Well,
Here am I, back from my tests. I finally received some JSB Monster redesigned. I shot the first pellet down range and it went directly to the aimpoint. The next four pellets just followed the same way. Five groups of five in an 1/2 inch at 60 meters (the small target is 1 inch). Just fine, exactly what you expect from that kind of gun.
View attachment 27990 I thought something might have changed (I disassembled, cleaned, checked, reassembled....). So I switched back to low power and took some JSB Jumbo Heavy (18gr). The first pellet hit the target below mine, the second went into a target in the above row. Just awful! Totally unusable. 5 shots - more than 4 inches at the same distance.
So here is my question: Are those poor results with the 18gr common to all those guns? Do I specially have a barrel that is extremely picky with pellets?
Although this gun is a pleasure to shoot and extremely accurate with the monster redesigned, I have the feeling that I lost the promised versatility: the idea of switching power and pellets according to the needs.
It still is a woonderful gun and almost a piece of art, however I'm still wondering whether I should keep it or send it back. I'm fully satisfied with the results with the redesigned monsters but at the same time, a little disappointed that I can't use anything else. When you watch AOA's review of the gun, they achieve good results with different kind of pellets.
It's totally understandable and normal that the barrel has its favourite pellet but it my case, the others are not just a little less accurate, they're just impossible to use properly.
Food for thought....
