.177 Taipan Veteran Accuracy Testing

[elh0102]

I expect you can tune it to handle the 13 gr at a higher velocity, but you might give up a lot of air efficiency. And I'm not sure that has anything to do with your flyers. It ought to shoot the 10 gr pellets well. If the issue with flyers is improved by barrel cleaning, but doesn't last long, sounds like a barrel issue to me. If no correlation with cleaning,  maybe have another experienced shooter try it, just to rule out a possible issue with bench technique.

Illinois.  I understand completely.  Worked for companies in Northbrook and Mundelein.  Well, just know that a whole new world awaits you in Texas if the Illinois thing doesn't work out.  Come on down.

The second I can convince my better half to move to a more hobby-friendly state, I will do so!

Diaryboy was right about the safety. The rail must have slid just a minute amount, but I've got it back to where it was and the safety is function as it did out of the box.

I have put about 350 of the 13.43 JSB through it in the last two days, culminating in this 60 shot target, shot consecutively. Out of those 60 shots, I would call 3-4 of them fliers, which is acceptable considering I was using the magazine. I did make a scope adjustment between rows 2-3. These shots are all shot consecutively in one fill, so I feel like it was a good test.



I must have not been using UTAG Lab Radar correctly yesterday. I put the gun over the chrony at my work and it maxes at 850 with the JSB 13.43 and is using a ton of air to do it. I originally backed it off to 840, but it was still louder than it should be and efficiency was at .9, really low for this gun. So I backed it off a bit more and settled at 815 fps. I'm now getting an efficiency of 1.2 and the gun seems to be "dang" near half as loud as it was at 850.

I think we can safely call this saga over. I am going to put a few more tins of 13.43 through it and revisit the 60 shot grouping paper. Until then, I'm just going to smack pests with it and forget about groups for a good while.

Well Folks.
I bought the 177 short from Chris and I encountered all the same issues.
So I went to work testing.
Short story is the reg is leaking.
Es was all over and shots when filled to 3500 were 900 FPS and when tube psi went down FPS drops below 850.
Reg was set at 110 bar and would not hold a psi in the tester.
I took the reg from my 25,set it to 105 bar , cleaned the barrel and the gun became incredible.
Es of 4 on the 40 shots I took at 895 FPS with 10.3 g and one very small hole at 30 yds.
I have one of the 5 177 mutants and it is awesome as well.
I’ve owned over 20 taipans and this is the first issue ever. Probably just an oring will fix it.
I’ve own almost every pcp(well a lot) and taipan is the best.

That breaks my heart man. I'm so glad you were able to figure it out, since I don't have a reg tester. How I wish I could afford to make you an offer to get it back. Please enjoy it!

[deathwizard]

Well. It can be bought.
Can you believe that the mutant and vet share the same reg O-Rings.
I have mutant O-Rings so I replaced them and set to 135 bar and installed it in the 25 vet and its working great.

Excellent!  Glad you were able to put your finger on it.
