Ultrastu Posted February 16, 2020 Report Share Posted February 16, 2020 They are very heavy and are gonna be air hungry. Personally im gonna wait till the hybrids come out .at 26 grns they shouldn't need too much more push than a jsb king . What you putting them through ? Slug liner .?

figgy Posted February 16, 2020 Report Share Posted February 16, 2020 I watched some slug testing today on YouTube. In .22 h&n the Daystate regal preferred the 20.2 gr. Maybe the pellets barrels don't like the heavier slugs. Some lads on the AGF have received they're batches of slugs for testing. How many are in each weight? Could take a fair few to find the speed they shoot best at. Interesting times, let us know how they work out. Quote Link to comment Share on other sites More sharing options...

villaman Posted February 19, 2020 Author Report Share Posted February 19, 2020 33 gr @ 940 FPS on 135 bar setting 3 on power wheel and like I expected very , very accurate . At 75 yards just under 1 mill dot but group under 5 pence size and a zero on 45 yards need to try the others and 33gr at longer ranges 100 - 150 yards Quote Link to comment Share on other sites More sharing options...

I heard all sorts of scare stories about diy tuning. Quote Link to comment Share on other sites More sharing options...
Chaz25 Posted February 20, 2020 Report Share Posted February 20, 2020 I've used the 33gr's in the stealth, mine being a sub 12, you would think it pointless but over 10-15m they still carry good energy. Quote Link to comment Share on other sites More sharing options...

Impact is designed to be tuned not only that , I had a heavy hammer weight and spring guide made and a external plenum kit most important thing to do is write your settings down from new Quote Link to comment Share on other sites More sharing options...

figgy Posted February 21, 2020 Report Share Posted February 21, 2020 (edited) Lampwick watch 68whiskey on YouTube he is tuning a impact with power plenum for his friend and take you through the steps. Ernest Rowe videos are also good to watch. Using vernier calipers, measure the gap on valve adjuster, then measure the gap on hammer spring block with set on max. Write them down with reg pressure and peer wheel setting max number or letter you use. With fpe speed and pellet you use that tune for.
