    I’m getting a lot of failure to feed issues with my Glock 34 with my reloaded ammo. Factory ammo works fine.

    Glock 34.5 mostly stock, except for an aftermarket trigger and trigger spring

    Glock 19.4 stock

    Powder Winchester 231

    Powder weight 3.4 gr

    Bullets: Berry’s 147 gr round nose

    Overall length: 1.153

    Cases: Used Blazer Brass

    They seem to run fine through my Glock 19, but people say the cases aren’t flying out when ejected.

    According this site: [](

    Manufacturer Powder Bullet Diam. C.O.L Grs. Vel. (ft/s) Pressure Grs. Vel. (ft/s) Pressure

    Winchester 231 0.355 1.100 3.0 755 30,100 PSI 3.4 845 34,300 PSI

    I’m not much of a 9mm guy, but is it pretty standard that you’ve added 53 thousandths to the COAL? If your 34 has a chamber with tighter tolerance/non-worn (not as broken in as the 19) feed ramp, that could be an issue. Also with not seating the pill as deep, you are losing case pressure. But again, that’s just my observation from general reloading knowledge, not specific to 9mm.

    Do you happen to have a manual? I experiment with loads myself but, because of a number of factors, reloading can’t be half assed, know what I mean?

    Is it short stroking because of weak ammo? My gen 4 and gen 5 wouldn’t shoot anything other than full power reliably without a spring change. Check your scale with a check weight and use a chronograph to verify.

    Western powders (Accurate) does give data for Berry’s bullets, but unfortunately, they don’t list the 147gr RN. They do list the 124gr RN at 1.160″ COL. The Rainier 147gr PRN is listed at 1.160, too, but I don’t know if it’s identical to the Berry’s product.
