This seemed off to me and I can't figure out why . I am loading heavy weight 190 gr.ranchdog bullets in my 686 nothing fast and fire breathing just for plinking to use them up . My first try with these was 4.5gr unique seated to near cylinder length in 38 spl cases . They shot fine real mild accuracy was acceptable and no keyholing at 25 yds . I move on up and try 5 gr unique this past weekend and they all key holed! Why ? It's a little faster load should be better for stability right ? Took it up a notch and loaded some up with 10 gr 2400 . All shot fine what gives with the 5 gr unique load ?
