Final TalonP Modified with Chrony Results 70+ FPE
:hoot:
Here’s the bare gun…27″ modified, with a 12mm 16″ LW barrel that fits perfectly inside the OEM frame, Tagdagger MicroLite bullpup/carbine kit, a Maddog Doug stock, and a 1lb two-stage “Super Sear”. Also an after-market trigger for my chubby fingers. With a 16″ barrel, you still have enough free shroud on the end to use a slide-in/grub screw LDC. And…no, I don’t miss, or need, the choked barrel tip! Accuracy was unaffected.
It’s amazing what an extra 4″ of barrel will do. The 12″ OEM TalonP can produce 50 fpe from the factory. It’s capable of much more.
A 36″ TalonP (with 9″ LDC) producing .30 caliber results, and still quiet enough to shoot off my back deck, will handle anything sneaking along my lakeside shoreline!
Weight is 6 lbs, however, the weight is so evenly distributed with the MicroLite and Maddog mods…it feels like a 5 lb gun!
It pushes 31gr pellets at 980 fps (66 fpe). It’s peak power curve is achieved between 2200 to 1500 psi. The key to max power is the correct top hat setting (in the low .90’s), heavy Condor hammer, 7 gram extra weight on the top hat striker, and attention to the power wheel setting. (Hint…mine is set on “0”) Of course, your milage will vary! You need a chrony, and a lot of patience, to find the right balance. But once it’s dialed in…all you need to know is the max psi to fill to, and what power wheel setting to use for the weight of the projectile being used. Not as simple as a regulated gun…just more fun!
Here are some initial chrony settings:

I have to say a big THANK YOU to you, Hoot! I checked my tophat clearance and it was .140″. I brought it down to .093″ and now things are seeming much better. I really appreciate you taking the time to share all of the info that you have. Your single post, above is loaded with useful stuff. I’ll let you know how it goes. I have an 18″ .25 barrel in the gun, now. I haven’t cut the choke off of it, yet. It’s snowing hard right now, but I’m going out to shoot anyway.
:hoot:
Agreed coors!
On all “shots of opportunity”, those without a definite backstop, I experienced 75% to 90% ricochet and they were really “singing” when they took off in another direction. Whether it was the rocky ground we have, or a hardwood tree, the solid lead slugs did not want to stop where they hit…too much remaining energy upon impact tended to distort the projectile and re-direct the trajectory in an unpredictable direction.
The good news is they hit an organic object HARD and second shots tend not to be necessary. The bad news is their unpredictable secondary path if they ricochet, and keep on flying. This makes slugs very unsuitable for shooting in a neighborhood. I have absolutely no doubts a 49gr slug is capable of causing serious injury, or even death, to a human being in it’s path.

Great stuff, Hoot! I can tell you that you need to really respect the power of this gun, even with “pellets.” A 31fpe .22 of mine, shooting 18.13g JSBs has hit a maple branch at 50 yds, ricocheted 90 degrees and did property damage 70 yards from where it impacted the branch. According to a Russian Airforce Condor shooter,both H&N Barracuda and Grizzly groups tightened after removing the LW barrel’s choke. According to him the .25 JSBs group got larger.
:hoot:
I used one of Neil’s 9″ LDC on it to very good effect. TT Tony also makes a similar length unit, and I tried a Donny Du’s carbon fiber 6″ as well. All get the job done…but all most effective in the longer lengths on this particular gun.
There’s so much air coming out behind that pellet, I have four holes in the frame to vent some of it into the forearm.
The one conclusion I came to was you need a full 9″ of LDC to make this rascal quiet…really quiet.
However, without the moderator, it a 27″ ass kicker…a bit loud for the neighborhood, but if you get out in the woods it’s really handy. The lead slugs are too dangerous to shoot in the back yard. 72 fpe is more than I need unless I want to shoot a deer or hog. I’m sticking to pellets of at least 31gr. They flatten out nicely at just about any range and drop on the spot. That way I can avoid ricochet’s due to the solid mass and weight of the heavier solid lead slugs, which tend to want to keep on trucking after they hit something solid.
Personally, I was surprised at the long shot count! Maddog Doug shared a couple of his secrets with me to get that bell curve just right.
Did chopping the choke off the end of the original LW 18″ barrel make a difference? None that I could tell. I was hitting a 12″ square seawall block at a lasered 263 yards with nothing more than a red dot scope. I could tell by the water spouts when I hit short. A bit of holdover and I was smacking that block on a regular basis. Anyone could have done that…it’s just that the gun is capable of really reaching out with that 16″ barrel.

Very nice Hoot, good seeing your project come out nice. I thought you had a Neal ldc for it?

Yes, things are looking up! Lots of shots per fill, now. At PW-4*1, with 31 grain pellets, the first few shots are averaging right at 1000fps. I’ll try to do a full string sometime, but I needed to get outside and shoot before it got too dark. Even though this seems high for the Baracudas, 890-930fps is what I believe that I read that people like to shoot the waisted pellets at, they are still grouping into 1″ at 50 yds. I haven’t tried the Grizzlies yet. I’ll let you know when I do.
