I tried them at 950 fps and they were not happy.... However, used at typical wadcutter velocities of under 700 fps you could have a totally different result.... I simply don't know....Bob
I never got the WC 250 mold but the 26 grain pellets I cast from the 250-27-RF mold are killer in the unchoked barrel on my DAR25 and they do shoot about like the JSB25.39 out of the Mrod with a GM barrel.
I have a .25 mrod on its way to me I need to get some parts for it to shot it but Id at least shoot some to see what it does.
Still grouping like a shotgun.
Somebody needs to try these under 700 fps, which is what wadcutters are designed for....Bob
