I didn’t put this in the reloading forum because it deals with a Ron Williams DI45 upper. I was hoping it reaches someone who has past experance with this.
Last week I fired it for the first time. I have been trying to develop a load with 230 grain cast bullets that will cycle reliable. The first try, with 4.0 grains of Bullseye reloads, didn’t work out so well. The first round chambered ok when hand cycled, would fire, but not eject. With factory Winchester White Box the upper runs like a sewing machine. I tried again today with 4.5 grains of Bullseye. This time it would eject but the bolt will not pick up the next round in the mag. I think it isn’t running the bolt all the way back. If I hadn’t tried it with factory ammo, I would have thought it was a mag issue. Gonna load some hotter loads and see what happened. Can someone who handloads for one of these uppers share their pet load? Thanks |

I run 6g of unique behind a 230g montana gold bullet in my personal 10.5" upper. If you want to run lighter loads try a reduced power spring(or cut a few coils off a spare) & take the weights out of the buffer. Just be carefull not to forget there in there. Yesterday I tired a load of 5.0 grains of bullsye with a Magnus 230 grain lead round nose. I had lots of failures. Got maybe 8 - 9 rounds to run in a row then it would jam. FTF mostly. Again..If I hadn't had such good luck with factory 230 jacketed, I'd swear I had mag issues. Going to load some of the Unique and see how that runs. Is that a cast or jacketed bullet? thanks |

I run 230gr LRN and FMJ over 6gr unique. Stock buffer and spring on a M16 lower. Runs great all the time. Thanks, Ron!
