Hello,
Basically, I would like to ask for the opinion of snipers regarding my problem: I have a tuned VSR10 some info of the replica:
0.20 BB; 570 fps; 2.99 J
0.48 BB; 380 fps; 3.23 J
(we have 3,3J /600 Fps with 0.20 bb limit)
Barrel length: 375 mm
Barrel diameter: 6.01
Compression: 3.4 (V cylinder = 36100mm^3 / V pipe = 10600mm^3)
Hop bucking: Maple Leaf MR hop 70°
Hopup arm-nub: Unique, concave as shown in the picture (it pushes the bucking on 2 side edges)
TDC screw adjuster
Original VSR chamber
I use it with a 0.48 BLS BB
With the current config, I can easily hit a terget from 80-85m, (even from further away, by aiming above), my problem is the BB trajectory. The trajectory of the BB is currently (approximately) according to the attached diagram, so I can only estimate the intermediate distances and aim downwards to correct the shot. So now, the problem is that the BB rises after about 20 meters from the place of the shot, and it goes even higher when I add more hop. My goal would be to choose the correct hop bucking and/or BB mass that would allow a flat trajectory at the beginning, a slightly rising and then descending trajectory towards the end, with a long shooting range (picture). What is your thoughts about this, could you recommend a must have hop bucking? Maybe I should try a lighter BB?
Anyway, I've already reviewed scientific, magic-level theories, videos, etc., about the Magnus effect, but this phenomenon is still a big question mark, how can you "manipulate" the backspin to reach a flat trajectory, which rises a little at the end, while the current one is a continuously rising and dropping?
Thanks for the tips in advance!
