Am I good to go with this load?

    I know this may be an adolesent question, unless you are new to reloading. Your input is appreciated.

    9mm
    115 gr RN FMJ
    4.1 gr Win 231
    Use: Skills practice on paper and steel
    Glock 17

    4.1 is the starting load recommended by the new Hornady book for Win 231 and 115gr FMJ. I loaded 15 to test and was satisfied the accuracy and had no troubles that I know of. Seemed to operate the slide just fine. I threw in a factory target round in the middle of the mag just to see if I noticed a difference, I did not. Is it ok to be on the low end of the recommendation? Anything else I should consider?
    Thanks, David

    If the load cycles the gun properly and meets your accuracy requirements I am not seeing a problem. Load up a few hundred and go shooting.

    I'd slowly work up the charge to about 4.5 grains of 231. That should still be on the light side.

    It's OK to stay on the low side as long as the pistol functions and accuracy is acceptable. But it's better to have a little buffer, because the gun may malfunction as it gets dirty.

    SC_Dave,

    As both of the other guys stated, if your load cycles your pistol and is acceptable to you in the accuracy department, than it's a keeper. :thumbsup:

    JBnTX touched on a point that is worth extra consideration. I have had an experience with minimum charge load once that got the bullet stuck in the barrel. Apparently one cartridge must have had a light charge and that put me at below minimum with not enough to push the bullet out the muzzle.

    You are most likely OK because you are using a lighter bullet (115g), if you were perhaps trying to push a 147g bullet - maybe... maybe not. :dunno:

    Moral of the story... always stay off the bottom, test a few grains higher just to stay on the safe side.

    That's my 2 cents

    Perhaps a few "tenths of grains higher" would be more prudent. :wavey:

    When you get to a chronograph, see how fast the bullets are moving. The velocity information in the manual is ALWAYS optimistic.

    Given the velocity, you can compute power factor (pf) as bullet weight in grains times velocity in feet per second. You then divide by 1000 before talking about it.

    You will like to get around 130 pf because the lower limit for competition is 125. BTW, Federal Champion BARELY makes it.

    130 pf for a 115 gr bullets requires 1130 fps. 125 would require 1086 fps. The extra 50 fps is just insurance for the possible variations that might occur at a match with a different chronograph.

    It's just a number to keep in mind. I try to get my loads somewhere above the minimum for the various classes even though I don't compete.

    Think I'll bump it up to 4.5 and see how that works. Thanks folks!

    Well, if it runs & is accurate for you, then you are done. You can always work it up further, see if things get better. I find starting loads are rarely the best in any firearm, any powder/bullet combo.

  11. I load 4.8g HP-38/W231 under my 115g Berry's. As long as your pistola cycles you're good to go, but 4.1 seems a bit light to me.

    Good idea. My G17 did not function well with your light load. Also follow manuals recommendations for OAL as you get past midrange loads as it to will impact pressures.

    My 4.1 loads with W231 are a bit too light for my G19...I would get a FTE 1 in 10 or 12 rounds. I'm going to try 4.2-4.3 and try to ease over the "hump".
     
  14. All 9 mm brass is rated for +P pressures. The only difference is the head stamp.

    The 4.1 with a 115 grn bullet does seem a bit light to me too. You may have cycle issues with some guns.
