Most of my personal M2 Ball is Greek HXP non corrosive from the CMPicon. Shoots great and reloadable. The Korean rounds we shot in the Mauser was just the one box of PS and the handful of KA my friend had. He gave me another handful and a box to chronograph later. I’m a bit Leary of the KA as I’m hearing of kabooms with the KA headstamp. Any input on how safe it might be to shoot another five or ten to clock speeds would be welcome. I know that what we shot of the KA was definitely hot!
My shoulder could definitely tell the difference between the two batches.
