    I've got the pistol and pup. When I got them a box sold for $21 now I see them for $30. When I got them, presents from Dear Wife, I also got the dies. I recall that this is a finicky round. I hear that too much polish on the case will affect the load and that the pistol can be easily over pressured. I've seen the blown pistol barrels. I'd still like to try. Any thoughts, links or suggestions?

    If you use good handloading practices and full length size them, you ought to be fine. I have heard that you have to trim almost every time but other than that, people get into trouble trying to push it or with double charges. The guns are blowback which is usually very forgiving but in this case they have built them with rather light bolt/slides, the slide on the pistol being even more on the light side. So, my recommendation is to work up loads until the pistol likes them and stick with it.

    Do not polish, leave coating alone. Soap or a little simple green is your friend. I Trim and load with cfe pistol in the latest and have had good luck. Hornady sizing dies worked best for me.

    I have been curious about this round. Is that coating on the cases some kind of lacquer? If so, how does it survive repeated trips through the sizing die?

    Just FYI, SGAmmo still has 40gr american eagle at $20.95/ box or $199.95/500. In case you want to load up on some cheaper factory ammo while working up your loads.

    The coating on the brass has nothing to do with feeding, it is merely a preservative found only on FN ammo, other companies load the 5.7 and they do not have it. It may change they way a particular load extracts, slightly, but if you work up your loads with or without it, they will work fine.

    25, do you have any good loads for the 5.7 you would recommend. Also curious about your thoughts on the coating, I have never seen 5.7 ammo without it. Does anyone else make it besides fn and federal that I am missing?

    I'll tell you one sure thing about the coating....if the coating is scratched up on reloaded ammo, it WILL cause feeding issues.

    Some people swear by completely removing the coating. I haven't tried it personally. When I reload a batch of 5.7x28 I carefully inspect the brass. Any that have the coating scratch either go in the scrap bucket or put into a "rainy day" stash. I've tested ammo with a scratched coating, factory and reloaded, and it always causes issues. But I haven't gone as far as tested ammo with zero coating.

    5.7 reloading quirks

    Look up Jeff Kelley and others on Youtube for tutorials on 5.7 reloading. All the details on the coating, sizing, loads.
