Unfortunately, My Sig Ultra is misbehaving.
I seems to run fine with FMJs and Wilson Combat Mags.
But FTF badly on Federal HST and Winchester Ranger T JHPs
I've run 200 FMJs and 100 JHPs with no joy with the HPs
I'll run 200 more FMJs soon, followed by an assortment of various 185/200/230 with Hornady and Remington JHPs.
Let's see if the gun is ammo sensitive ...
Novak sights, 25 lpi front/backstrap and stock grips all feels great and shoots POA/POI
Just need to find JHPs this gun likes
