I swapped barrel to Weihrauch choked one at my Puncher ONE

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 :D 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 ;D
-
Peter, that is some very good shooting – of both the gun and the shooter!
Congrats! ;D
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 ?
-
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.
-
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.
