Monoflex ML - more powder???

[Handcannon]

I got some Hornady Monoflex ML 250s & shot a few this morning. They fly & group about the same as the Hornady SST 300s. I managed to recover 2 out of the gravel/dirt burm. One did expand a little, the other - not at all.

I'm shooting 2 pellets of T7 50/50. Should I go w/ 3 pellets to get these things to open up?

Real nice shooting, you can try 3 pellets, if the group opens up then go back to 2 pellets, or switch to BH 209.
