New barrel for the 930... Trouble in paradise

[KestrelBike]

Still trying to figure out how to get my 930SPX to reliably cycle Winchester Universal. Two trips back got me nothing but a messed-up finish. Running a brake cylinder hone helped some, but still 10%+ failure. Might drill gas holes soon.

I dont think many guns cycle winchester universal well. My FN SLP (22") occasionally fails to eject fully (the empty shell will get caught by the bolt while exiting the receiver) and I've quickly stopped using them for competition. The SLP has zero issues cycling anything else and runs like a champ, I love it.

I just got the 10/22 XP hammer spring and will wring it out this weekend. If it works good I'll sell it, if it doesn't work as good, I'll sell it cheaper... I like the way it points but I am DONE with Mossberg.

I put a 100 round pack of Federals (#7.5, 1.125oz) through it and 1 box of B&P (#8 7/8oz) 125 total today with the new 28" Mossy barrel. It ran great, not a single malfunction where as before I was getting 1-4 light strikes within 25 rounds. IDK if it was the hammer spring or the ejector pin, but it is working now.

Crappiest ammo made. It runs in some side by sides.

I wouldn't buy a Mossy anything these days. And I've only seen two. A shotgun that when brand new wouldn't close without galling the receiver/barrel, and a .22lr "AR" that Mattel wouldn't even put their name on. That, and all the disappointment (I'm being polite) with the "JM". You KNOW that JM doesn't shoot an out of the box one in competition!!!
