My slug is 5.52mm with micrometer reference 5.516.mm
The NSA slug is 5.48mm
hallo vadimas
are the 29 grain slugs not too heavy then? for the 500mm loop at what speed do you shoot?
This is an upside down world
Last 10 24gn, 1 to test speed 850fps, 1 to aim, and 8 went like this in 44yds with the pellet liner
Crank the reg to 140, last 10 22.5 gn in 84 yards now, no fine tune, pellet liner, 950 fps and
Worst moment ever to went out of stock!
To be continued...
Vermin Knocker from d-rig, Dale, is what I am using right now, be sure your pellet liner is 1:19
Check him on ebay 22.5 and 24gn
Sadly this weekend I did not have much time to test
I crank the reg at 155, put a JSB monster to check speed, shoot it a couple of times and (600mm barrel)
So It can easy go over 1000fps with the new ValveTube and a 700mm barrel
Anyway, shoot a couple of rounds before the light went out @50m 55y from 22.5 gr to 30gn and it looks pretty good, on 24gn there are 2 groups, no need to measure, each hole measure 0.22
