Taipan Long .25 discovery

[Pickzilla]

Hi all, 

I bought a Taipan Long .25 about 10 months ago. I shot it a bit, but got totally preoccupied by a few other airguns. My long was weird. It would put MK2's at 900 fps into half inch groups, but then, some ridiculous flyer would happen like 2-3 MOA off. It really had me perplexed till now... I finally brought it down to my indoor basement range and started the troubleshooting. 

Shot NSAs, MK1 and MK2, VK 33 gr, Hornets, Kings, H&N hunters... Nothing was consistent. 

Decided to clean the barrel. During, I decided to take a look inside. Def best idea I have had. The factory moderator had seen only a few hundred pellets/slugs, but was absolutely coated in lead dust. So was my Donny Sumo. Something was amok. Looking closely at the factory air strippers, one was bent and clearly clipping. PHUCK!!! 

I took them all out, and tested with the Donny and without. Was definitely the OEM air strippers causing the problem. Tuned it without them, and there we had it. Decided to shoot her without either moderator with MK2's, and sure enough... pellet on pellet 20 yrds. 

So relieved I found the issue. It was utterly frustrating until now. Tweaked the HST. Took it out to 50 yrds with NSA 26.5 gr and MK2's, amazing accuracy... 7 to 10mm groups with both. 

Now thoroughly in love with this gun. 

String is 15 .25 FX Hybrids. Target is 15 at 20 yrds.

Looking at the same gun, does the sumo make a noticeable noise difference ? Like is it day and night difference.

They are not backyard friendly without an LDC. Even when turned down there's a POP to it when shot.

I just purchased a .25 Taipan Long w/Sumo, but have not had a chance to fire it yet. So I am guessing my neighbors are going to hear it easily when I fire it? Would the extender from DonnyFL for the SUMO make it quieter? This sucks!

Remain calm and don't panic! I have a 25 long,a 25 standard and a .177 standard. I don't find them very loud at all. I also don't have anyone around me.

Indeed! As loud as a .22LR!

I've got a huggett attached to the factory shroud on my standard .25, and find it to be very quiet. Its even pretty good with the factory shroud removed and just the huggett. I have experienced a clipping problem though. Taking the huggett off and on loosened the shroud a bit. I re tightened the shroud and tightened the set screw and that seems to have solved it.

Are they louder then a springer ( no moderator) hw97 in .177 ? 

 

[Pickzilla]

With a sumo you’ll be just fine. Pellet hitting is louder.

Thanks!

@Pickzilla this post has eerily good timing to me, as I have experienced similar "flyer" behavior and pellet instability at range with my .22 Long and last night I took off the factory moderator for the first time (after ~1500 shots) and saw a lot of lead residue on the barrel and inside of shroud.

• If it's not too much of a hassle could you post a picture of the damaged factory air strippers? I am not sure what you are referring to exactly. Do you need to take the shroud apart to see this or is it noticeable from looking in shroud with a flashlight?
• Also, I'm glad that you/we found the issue, but my next question is: now what? Does this constitute warranty repair, or is there a quick fix?

You are teetering that OEM shroud with added weight up front by adding a too heavy LDC. Trouble was waiting to happen. Use lighter weight thread ons like Huggett and HW for example no issues not too heavy up front.

Too bad Falcon no longer exists because their silencers were the lightest and copied the internal design from the best MOUSEFART silencer maker in the world and made them thread on or slip on with grubscrew.

NO LDC OR LIGHT WEIGHT LDC

HEAVY LDC ☝

Noise is Very subjective. Quiet to someone is too loud to others. If im shooting more than a few shots, ill turn on some music.

Nice job troubleshooting, glad you got it squared away. Looks like that rifle a real shooter now that nothing is swatting the projectile on the way out!

Mink, 

Sure I'll get you a pic... bear with me though this weekend is a bear for me. 

Yes you have to take the front cap off the factory moderator (after you remove the mod from the gun). The aluminum rings inside are both baffles and air strippers. Just upend it and let them (gently) fall out. 

No quick fix for me... I would have to try to bend the metal back into place, and I'm sure that would screw it up just as bad or alter airflow dynamics. I only need one factory replacement stripper... I have a feeling it's going to be not so easy to find. 

No real urgency there though, gun is seemingly fine without them in. Took a grey today at 50 yrds with a .25 hybrid... man did that hit with authority. Loving this gun now! 

@YO Not noticing any droop with the Sumo.... unlike when I slapped an Emperor on my 700mm Impact. Ugh. Mis-steak....
