Gray fox,
Im not sure of the specific chamber. Ive tried 120/123 eld-ms, 123SSTs, 123smks 130RDFs and 120TTSXs with TAC, Leverevolution, 8208xbr and blc2. IÂve gotten nice 5 shot single digit SDÂs with 123 grainers.
IÂll work up a load in .3g/.4g increments and shoot until I see pressure which seems to be ejector marks with the Grendel more so than super flat primers. Ill generally find at least one node and reload zoomed in that area. The problem is Ill get to the range with loads in the sweet spot and they shot terribly as if IÂm using a different batch/lot of everything which makes me want to pull my hair out.
Example: in the link below I had a good 120 Eldm load from a previous work up. The two upper left groups I shot to confirm came out like hot garbage. Also, in the new work with 123sstÂs one would assume I found a node between 27.7 and 28.1 right? Similar tight grouping and POI. Next time out I shot in that range in .1g increments and all loads in that rang were junk.....averaging 1.25Â. This doesnÂt make sense and for what itÂs worth the bottom 4 groups are store bought 123ELDmÂs
