of but still 1/2".The other group with 10.34 grainers was shoot in little worse conditions because wind starded blowing more but still four of five pellets under 1/2".
I also shoot one group with heavy jsb's on higher power tune and they were fast about 925 fps.I saw one pellet spiraling at that speed and also the group was not great around 1,5".I didn't take a foto of that target. Those pellets in this rifle likes to be under 900fps.
Maybe if i could push monsters faster i would get better results with them.
For now best pellet remains Jsb exact heavy at 870 fps.
Regards Marko
