YOU LOAD/RELOAD AT YOUR OWN RISK I AM NOT RESPONSIBLE IF YOU BLOW YOUR GUN UP OR HURT YOUR SELF :!: :!: :!: Your reloading procedures are beyond my control. I am not be responsible for your gun or your life /limbs/safty. As with ANY reloading project, start low and work up to almost a maximum load you should never load to the maximum since this is very dangerous.

I need some advice on a couple of things regarding the reloading of the 5.7x28. First, what kind of primers does it take (small pistol or small rifle)? Second, is it possible to reload with heavier bullets than what's listed above (55 gr., 60 gr., 65 gr.) for subsonic rounds?

I played a little with blue dot a few months ago, 10"bbl PS90 , cci 400 primers, 50 gr win PSP, just decided to post pic , since typing isnt so great, look at the pic and you will see handwriting isnt much better.

all ejected nicely, very pleased with the light loads at aprox 700 fps , work great thru the can here in the yard.



water filled cans at the three velocities for comparison, not at all scientific but gives a decent representation of performance on crow sized varmints

I have been experimenting more this morning with blue dot and 62 gr speer projectiles and with 3.2 grs am getting avg 940 fps thru the 10" bbl with suppressor. Seem to be very quite and accurate

I've only experimented a little bit, but I used the data from Accurate's site, only the start load of 5.7 grns of No. 5 powder with the 45grn sierra FB SP bullet, and WSR primers. Brass was once fired SS197SR's.

Initially, with the 45grn Sierra, there was a lot of case neck/shoulder expansion, and recoil was "noticable". Even though the newer bullets I loaded were only 5grns heavier, the commercially available bullets in this weight made me a little uncomfortable.

We reduced the load, and said effects lessened somewhat, but performance was not great. My friend who was coaching me at the time, gave me a vintage box of 40grn Sierra soft point bullets to try(can't remember which ones, I'm at work and the box is somwhere at home). Using the data for the 45grn bullets, the recoil, effects on the cases, and performance down range were more like the factory stuff I shot out of the box. I don't own a chrono, so I have no idea what velocities I was getting, but there were no adverse effects on the gun.

What twist barrel are you using?

I would like to know anyone has a starting and max load for a 55 grain 223 military bullet and unique.I have loaded for the FiveseveN for about eight years with v.v. 3n57 but would like to try unique as I load most of my other pistols with it and some times I have problems getting the v.v. Normally I find a load for a powder close and figure a starting load but I am afraid of doing this with such a finicky cartridge. I just want a plinking load nothing pushing the limit.

Thanks for any help.

Useing unique with a 55 gr. bullet

I don't know if anyone else is interested in using unique or not but I am bored to night so here goes, I was waiting to include velocity's but I can't seem to get my chronograph to work right now so no velocity's sorry.


Reload data for Unique and a 55gr. .223 military solid bullet in 5.7x28





Useing W.W. small pistol primer with unique powder
Strart load 3.4 grains no sign of over pressure
3.6 grains no sign of over pressure
3.8 grains no sign of over pressure
3.9 grains no sign fo over pressure
4.0 grains sign of over pressure small amount of primer flow(pistol primer
4.1 grains sign of over pressure more primer flow(still pistol)
4.2 grains signs of over pressure primer flow (pistol),very little shoulder movment and one small crack in one case, too hot

useing 3.9 grains of unique with pistol primer for plinking.

Useing w.w.small rifle primer with unique powder
3.9 gr. more shoulder movement than same load with small pistol primer.
4.0 gr. same results as above.
4.1 gr. same results as above but with more primer flow.
4.2 gr. same results as above ,even more primer flow.

Observations
changing to rifle primers didn't stop primer flow.
changing to rifle primers seemed to raise pressure(more movement of the shoulder)

useing w.w. small rifle primer with V.V. 3n37 powder

4.0 gr. no sign of over pressure
4.1 gr. no sign of over pressure, no shoulder movement
4.2 gr. same as above
4.3 gr. one case with a small crack at shoulder,moderate shoulder movement
4.4 gr. same as above

Observations
shoulder movement was less with 3n37 and rifle primers. Maybe the rifle primer ignites the powder more quickly a lowing pressures to drop sooner thus less shoulder movement.

As has been said before these were safe in my guns maybe not yours so use caution.

I've got a FiveSeven pistol and I'm wanting to start loading for it however I'm stuck in Dutch Harbor most of the year and local supplies of powder seem to be somewhat limited. Has anyone done any loading with Winchester 748, or 296? I've used 296 in my .357 with great results, just wondering if it's appropriate for the 5.7. The only other powder I could find that sounded like it might work is IMR 3031. I have a spread of bullets from 35-50gr, not looking to really max it out, just get some good solid performance for targets and fox to people sized game. Any suggestions for starting points on loads would be very helpful.

I have not. I use True Blue exclusively for this load. Both of those are slower burning powders and you will probably have to work up some loads. I think that you will have beter luck with the 296 than the 748.

Search the web and you may have the data that you are looking for.

FN 5.7 powder

I use the win 296 in a lot of my loads but did not try it in my 57. I have a hornet that loves the stuff and its cartrgae is only .039 cubic volume more than the 5.7 but i went with true blue instead. started at 4.2 and 4.7 next will be 4.9 and I will probably hold there. it will be the 4th round on the casses. I trimed them all to 1.130 and seated them to 1.589 using nosler 40 gn bal tip and serria 40gn hpbt. Im want to get my hands on a couple of the trident elite t6 brass prjectiles (hollow points on crack). Good luck and stay safe
