    RTI Prophet / Priest .177 slug shooters - are there any in here? ;-)

    Tested today at 50m Reg at 130 gives me around 1000 FPS for the ZAN 16gr Need to test around that speed some more. Cheers

    RTI Prophet / Priest .177 slug shooters - are there any in here? ;-)

    Thanks, My problem is I live in Europe where NSA’s and griffin’s are not easy to come by. Easiest are JSB and H&N Cheers

    RTI Prophet / Priest .177 slug shooters - are there any in here? ;-)

    Hi all, I think I need some help… I purchased a used RTI P3 177 and added the 600mm barrel and the 2 additional plenum extensions (total 110cc plenum). I was unable so far to get a decent group at 50m even though I tried H&N slugs (13, 16, 20), JSB KO 13.43 and ZAN (13,16,20) I would like to go...

    Hey riazp., What you are saying is the Impact has to be tuned first. I hear you... I've reached the same conclusion. I watched plenty videos on you-tube and have been trying to emulate (accuracy wise) guys like Matt Dubber from AirGunsSA and Ted from Ted's Holdover, but I keep on forgetting...

    Hi riazp, Thank you very much for the info. No need to go out of your way for pictures. I am not a very mechanicaly inclined person to take the gun apart so I rely on my gunsmith for any work done. So far it’s been OK. From what you say it seems you also have the 0.22 caliber. I am also...

    fx impact 177 groups

    Thank you riazp, That is an excellent group. I guess I need to do some more fine tuning. I followed Matt Dubbers advice in his excellent video on how to tune your impact and after getting the reg pressure close to 900 or so only adjusted the power. I will do some fine tuning using the valve...

    fx impact 177 groups

    Hi guys, I just purchased a 0.177 Impact and I do OK (could be better) at 45m (see the 2 inch disk picture below) but when I try at longer ranges like 70m the groups open up too much. The 45m group was shot at an average of 918 fps with the power wheel at MAX (the regulator pressure is around...
