Thank you for the information!I have read several articles on reloading the 5.7.
long story short is don’t do it, among other things the factory round uses a proprietary coating.
I use a RCBS Jr and a Rock Chucker with Small Base Dies and Lil Gun powder, wide variety of bullets.. mostly just plinkers for grand girls...so have not chronographed of adapted for accuracy.Wondered if anyone out there is currently reloading 5.7x28 and what if any difficulties you have encountered? Also what brand/type press you are using? Thanks!
I reload for my ps-90 and safe loads (practice) for my FN 5.7... I use Little Gun powder and measure via scales each charge.. small base dies are a must and extreme care should be taken both in marking and storage so that the PS-90 loads never come near the FN 5.7 loads or pistol. I have been reloading over 40 years.I have a friend who is successfully loading it. I have been loading for almost 20 years off and on, but don't feel comfortable doing it. He has been reloading for about 40 years and is on a whole different level than I am. Definitely left to the professionals or highly advanced loaders (which he definitely is!)l. Long story short, it can be done, but there is little to no room for error. It is absolutely not for the casual loader or one who loads regular pistol rounds only. With the pressures involved and extremely small tolerances, very slight differences such as those described above can have catastrophic results. I would not recommend it for 99% of us who reload. Just my .02!!!
