    I'm sure this has been discussed to death, BUT...

    I am currently loading 124 MG fmj and need to order more. I've read alot of posts that seem to favor 147's. I shoot a Glock 17 in USPSA production. Also, I use TG and 231 mostly. I just can't seem to find a load that beats factory for accuracy.

    Suggestions?

    People say the 147s have the least snappy recoil, but with 147 you load/powder choices are fewer and with some powders that work fine with the lighter bullets, you may not be able to make min PF (if that matters for you) with 147gr without going beyond max loads.

    What's the MG load? Have you tried a couple tenths more powder? I've found better accuracy came toward the higher velocities. Factory 124 or 147 gr loads chronoed about 145PF through an XD tactical. Don't have an info on MG but Zero 125RN got a 131PF in the XD and 127 in a G17, Precision Dealta 124FMJ got a 128PF and the G17 125. Testing done in Apr & May using 231 and accuracy was acceptable at 25 yards.

    I don't really understand your question. But I load 124gr MG bullets to 130PF. I have also used 147gr bullets in lead and FMJ to the same PF. They all work fine for me. 4.1 gr TG at that OAL should make PF nicely. Are you having accuracy issues?.

    Agree with C4W... I load 4.0 TG with a 124g PD or FMJ at 1.130 OAL makes 130 PF at 1050 fps with a SD of only 6 out of my G34.

    If your saying that your load is not as accurate, I would say check your crimp as I have seen that that 231 / 124g FMJ load to be very impressively accurate first hand. I have a fellow shooter at our local club that uses that load combo at 1.130 OAL.

    He is a good shooter and has very good results with that load, so much so as I had to ask him when I watched him shoot a couple of stages.

    I use 147 LFP to keep the cost down for plinking but have personally decided to stick with MG 124 by the case unless really good deals on other types come along.

    My crimp is as tight as I can make it WITHOUT making a ring around the bullet (when removed to check).

    Maybe I just need to wait for warmer weather. It's 25 here and the best I can manage is 4 1/2" @ 15 yds off hand (10 shots). I was hoping for @ 3".

    That may be too much crimp. In 9mm, you don't really want crimp...you just want to remove the flare you did to ease seating the bullet.

    Measure one of your bullets. Measure the wall thickness of the neck your brass. A loaded round at the neck should measure the bullet diameter + 2x brass thickness. If it's smaller, you probably have too much crimp.

    This could be true... even with leaving no mark you still could have TOO much crimp.

    I agree that measuring is the most definative way of assuring the actual crimp, though can be difficult with the 9mm taper cases. Additionally, I disagree with the "No" crimp theory setting my crimping dies to average .375-.377 inch, this range accomdates for different thicknesses of mixed brass.

    you need to do something like this.

    Montana gold 124 gr Power Pistol OAL 1.12


    Gains velocity Group size
    5.2 1024 1.45
    5.4 1056 1.0
    5.6 1075 .98
    5.8 1056 .95
    6.0 1024 .79

    All it takes it a little time and a crono.
