Well, I'd rather not have the pellet make a supersonic crack, so less than ~1100fps. Reading posts of successful long distance shooters seems to favor speeds up to 900 fps for pellets, maybe more for slugs or longer pellets. But I have yet to test accuracy. Tomorrow!
seems like you could possibly still get enough shots and heavier slugs and still be in the subsonic zone.. it's nice also to not have to wear earplugs if you don't have the crack .. the heaviest I have shot are still just pellets but they are the heavy redesigned jsb and hit pretty hard.. but I have heard that slugs are more accurate, especially boat tail slugs.. I also have read that slugs don't shoot well in some guns because of the extra drag.. seems like a slug could be made with ridges or bands around it so just the bands engage the rifling and seal the air and not the full length contact.. been interested in swaging slugs so you could have whatever weight and shape you want.. and totally consistent.. and they have groovers.. but it's very costly to get set up..
I have the ring lock kit with the different sized orifices. I didn't mess around with the different sizes too much. Which slugs have you been experimenting with? I assume you're using the factory barrel.Have you tried reducing the valve orifice? They have their Ring-loc kit, and other aftermarket suppliers have theirs, like Talontunes. The idea is with a smaller orifice, one can shoot at a little lower velocity more efficiently, and for a .22 slug in that gun that might be subsonic but still fast, use less air and have a broader shot curve. Not regulated but more usable shots per fill.
I tried this today with my Condor, coincidentally, and with Airforce's 0.123 orifice had a .22 20gr slug flying at 905fps with the power wheel at 6, and 973 with the wheel at 12. I estimate that orifice will give me close to 100 useable shots per fill, although I may have to dial the wheel a little through the shot curve.The AirForce Ring Loc Kit: Part 3 | Blog | Pyramyd AIR

Ah, that answer gets interesting. I have a NOE "boat tail" slug mold 217-30-FN-BJ5, but I cast tin pellets so they weigh only 20 grains. The slug has a front ridge and rear band that engages rifling, but otherwise doesn't drag on the lands. Barrel is 24" stock. They shoot, and well enough at 25 meters, and I'm hoping to test them at 50 meters tomorrow.
I've never casted anything other than babbit bearings.. and it was years ago and I was just the helper for the old timer who was supervisor.. you can really learn a lot from those who have been there done that..
also I have a old white gas blowtorch in good working shape from my grandfather and I think I remember seeing a ladel in a box, also from my grandfather.. also do you have to use flux? or anything else?. thank youI've never casted anything other than babbit bearings.. and it was years ago and I was just the helper for the old timer who was supervisor.. you can really learn a lot from those who have been there done that..
so I really like the sound of you mold.. does it take a lot of time to cast them? where might I find the mold and materials for casting.. seems like when I did the babbit bearings he brought a old white gas blowtorch and it had a bracket for holding the ladel that we melted the metal in..
please let me know if you can tell me more about it.. pm message would be great

Mark, sorry I missed your post. Casting tin seems similar to lead but at a lower temperature (~500F).
if you want help cutting it off and doing a good recrown I can easily do the barrel for you on the lathe.. I finish the inside taper with the barrel spinning fast and a die grinder with a tiny stone at a 45° angle.. my notos shoots a lot better..
nice thanks for the information.. wish my grandmother was still around, I don't know if he poured any bullets but I still also have his 10 cavity aluminum fishing weight mould..
I guess what I'm interested in is doing shooting like the Quigly bucket challenge.. it's awesome to see those guys shooting, I think all of them are using airforce texan 45 caliber, although I read that the most accurate for long distance is 308.. it's amazing to see them shoot over 1000 yards and they have to have a scope jack just to get the target in the scope..
My buddy still has my Jet 13x40 lathe...I have a PTG 11 degree crown cutter but only have 224 bushings... Ill probably just crown it old fashioned using tooling settings angle....I don't have a mill though.... A major setback with airgun s.. I'm glad to know you have tools for air smithing
. Hopefully in the near future do a long TJ barrel maybe.224. 14 twist....NOE makes a real.nice 51 gain .224 slug with B.C over .2... For the Airforce Talon...Ordered 300 bar valve and 90 gram hammer and heavier spring. Probably run 3600 psi tethered.... For know excited to test short barrel and 28 grain slugs.... .. I try to share my .510 powder.coat slugs on the forums,, not to many 510 users here lol... If wasn't for the help here I would never be able to enjoy or afford the sport...
