Well I tested out the 130 JLK bullets and my barrel doesn't like them. Had a node at 48.5 - 49.4 grains that looked promising, SD went down to 4 fps at 49 gr. with 10 fps SD at each end of the node. The groups were not great .750" to 1" 5 shots at 100, the 49 gr being the smallest group, POI was the same from 48.5 - 49.4 gr. I was .020" off lands so I loaded 5 each at 49 and 48.8 gr at .010" and .030" and tried them to see if they would tighten up, would get 3 to 4 out of the group almost through same hole and then 1 or 2 scattered. 48.2 liked it closer and 49 liked it farther away. I will do one more test .040" from lands and Jamming the lands, we will see. I also shot my 143 ELD-X bullets just to see if they were still good and 5 shots gave me one ragged hole, so I figure it must be It just doesn't like JLKs, I measured the diameter of the JLKs and the Hornadys, the JLKs were .2639" and the Hornadys are .2642" .
It could be I have an oversize bore and the larger diameter bullet shoots better, I questioned that when using H4350 because my loads were much slower than most everyone else that used H4350.
Not slamming JLK bullets they are very consistent in weight and length, but they do not work for what I want.
