Buddy with the BBT's the nose is not as big in diameter as the drive band. With that .218 mold they'll probably also drop at .220 but if you got the size bushing it'll probably work out good for you.Pure lead is the only way to go with an airgun mold in my opinion, I think that Stephen @ AVS uses nothing but pure lead. Mr. Hollowpoint also uses pure lead as does NSA does but don't mark myword on the NSA slugs because they don't specify if it's pure lead or not
Regulator arrived today and installed this evening. The jury is still out. Gonna' take some more experimenting. I set it to close to max, according to a Youtube video I watched. I filled to 250 bar on the compressor, gun says 240 bar. so, of course I'm getting more shots, but it still starts at lower FPS then climbs, peaks and starts back down. Not tight spread or std. dev. I'll try setting the reg lower, but since it's internal, it's not a snap to do. What I can tell you is, it's a chunk of weight added. So, I now have 10 lb. gun.More to come.
Looks very similar in design to the regulator on the Challenger Pro. I spent a lot of time experimenting with that regulator and had two fail on me (both leaked after 2-3 weeks of daily use). The first one came set to 190 bar (in a .22 cal rifle). Way too much power (the Challenger Pro has a 100 cc plenum). I found that the sweet spot was around 125 bar using 24-28 grain slugs.

Yeah, I was wondering about how much weight it would add.Sounds like a bit too much to lug around for a hunting gun.Hope you get it lined out and shooting like you want.How does the rifle balance in your hand for carrying or shooting offhand now?Hhhmmm right at 10 oz. for the regulator is a bit lighter than I thought it might be actually.
That's good info. How did you determine the pressure setting? Airgun Detective said one turn=100 bar, 1.5=150 bar. Is that what you found to be true? Is it that linear?I set mine at 1.75 turns, but I'm going to try 1.5.
Do the Challengers have any way to adjust the hammer spring tension? How is the hammer spring accessed?
Good to hear you got the regulator working right!What velocity and ft. lbs. did you wind up getting?
25 gr. HN HP slug, 980 fps, 53 fpe. 32.4 gr Seneca Pointed pellet, 928 fps, 62 fpe. Both lost about 50 fps from unregulated, but more than twice the shot count.
