    Just getting started on a friends Dillon 550. I got this receipe from Hodgdon's web site. It lists the COL at 1.169 starting at 4.9 gr with a max of 5.7.

    We are at 5.0 gr but the OAL is 1.148 - 1.155. BTW: my factory ammo is 1.148.

    Does this all sound good and safe? I plan to test it tonight. First in the G17 then full auto in a CA89K. My obvious concern is when I use the smg.

    Thanks!

    I'm surprised Hodgdon's web site suggests a 1.169" OAL, that's pretty long. I have measured factory 9mm ammo that was that long, but I usually load shorter.

    I assume you're using round nose???

    If your question is will the shorter OAL be a problem, I'd say no. You are still obliviously toward the low end of the suggested charges, so the shorter OAL should be fine.

    So I'd say, it looks good, but you should probably just load a few test rounds in case they don't work you won't have to pull a bunch of them.

    XD: thank you. Yes they are round nose. I actually loaded 110 rounds and checked them all in a case gauge. I plan to fire 20 in the G17 then if all goes well I'll move to the smg - three 30 round mags on full auto go pretty quick.

    They also list 1.169 for a JHP with WSF. Very odd as that is really long for a JHP.

    I've never fired a full auto, maybe Steve knows, but do you think a low charge might cause jamming? If too low of a charge can cause problems in semi, then the uber fast cycling of a full auto might require at least a medium charge.
    So I would be very careful about loading too many just in case. Pulling rounds is no fun.

    It's likey a soft load w/ that long an OAL & a moderate powder charge. I would fire some single shot before committing to full auto. I run 5.1gr under a 115grRNFMJ @ 1.130", hits 1220fps+.

    Good advice! Even after testing in the G17 I do start on semi before going to the happy switch.

    Usually a higher vs lower ROF is preferred by the smg. I've been using Federal, American Eagle & Blazer 115 gr FMJ round nose and she eats everything I can throw her way. However if I try and run Fiocchi 115 gr FMJ's I will have 1-2 FTE's per mag. The Fiocchi is noticably hotter & these smg's usually run great on it.

    Range report: every round worked fine in the G17 and then full auto in the CA89K!

    Fred, you're getting 1220 FPS with a 9MM 115 grainer with 5.1 grains of WSF...?

    Congrats there, Kwesi. I thought I heard a loud sewing machine outside this evening.:supergrin:

    In regards to those rounds that you ran thru the smg, I'm curious how easily those casings can be reloaded. I have heard that casings fired in a smg (any caliber) are usually over expanded due to a typically larger chamber to promote functioning. How about giving us a report if you try to reload those cases.

    Hello:

    WSF and 9mm is a good combination. I use 5.3gr WSF with a Montana Gold 115gr round nose and get around 1,140 to 1,150 fps average in my CZ 85. I load my 9mms fairly long but check the OAL by first dropping them into the barrel and making sure they fall all the way in but don't touch the rifling. Then see if they fit in the mags and feed properly.

    Next visit I will separate the brass so I can report back. It's often easy to tell which brass was fired in the smg due to the flute marks.
