Yep, to follow up.
I loaded groups of 5.
Unique under a 95 gr. FMJRN
Up from 3.2 to in 2 gr. intervals up to 4.2.
Everything starting with 3.4 cycled the pistol.
The sweet spot for accuracy with the FMJRN was in the 3.6 to 3.8 range.
Everything on paper at 25 yards.
Except the couple I shot at 3.2 which didn't cycle , I guess they made the backstop all right but I wasn't on my 25 yard slow fire target .
So that settles that hash.
The surprise of the evening was in shooting some 100gr plated Berrys , over 3.6 gr of BE86 at .974 OAL. I had loaded that up for an import Makarov I own thats chambered in .380.
The Pico Pistoletta was grouping with the plated rounds and the BE 86, so that might be my practice round right there.
I stopped loading that round when I found that 3 gr of Unique got the Makarov shooting well, although in fact I think I could bump that up to 3.4 and get a bit better performance.
I also was shooting my CZ 83 this evening and with 3gr of Unique that pistol with stay in the black at 25 yards all night if you stick with a jacketed projectile.
Very glad for the performance of the Pico with the BE86 and the plated projectiles.
Cheers
