A while back in another thread you asked about HP-38 & 231 being identical in response to my comment about H110 & 296 being the same. Its been hang'n around in the back of my head (the voices have been toss'n it around
) ever since. I kept check'n those powders every time I looked thru one of my manuals & I always found slight differences between those powders. Then tonight the light came on, one of the voices said "Hey Dumbass why don't you check the Hodgdon manual?". So I did & Hallelujah there it was, Hodgdon lists HP-38 & 231, H110 & 296 Identical in charge weight, Velocity & CUP. I'm still at a loss as to why the other manuals list them differently. Its late passed Mattie's bed time, so I'll have to let the voices work on this one a little more.
