I bought a FA 454 back in the late 80's and poured a pile of full tilt rounds through it. I ended up sending it back to Freedom Arms three times for repairs in the first two years that I owned it.
I don't think most guys that own them, actually fire thousands of full power rounds through them like I did......or they wouldn't have a very good reputation for durability. I finally gave up on it and sold it in about 1999.

Fast forward to 2019 or so and I bought another in 475 Linebaugh and one in 500 Wyoming Express. They are both really nice guns and since I don't shoot either one very much, they haven't broken yet.

Run it up, until you blow it up, then back it down a bit.
