I have ran around 500 rounds through mine so far.
I have had problems with the Winchester universal shells,
But it eats the cheap federals with no
Problem.. Also had 3 out of 6 Wally World slugs
FTF and FTE it was the first six slugs my barrel ever saw.
With slugs it shoots high and left... Still need to play around with
Different ones and see which groups best.. I dove hunted with it all season
To get some rounds through it and get a feel for it!
I like it, I'm happy with it for now I run the Carlsons extended
LM choke.. Does me real good! No problem with knocking down steel
And tore the dove UP!
