I would wait and deprime them on the press. Don't rush into it. It doesn't take that long, plus you can resize at the same time.

That would work. Be sure to check local ads and yardsales. I picked up a rock chucker ages ago for 40 bucks, came with a pile of bullets too.

The Lee hand press is VERY cheap. Lee also makes a kit w/ included dies (may be cheaper) that simply use a provided hammer to do all the work. I wouldn't be surprised if they had a depriming die for those. The Lee Challenger press (which I use for 5.7) is great because you can swap dies in seconds w/o having to mess with screwing them to the proper length each time...similar to Hornady Lock'nLoad. It's like $30-40 new. There's also an new Challenger cast press that's much much beefier...great for larger rifle calibers.

When you get them, don't go all gung ho on it, deprime, clean, prime, and load up about 20-50 of them then go shoot them to make sure they function. You don't want to load a thousand rounds to catch a mistake at the range.

The hand press sucks for doing anything more than 5 rounds, lol. Get the bench mounted press, you will thank me.

I didn't mean for sizing tons of cases... I thought he was looking for something cheap to deprime with before he got his press (did you order a Dillon or did I imagine that?). W/ a simple depriming die it wouldnt take nearly as much energy to use the hand press. That being said, I've never used it so you would know more than me about that.

I don't own one, I thought about it for a while to load target rounds at the range, until I tried one. Anyhoo, that press he is ordering is bench mounted and cheaper than the hand press kit. Can't go wrong with having a single stage around anyway.

I edited my earlier post to recommend the Challenger breach lock press. It's cheaper than the Rock Chucker (although perhaps not as sturdy) but the Lock'nLoad type system its a huge advantage to not have to screw in the dies every time. Mute (sp?) point now if he's already placed the order...

Grant, I have NOT ordered the Dillon yet. My plan was to start ordering everything for reloading slowly. The goal was to have everything I need by winter. That being said, the first things I wanted to buy was all the stuff to get the brass ready since I already have a few thousand cases.

So I figured I would buy everything I would need for the brass up until the part where the brass goes into the Dillon. I.E. cleaning, trimming, etc, etc.

That way as soon as I do have everything I need I can rock and roll. First thing Im going to do is buy a small bag of 9mm and load that. Maybe 100 rounds or so just so I can learn the equipment and fundamentals and not blow my hand off. Then jump into the 5.7.

Edit, one more thing as to not confuse anyone. the Only reason I was looking at the single stage right now was for de priming. Again, for a total of 50 bucks or so I could get the single stage and de priming tool and at least get a jump on case prep.

Hey now, no raggin' on my hand press, I've loaded probably 2K rounds with it, besides, it gives you a pretty decent work out as well. :D

You could always send some brass to me for case prep :D I could also send you my own prepped cases for slightly more.

So I got the ABCs or reloading yesterday. Read it twice. It has made things a lot clearer on all the steps and the different ways to do things.

I was curious. Does anyone have the Full Harnady LNL setup with the Bullet and case feeder? I have been watching videos on it and that thing really pumps out some ammo. I was curious how this works with the 5.7mm. I read from one of keymasters posts that priming and re sizing does not work on the LNL though. So all cases would have to be preped and sized. But once all that is done it is pretty much how fast you can load raw materials and pull levers...

Im starting to see a glimmer of hope that my poor butt may be able to shoot 5.7 on the weekly basis instead of once a month after I check for loose change in all the couches...

Nothing wrong with the Lee Handpress as long as you don't over do it. More than enough for sizing 5.7 and pistol cases. .223 and .45-70 is fairly easy with it as well. I tried to use it for .50ae and thought I got the case stuck in the die. I will never try that again. Like to never have gotten it open.

Just got off the phone with Hornady to get a LNL plate. The good news is he made an extra plate whenever the last order was placed, the bad news is it was a little more expensive than I thought. I thought they were like $119 shipped. I think my total came out to like $135 after shipping. Ahh well.

Aren't you supposed to size seperately with that set up? I guess it doesn't matter if you are having to trim.

Vette, I really dont know as I am kind of flying off the seat of my pants. Never reloaded before. this is how I am doing it.

On singls stage:
Decap
Lube
resize
trim
clean primer pocket
clean

On LnL:
prime
charge
crimp



From all my research I believe this to be the correct order...

Might want to seat a bullet after charging :D .
Just messing with you. May I ask, how are you crimping?

And about the shell plate, it seems it has been posted before that the hornady LnL shellplate doesn't support the case enough (primer hole too big) and the case can get messed up. With the need to trim this caliber after basically every firing, I guess it doesn't matter.

Bullets are too costly for my blood. I'm loading spitballs for practice.

As for crimping, Im getting a die that is made from Grantness. He moddifies a Lee crimp die to work on the 5.7.

As far as the lnl goes, I have heard conflicting stories. The keymaster says you just can not decap. Then I read another member who's name slips my mind, said he does everything on the lnl with no problems. Who knows. I guess ill find out soon.

New to this forum, but not to volume shooting. I admit I've done far more pistol than rifle, but here is all I've done to successfully reload the 5.7:

Redding 2 die set
Hornady One Shot Spray
Single stage for now,rather than Dillon Progressive
RCBS powder measure
40 gr. V-Max bullet
Winchester AutoComp

The Redding dies are smooth and work well. Surprised how the bullet seating & crimp worked out (technique learned from Redding). Bottom line, all good (even without cleaning primer pocket). No case trimming to date after four reloads, just using Elite case gauge to tell me. Accuracy & reliability: excellent.

I've decided to use the new RCBS crimp remover tool (90386) in the case prep center. I can seat the primers w/o using it, but they seat easier, but still firmly seated, after crimp removal. And the primer will have a better seal in the case. I use a B&D cordless screwdriver and the Lee lock stud and cutter setup. I chamfer and debur on the case prep center with the new carbide tools.

Heres a bit of data from a recent outing...

AutoComp in the PS90 is nearly un-touchable for consistency, smooth operation, and reliability in all of my testing - and all of these rounds came out of the Dillon, so it obviously meters well...

5.2-5.5 grs of AutoComp with a 40gr Vmax is my prefered 'sweet spot' in the charge range to pull the most consistency and reliability...

--------------
PS90 - Triple Rail

5.5 grs Autocomp
40 gr Vmax
CCI400
SS197 Brass

2280 fps Average
9 fps Standard Deviation
N=15

Notes: Very accurate, ridiculously consistent...
--------------
PS90 - Standard

5.5 grs Autocomp
40 gr Vmax
CCI400
SS197 Brass

2234 fps Average
10 fps Standard Deviation
N=20

Notes: New(er) gun than my TR, getting a little less velocity probably until it breaks in a bit more...

Grantness and all others. I suspect we could find a linear correlation between the bearing surface of a given projectile and the mass of the projectile. We already know two "sweet" spots in this function: SS195 and SS197. One possible complication is that the two bullets use different density cores. It appears to be all about a friction to mass relationship, no?
Many of the different bullets in the mid 30 grain wt. range appear to not work well in the blowback action because this relationship of bearing surface to mass does not allow the bullet to "tune" with the pressure cycle of the Fn pistol. Probably true for the rifle, have not gone there.
will think more on it, and maybe run some figure if I can.

iFire, if you do not mind, could you post a picture of the projectiles in question side by side (40gr vmax, 35gr nlf, 35gr nxt, and possibly the 28gr ss195), it would probably go well with our discussion.

Best part about working for a construction company is when there is nothing to do, you get to build stuff.

Started my reloading bench. 1' thick MDF for the top with 1/16'' steel on the top. The will be a 1' deep cabinet and shelf across the back of it. Lets are getting made from 4''x 4'' green treated posts. All crap we have laying around the garage...

looked at the Lee case trimmer system. Interesting, especially due to the possibility of using an electric drill to power the thing. Does anyone have some first hand experience using this system? I am concerned with the OAL changing with trash and such on the inside of the case at the primer flash hole. Most of my .308 cases have a a lot of "stuff" on the inside of the flash hole, and I suspect that would be a bad thing with this case.

Max chamber pressure on PS90 is the same as the FsN right? (50KPSI)
When do mags start popping though? Anyone do tests on that for the PS90?

So, I'm reloading 40gr VMAX over longshot and I was using iFire's data, it has been performing great but I'm curious the opinion on if this looks like normal shoulder setback:
Image
The case in the middle is a resized case as a reference. I've just read comments about shoulder separation and wanted to be sure I wasn't risking any issues before I loaded a couple hundred of them.

EDIT: I measured a resized case from the shoulder using a .28 comparator and the resized case was .932, the fired cases were in the .975-990 range. seems like a lot of movement to me, but I'm not sure how much is normal for this cartridge.

Pretty normal. Shoulder movement will be greater even more when fired from P90/PS90

Those are fine. If the shoulder is about 1/2 way up the neck (more or less), that's when you should be concerned. But like Jay said, depends on the gun used (PS90/AR57/FsN/TC)

Yeah, this was with my PS90 so I guess I'm doing pretty well then. Time to ramp up the press! I have about 200 cleaned and trimmed cases waiting to go :)

Thinking I'll run 250 SS190s next, since I still have about 900 from my 1000 order. So many projectiles, so little time...

EDIT: is there a way to reduce the shoulder setback without affecting feed reliability, perhaps with a slightly stiffer recoil spring? I imagine if one was to be made it would be on EA's site, maybe I missed it... I think I saw there is a heavier weight for the bolt as well...

We have both a heavier rate reducer and heavier springs. In this case I would leave the recoil springs alone! and go with the heavy duty rate reducer.

Grant hasn't dropped in for over a year unfortunately but from this thread: 5.7x28mm Reloading
Grantness wrote:The IMR powders are more than likely too slow... Unique is too fast.... Best powders I know of are HS7, True Blue, Blue Dot, Acc#7, VVN105, VV3N38, Longshot, and Alliant ProReach looks good so far, but Im still testing...

Recently worked up a decent subsonic 5.7x28 load for my AR-57 SBR (9" barrel) for use with my Gemtech SAR57 suppressor. Two powders worked pretty well, but case prep is a bear. Not an easy or quick round to reload. Used a single stage Hornady press I found on sale on Amazon. I do case cleaning one day (simple green/water soak and agitate for 10-15 min then water wash and dry), sizing and deprime second day, hand prime on third day and powder measure (with powder trickle by hand to get charges EXACT) and bullet seating on fourth day. Use Lee die set. I didn't crimp but Lee makes a crimper if you so need.

First:
Powder: True Blue 3.0 gr
Bullet: Hornady 55gr FMJ-BT
Case: once fired American Eagle
Primer: Winchester small pistol
COAL: 1.575

Second:
Powder: Power Pistol 2.8 gr
Bullet: Hornady 55gr FMJ-BT
Case: once fired American Eagle
Primer: Winchester small pistol
COAL: 1.575

The true blue is very fine grained compared to the round flakes of the power pistol. Both burn pretty clean and leave little residue with the TB being a little cleaner. These loads are just enough to cycle the heavy, heavy AR57 bolt (it's a simple blow back design) but remain subsonic through the 9" barrel. Be careful not to remove the case lacquer by tumbling them in case tumbler. However, I also apply a little dry lube spray to the rounds just before loading into the FN 50rd mags to help feeding. Seems to help a little.

As always: Use these loads @ your own risk.
