Hello Steve,
i love all your videos! I’m learning a lot by you, it’s not easy for me because I living in Belgium and I’m a french speaking so I try to understand all you say and the subtitle help me too.
I’m new in the world of airgun and there a lot of things to know for understand how it’s work and be able to tweak power, weight pellet, etc..
in this video you speak about the speed of pellet in general, i have read and see lot of videos about that and all go in your way.
but today I make some tests with my airgun and the result is a bit strange..
i have shoots 5 pellets of 3 differents weight at 50meters and catch the speed with a Chinese chronograph.
i shoots with a umarex reign .22 fac version (but poor power result.. +/-50joules and the specification give 60joules) connected to a scuba tanks and a huma air inline regulator setup to 150bar because the internal regulator is not as good as it was expected.
I had made a speed test of the internal regulator of the reign before from 230 to 100bar and I have the best power at 150bar.
(up to down on the picture)
1 Jsb exact 1,030
speed result 315-315-311-310-312 and a nice group at this range (I’m not a great shooter yet)
2 Jsb exact 1,175
speed result 297-299-297-298-298 and a just a group... lol
3 H&N barracuda match 1,37
speed result 282-285-283-283-283 and really not beautiful group.
so in my case, the pellet with the higher speed give me the best group. How do you explained that ?
i have also try the Jsb monster redesign 25gr another day the speed was 255m/s and the result between jsb 1,175 et the H&N
Thanks you for sharing your knowledge !
Jerome
