So I started building my prod for more power because of a week long airgun hunt I'm going on in September with my friend. We plan on only eating what we hunt so I wanted to make sure it could take a medium sized animal like a porcupine no problem. I finally got it put together tonight and shot a string over the chrono and was pretty happy with the results. Here's what I have done to it~
Hill valve & .120 tp. Huma reg set to 135 bar. Tss and I honestly have no clue what springs I ended up using but I think one is the spring I ordered from hill. Honed air tube and polished hammer that came with the tss and some graphite. Here's my shot string from 3000-1800psi.

I have Jim Gaska making a 15" barrel and longer shroud so the fps should increase a bit when installed. I hope to have it soon.

That should do it! Good work! I have almost the exact result with similar mods. My Prod is unregulated and that's the only difference.

Can't argue with that Phil. I wonder how a regulator would do in yours?
-
So out of curiosity what's a porcupine taste like?

I've never ate one but I've heard they're really good ???
-
Wayne, Maybe we have eaten it. I did a google and found this??, correct porkies are not at all bad table fair. Folks back in Michigan made pasties out of them fairly frequently. A pasty is a finnish meat pie with potatoes, carrots, onion, rutabaga and "mystery meat. :o" I do Like pasties, And stop for them whenever I head to the UP. Jaa
-
Porcupine is actually really good. I shot one last fall and cooked it up like pulled pork. Everyone that tried it liked it.
-
One thing I'm curious on is would a mds hammer improve this? Rocker1 has them around 35grams I believe he said. Or would it be too light?
-

That might be next, but I generally use the prod for pests out to 25 yards max. I have a discovery tuned to 28 fpe for 20 good shots and a .25 AT44S 10 QE that averages 36 fpe for 2 magazines that is getting a spare air tube and regulator. So different tools for different jobs.

Same with me. I took quite a few squirrels at 25 -35 yards with my prod stock but I wanted it to be more powerful just incase of a bad shot. My mrod is what I use for longer range hunting if that's what I'm out doing. No problem out to 100yards with that thing. I use my kral for pest birds at my moms house for her but really don't shoot it past 25yards. I'm going to use it more this year for squirrel hunting.
-
Here's a pic of mine as it sits now. I really like the stock I got from lee also. It's going to help it fit into my backpack perfectly without having to remove anything like I would have with the factory stock. As it sits now it's a tack driver with 21.14 h&n 5.52mm pellets. One hole groups at 25 yards. And with the aftermarket carbon fiber shroud it's very quiet.
-
So I got my new 15" barrel and shroud from Jim at WAR today and got it installed a little bit ago. I shot some groups with a few different pellets and found that H&N barracuda match 5.52 shoot very well out of it. My velocity dropped a bit but with the accuracy I got I don't mind. I can't wait to take it out this weekend and shoot it out to 50 & 75 yds to see how it does. Here's a group of 4or5 pellets I shot at 25yds. I lost tract of the exact shot count but know it's either 4 or 5. It's the .25" group by the 6" mark on the tape measure.

Do yourself a favor take at least 5-7 lbs lbs of beans and same in rice... and some onion powder and basic spices like curry powder crushed red pepper and such.. ;) and a pot with a lid...
-
We plan on taking a bunch of stuff with us to make crazy dishes that most don't make in the woods. Things like fish tacos, pulled squirrel sandwiches, crawfish mac n cheese and what ever else we can come up with! But a curry does sound like a good idea!

Sound like you've been there done that!! Mrs dash comes in handy too😀
-
I have 5 or 6 different seasonings I'm bringing not including the normal salt and pepper. I'm pretty sure I'll be adding curry powder to it now though! Grouse curry would be a nice meal one night!
-
I figured I was done modifying my Prod until I started watching the thread Travis posted on the new ART/Sykes valve. I've got the TSS in my Prod already so it makes the mod even more tempting.
-
I agree. The biggest thing that has my attention is the cocking effort. It's not exactly easy to cock right now so if I can make the same power or more with equal or better shot count and reduce the effort needed to cock it then I'm going to get one.

Here is my prod with a huma reg stock internals
-
What grain pellets are you shooting? That's a good amount of shots

Fft 14.66 I could get more fps in the 700's 24 shots

from about 1982 to 1986 it was work thru the winter, living in rooming houses to save enough to spend from late winter to early winter wandering around from Jarbidge Wilderness area down to the Ruby Mountains and as far south as Zion national park...
a couple of those years was also spent on the east side of the Sierras somewhat along the pacific crest trail but more to the east... pretty much between Truckee and Portola but a few trips north and a few down to and towards Mount Wilson and Charlston...
only a few of those places did I have to keep my modded Benji .22 put away...
Then I had to grow up just a bit and raise kids best I could...
-
I've been to quite a few areas you mention. Did you hike the narrows in Zion? We're headed up to the porcupine mountains in the upper pensinula in Michigan because this trip was kind of a last minute thing. Last minute plane tickets and car rentals aren't cheap so we'll plan something to the wind river mountains next year when we have more time to plan.
-
Never been to the wind River mountains...grandparents spent some time near...
But know Zion top and bottom over about 8 mths based near Cedar city...My Honda SL 350(re-geared for road) got me to a lot of places like the Cedar Breaks and views upon views... canyons and flatish tops... I think the west rim trail and dropping down in is the way to go...

I guess now you have to have permits...

Zion is one of my favorite National Parks. :) I'm not able to do the chain at Angel's Landing though.
-
I hiked all over Zion about 10 years ago. Angels landing was something to see once you got all the way up top. The tour busses looked like ants from that high up! I recommend the narrows to anyone who is able to do it. I will definitely be going back again. I've been out west quite a bit hiking but if I had to pick my "favorite" place it would without a doubt be the wind river mountains. Look up big sandy lodge out there. It's worth the trip to go visit.
-
I wasn't familiar with Wind River mnts, but after looking them up, have been close. I have driven up the valley through Pinedale, on to Jackson Hole, Grand Tetons, and Yellowstone, a couple of times.
I am sure that sometime in the future will be headed back that way, and will have to check them out.

Been through all of those towns myself. Jackson hole is a real cool town to visit. I want to go back to the Tetons and hike them for a week or so in the future.
