I've been thinking about trying WW231 in the 300 BLK. Yesterday I loaded 20 rounds with 231 and the NOE 247 cast using CCI 400 primers. Boolits were sized @ .310" and loaded to an OAL of 2.260" with a very light crimp. Four 5 shot groups were fired @ 50 yards using a Ruger Ranch bolt gun.
Results as follows: 4.3 gr = .837"
4.6 gr= .908"
4.9 gr= .598" (with 4 in .115")
5.2 gr= .682"
I'll do some further testing before trying the loads with the suppressor attached.Attachment 198436
