Slug liner. I had the fx slugs shooting at 965 FPS and submoa at 100. Also the redesigned jsbs at 930. All shooting great with my external plenum. I just changed the spring out for the shorter that came with the power plenum. Also getting some of VK extra large hollowpoint slugs and his fx 28...

That’s kinda what I was thinking. I’m gonna change it over and try shooting it. Thanks

Finally got the power plenum installed on my .22 impact. Used the old hammer spring as everyone said that will give the better power even though the biggest slugs in my arsenal right now are 27.5. Started tuning to get around 960 for the fx slugs. Got 960 at 105 bar and turned the valve adjuster...

Finally did some mods on my early impact mk2. New hammer weight, delrin C3 bumper, and bigger 6.5 mm valve seat. (Already did the elongated port. Mine had the 5.5mm valve seat. Put everything back together. Left the barrel off and had a leak coming out of the valve housing. Cocked the gun and it...

Sorry I missed that. Thank you for the responses and help. I’m gonna change the valve seat( I have an early MK2 so it isn’t integrated) , modify the valve housing, change the hammer weight and C3 bumper and add an external plenum. Then change it to the power plenum whenever it arrives. 

Thank you. Makes me feel better. Have a good area to work on just always afraid a part will go falling out

First time tearing down my Impact. I have an MK2 I’m going to add a HP kit until my power plenum arrives. Starting taking it apart and almost looks like a bumper is missing. Searched all over and can’t find it so my question is something missing or am I just being paranoid. Thanks. 

Want to buy a 30 cal setup. Will pay shipping for right deal. Paypal

So I’ve been playing with my impact mk2 and tuning it for slugs. I keep reading as much as possible on the harmonic tuning. I have elongated my tp and pellet probe which has let me lower my reg pressure. I was wondering if a lower reg pressure with the valve open longer or higher reg with the...

No problem. Glad it helped. I’m still playing with different weight slugs and settings. I’m currently making my own slugs at different weights and trying them out. It’s fun and a pain at the same time. Hope to have it dialed in soon

I recently modified the pellet probe and transfer port as Heavy-Impact as shown in different threads. Before I was 150 reg, hammer spring not maxed but close and was shooting 24 grain slugs at 920. I was getting 3 mags. I do have a 600mm slug liner. After elongating the TP my reg is set to 130...

900 is plenty for far shots. Once you have muzzle velocity and a starting bc it doesn’t matter the range. Get StrelokPro and a range finder. Also someone posted an article that showed around 900 FPS MV was the best speed for less wind drift. Only two mags on a full tank? Sounds like you are...

I now have a 600mm impact mk2 but originally had a 500mm wildcat. The .218 21 grain NSA around 900 FPS with the slug liner were one hole. 

i have a wildcat mk2 with mods for sale. $1000 purchased new this April newly added: 4-16 leapers scope plus (1) 250 ct of Hades pellets Good: -pellet liner with no shots through it -huma regulator installed (also have old regulator and plenum) -500 mm slug liner -fx stackable...

Yeah I know I can get a different base punch. When I go on the site it makes it seem the nose and base punch come as a set and you pick what you want. Since I’m only interested in 1 E hollowpoint I would get that plus either flat or dish base. The 1E HP option is an additional 75 on top of the 75.
