CZ Shadow 2 - 147 gr tumbling - 9mm/38 Caliber - Brian Enos's Forums... Maku mozo!

Thank you for the link.

The 147 grn bullets are .357 and were pushed with 4.0 grn of N340 .(4.1 is the published maximum)

I guess all the factory stuff stuff was too. Fiocchi dosn't have a great name for accuracy,it groups ok in my Sig but with Geco its literally a one hole shooter.Sellior and Bellot and Geco are about equal in quality and price,its what alot of shooters are using here.

My mate is bringing some Speer cartridges and some Nato Ball.

We have removed the human error with the Randsome rest,but for not getting any groups and with a spread of about 12" with everything tried its the gun thats playing up.Looks like the crown is dinged as the fingers on the bush look good and everything else looks ok.

Being produced in the 1970's it was likely made with pretty mild 124grn cartidges in mind.
