Q:

Machined .25 blank LW barrel

Just recieved a machined lothar walther 25 Cal barrel (Machined from blank) for my shadow and fitted it but can’t obtain any reasonable grouping. 3″ at 27M! My 22 does sub .5″ groups. Any suggestions deeply appreachiated.

Do you have any baffeling in your shadow?

If so check it for clipping also

My .25 Tony barrel wasnt doing as hot as I thought it should accuracy wise until I removed my mod on it…. groups just great now.

May be worth a look as Walter said.

The first thing I would check is the crown.

Yah! What Voltar said. Check for the choke. Push a pellet through the bore with your cleaning rod. You should notice it get tighter twords the muzzle end when you start the pellet from the breach end. You could have the barrel in backwards . That is , with the choke at the breach end.

remove your silencer first off. Have a discussion with whoever supplied said barrel about how it shot for them.
Check pellet fit and push some through it and make sure it never gets loose on the trip down the bore. Hopefully it tightens up in the last 1 1/2″ if the barrel is choked.
Walter….
