Hi all wanted to talk about my reloading of the 5.7 , shooting out of a PS90.
Some background on my reloading experience; been reloading 44mag ,45acp,38spl,308 and 243 for about 20yrs. with no problems at all.
I have a cronograph.
Now as to the 5.7 useing Western powder/Ramshot powder data obtained from FN Forum
True Blue powder start load 5.4 gr., 45gr Barnes Banded Solids.
OAL case length 1.35, CCI 400 sm.rifle primers
First 2 rds loaded at 5.4 gr. had flatened primers . Backed off to 5.2 grs (2275 FPS) one round fired and had a neck seperate and had to remove from chamber. Backed off again to 4.0grs. (1801fps) still slightly flat primers.
I decided to give up. I cant afford to damage any firearms that cost $1500. Reloading 5.7 is just too new for me. Hopefuly the ammo industury will develop loads with larger selection of bullets to choose from.
Until then for me its SS197SR.
Buy the way anyone want to buy aset of Lyman 5.7 three die set with shell holders for your press, Lee auto prime. Lee case lenght cutter holder. and 95rds Barnes 45gr bullets $105 shipped
