5.7x28

[Jetman]

Those of you that shoot this round know it is backordered at just about every supplier. I am looking for reloading specs for this round to shoot thru my FN five-seven. Anyone have specs they would like to share?

If I remember correctly, you can't tumble the brass. I believe there is a coating on the brass that needs to be there for function. I could be wrong though.

I really like the 5.7 pistol and P90s but dont like the cost of ammo or the fussy reloading issues. Yes it does have coated brass. The above vid and other info turned me away from 5.7 firearms.

go buy a pmr 30.. similar ballistics with the ammunition most commonly available to the civilian population.

Case Coating

Yes, I knew about the Case Coating, and am set up to hydrostatically clean the cases. I am getting lots of feed back, both positive and negative, on reloading this cartridge. If the ammo was more readily available, I would buy factory, and spend my time on the other calibers I shoot.
I it seems overcharging the case is the biggest sticking point that keeps coming up. I have an RCBS digital Powder Measure and scales that I think I would probably use on this caliber to charge each one with an individual measured powder charge.
This one does seem to be the mother of all "paining the neck" calibers.

Caveat: I am not a reloader. may never be.

But I AM interested enough in it to pick up tidbits here and there. What I've gathered about this cartridge is that it is VERY unforgiving. Charges must be "exact".

I know you currently reload at least .45ACP and .38/.357 - but the 5.7x28 is much less forgiving than those.

Is your current measuring set-up precise enough for the 5.7? (just a generic question?)

I suggest the fiveseven forum for advice on reloading the 5.7 round. Be very cautious as some of the loads listed are for Thompson Contender and posts do not always identify this. The only published load data I have seen is in Lyman's 49th (thanks to Broomjm for putting me on to this) and the Ramshot web site. My starting load was based on the Ramshot website data as it was lower than the Lyman data. I use a 10% solution of Simple Green in an ultrasonic cleaner for no longer than 15 minutes.

This is my recipe that closely duplicates the SS197SR round and is what I normally use for plinking:
Hornady 40 gr V-Max or Z-Max bullet
CCI 400 small rifle primer
5.1 gr True Blue powder
COL: 1.580"
This gives an average velocity of 1668 fps out of a FiveSeven pistol compared to a SS197SR factory round velocity of 1662 fps under the same conditions. The chronograph was located 17 feet down range.

To date, I have loaded over 700 rounds. My reloading cost per box of 50 is $7.52. It is the most cost savings percentage wise of any round I load particularily now that ammunition for the 5.7 is almost made of unobtainium and when you can find it the cost is high. Eventually, I will need to purchase more factory ammo just to harvest the brass.

Good job...... now he's going to be us confused.

What kind of dies, case trimmer, shellholder's, etc are you using for it? I checked out Lee's website but I can't find anything for the 5.7...

What I use;
Dies: Hornady
Shellholder: RCBS (don't waste your time with the Hornady as the hole is only 0.008" smaller than the base of the case)
Case Trimmer: Little Crow Gunworks WFT

It was my understanding that Lee made dies for the 5.7. Other die mfgs for this are RCBS and Redding for sure. Not sure if there are any others. RCBS is enticing for their rebates and Hornady is enticing for the 100 free bullets which I max out my return with .308.
