Tuning a RAW HM1000x (LRT) purchased in 2022

Maybe the .25 barrels are better with slugs? In the .22 the slugs are no where near that. Generally speaking a fatter and shorter slugs are a bit more tolerant to low twist rates of pellet barrel. However key to awesome accuracy especially with slugs is a very efficient tune and thanks to the heavy hammer all the factory RAWs I've seen all have the valve open too long hence how loud they are.

25 cal NSA Slugs 33gr. 100 yards. Haven’t been able to duplicate this results but definitely under an inch at 100 yards.

This rifle is boring accurate 🥱🥱

Is that a custom tune ? If so what do you have your reg. Set at ? How many fps are you shooting those 33 grain NSA slugs at ?
