Hello colleagues, in May I did my first tuning in life, and in addition to cleaning, I put a power plenum, a new combat spring (both from Talon) and pushed a little with Dremel transfer port. As a result, I can now increase the speed / power more than the factory possible.
The rifle is Taipan Veteran long .25, which has a barrel LW 550mm with shock, 17.7 "twist.
I decided to start the tests with JSB KnockOut .251. At 50 m (54.7 yards) at an average speed of 271 m/s (~ 889 fps) and my current setup and opportunities I liked the result. / By the way, I lost 10 m/s (32.8 fps) due to the difference between slugs and pellets, barrel shock /
Then I decided to try the 100m (109.4 yards). At top speed, I didn't like the result. I decided to increase the speed and made it at an average of 281 m/s (~ 922 fps) but I also don't like the result.
/ I apologize for the "decoration" but that's what it is./
Of course there are things that are a fact - on the one hand it is 25 caliber and can not be compared in accuracy with 22 (here some people will not agree for sure but this is my opinion). On the other hand the rifle is a bullpup and tying this to my setup at the moment, as well as the bad from the wind place where I shoot, it's a bit debatable if the result is bad (in my opinion) because of the speed, slugs, barrel, setup, me as a shooter or all together ...
But assuming the problem is speed, what speed would you recommend me to try with these slugs?
Thanks in advance!
PP. Since I ran out of the above slugs, I will now try H&N slugs - in both subcalibers (I took two sets of one of the two subcalibers), and then I have some VK slugs to sample. However, if someone advises me for a specific speed for the upper slugs, it will be useful for other slugs!
