"Dropped into S&W 40C a bit tightly. Constant failure to feed with Sellier & Bellot 140g FMJ. Fed reliably with Remington 125g JHP (green box ammo), but groups were ~ 5\" at 10 yds. Rounds did hit same point of impact as point of aim. Original .40 barrel gives better groups, but will try more 357 ammo depending on availability."
