On the pro basic the reg is a real pain to adjust. The reg is putting pressure into a 100cc plenum, while elite is 170cc plenum. Without a reg the velocity can vary on each shot [lookup bell curve shot string] because the hammer spring struggles when the pressure is at 4500 psi and then the...

They're pretty good. I have four molds and some sizing dies and make my own. If I had a thousand rounds of Mr hollow point that would cost around $800. I made 3,000 rounds and still had change left over. I also bought some 9 mm pistol bullets from Missouri bullet company that are not hollow...

I think the elite version is the way to go because the regulator is externally adjustable. I saw a demonstration where the magazines hold larger ammo than the pro because the elite version is much beefier. Terry Fox did a demonstration shooting 10 shots or I think two whole magazines with the...

You're maxed out at about 215 ft lb. I tuned it down to 195 for more consistency. I've tried Hades, polymag, FX hybrid and std pellets. Shot count is another consideration. This is done with 175 bar regulated. The spring is the master control. Just add one or two machine bushings on top of the...

I'm glad to hear that Terry actually has a heart. I had a real bad experience and thought I would never do business with him again but maybe there's hope. A silly little thing but no reply to any email and no answer on the phone calls me to sell the incorrect part on eBay. The invoice was for...

105 grn dish base Griffin super too. The Griffin 130s were actually working well also to my surprise. Only going 805 ft per second won't give you much for expansion but lots of penetration!

I bought one because I saw Mr hollow point testing one from Terry Fox that had an extra spring in the box! I wish I had a spring with one extra coil. I sure wish the regulator was easier to adjust 🤯 I'm able to shoot soda cans at 115 yards with 90 grain hollow points. Setting zero at 75 yards...

I dropped my reg down to 170 bar and added about 14 g to the Hammer. Shooting 125 grain slug size 356 from NSA at 842 ft per second. The pro is capable of 200 ft pounds give or take if you know how to tune it so I got rid of all my pellets and I only shoot slugs now. 90 grain slugs go in the...

That's the one #656637 Lyman mold. So what's your platform? Just that most platforms are under 150 ft lbs. Also I found that slugs may have more contact with the rifling. In testing the 356's go about 8% faster so actually produce more terminal energy. I got 356 and 357 sizers. My Challenger...

remove spring, measure length, inside and out side diameter. number of coils.... examine for damage, put in a vise and compress @ an inch.... that distance can be measured on the travel length seen when opening/closing the bolt. BinTak has springs I'll bet. If you made a jig, you could measure...

The hammer spring is really easy to take out! I must have seen a dozen videos of Ben and Terry changing the springs on YouTube

Aea Challenger reg pressure set low. Added 12 g of weight to the Hammer and the shim of .175. You have 100cc plenum so increasing the duration with more weight and the lift with a shim takes advantage of that plenum for slugs. Before the modification 150 ft lb was all you could get with a Mr...

Well if it's under warranty send it back otherwise take it apart. It's probably not the valve pin but more likely an o-ring. Sometimes you can be lucky with an o-ring kit but some of these o-rings are custom. The machining edge were an o-ring makes sometimes is sharp and I like to take a little...

Probably smack the valve pin too hard. In the last 10 years PCP has had issues breaking the valve because of the material used. Using high pressure and a big heavy hammer and spring put a lot of stress on those parts. That stress is much reduced on a gun that is regulated so your valve is not...

You mentioned the velocity but not the grain weight of energy but that's gotta be loud enough to kill just by the sonic boom! That spread is over 220 fps !! (Grains) Velocity (Feet Per Second) Energy (Foot Pounds) 75 probably 1140 216.38 a bit more with 81 grn 130 Not likely 1140...

Well the magazines have not been a problem on the challengers. Terminators are semi-automatic and they break the magazines all the time. Why anybody would want to waste the air to cycle a round seems counter productive. I think it's just the wow factor and doesn't lend itself to actually hunting...

Lyman Devastator 357. I actually have two of them and it's supposed to be 125 grain but it cast 131 to 133 while the other one casts closer to 127 - 129 grain. There's another model that is closer to 145 grain.

Most semi autos will only shoot one particular kind of ammo and that's typically appellate so in the 35 Cal a jsb 81 grain or the 77 grain Hades. Also as soon as you take air to cycle the nextllllll lol ll round you're losing velocity and wasting air so you're going to reduce your shot count. I...

I really prefer the aea line at the price point you'll get more power and the machine work is very high quality. I also have a hatsan and if I sent you pictures of where I disassembled it and put it back together three times you'll see that the parts are the worst looking like they were made...
