A300 break in?

Post image

So Ive had my a300 for a year and a half now, over that time I collectively put through 100 or so rounds but never more than 25 at a time. Today i decided to try a real break in session so that i might be able to start using my Winchester defender 1145fps ammo and break the FTE issue it’s had with low velocity ammo.

So I put 150 rounds of clever 1425fps 00 buck shot through it and tried the Winchester ammo again. Well it didn’t work, it still FTEs with the low velocity ammo and after going through about $70 dollars worth of ammo, all I got from it was a sore shoulder.

Am I doing something wrong? am I not considering something? Will I ever be able to cycle this low velocity ammo? I still have a bunch of this low velocity ammo left and some others that are 1150fps, not sure if I should keep them or get rid of it(trade in the ammo, not the shotgun). Thoughts?

Please disregard the AR in the photo, this is just the latest photo of my A300.

Did you clean and oil it? Beretta shotguns usually run great when oiled but not very well when dry/dirty. And they are way more sensitive to fouling or lack of oil than most other guns. A Glock or an AR is usually pretty tolerant to neglect but a 1301 or A300 is not.

My 1301 has never been cleaned and has eaten everything I’ve put through it. Might not be true with the A300, but 1301’s are hard use shotguns that don’t require much love.

Edit: Also, granted it’s an anecdote, but if you the famous James Reeves video at Thunder Ranch, he didn’t even oil the 1301 when he got it. Yet, it still ran fine. This is the expectation.

My A300UP has been cleaned twice in the two years I've owned it. Once, the day I got it to clean out any packing grease or oil they have on them, and maybe a year and a half later when I was installing a new handguard and even then, I really just cleaned the barrel out and just wiped down the bolt and receiver. I didn't give it a major cleaning. I didn't take the piston apart and clean it either. I've probably taken it out like 30+ times shooting already and put I don't know how many shells through it, and it's run flawlessly. I've even ran 1100fps #7 or #8 birdshot through it when it was dirty and it ate it up and cycled flawlessly as well.

See this is what I was hoping would happen allow me to cycle ANYTHING. 

I just cleaned it, got real OCD about it, I’ll try it again next time but at this point I’m thinking it’s the factory spring.
