Weihrauch choked barrel like Monsters REDESIGNED

[skorec]

I swapped barrel to Weihrauch choked one at my Puncher ONE   
(https://www.gatewaytoairguns.org/GTA/index.php?topic=142379.msg1497027#msg1497027)
and with .177 Monster REDESIGNED and 100bar regulated bottle I have  reached my best five shot  group.  I was so happy that I added  the sixth shot which flew up a little bit.

Very nice shooting for the .177!

I think you found your barrel   I was thinking that barrel should do well, when posted the pictures of the pellets you pushed through it.  That is a very good group!

Today morning I changed bottle to 160-170 bar output air pressure and .177 Monsters REDSIGNED  started to run at higher velocity.

The grouping is opened a little bit :
1.    At 290m/s up to 1 MOA
2.    At 305m/s up to 1,2 MOA but whit one 5cm flyer too

Also I have tried 21gr Piledrivers at 285 m/s but accuracy was horrible/too danger.
For them I will need to swapped always  to NCH POLY barrel.

I really like those pellets through my DAR177, it's laser accurate

Peter, that is some very good shooting – of both the gun and the shooter!
Congrats!   

It seems you might be ready for membership in the NUAH club!

(I still need to practice some, I just tried the 100 yards last weekend for the first time. It was fun!)

Thank for invitation but I am not competitive man and also only few of my targets are so good.
Maybe later.

My  Weihrauch choked .177 barrel is  635mm x 12mm , TR=1:16,3 is a litle bit ticker than LW barrels  .
 Which barrel do you have on DAR177 ? 
Which spead do you use for Monsters ?

[skorec]

I have removed WH  barrel to my Kral Puncher Pitbull base which offer also magazine.
Unfortunately the accuracy of Monsters has decreased  2 times.

I am thinking that case by barrel vibration and probablly I wil nead to add some DAMPER.

I have RE-BARRELED several PCP's with WEIHRAUCH barrels and am yet to be disappointed ... They have always shot fantastic !

Are all of their barrels 1:16 twist?  That may be something I need to look into for NSA .177 slugs.  I'm thinking maybe it would behave better than the LW 1:17.7 twist.  I got the 21 grain to work at 40fpe, but it would be nice if I could get the other weights to work at lower power levels too.

Twist at Weihrauch barrels is  a little bit faster then standard LW barrels but not 1:16.  Also choke seams to be tighter . Unfortunately all  .177 NSA bullets are shooting very bad.

Didn't you say it is 1:16.3?  I was thinking about the unchoked barrel too.

[skorec]

Probably yes and  if then it is true .
But probably NSA  and Piledrievrs  are not shoting from my barrel vell because I have choked barrel.
