Thread: 7x57 subsonic

Robert has a 120 grn hp cast that looks very similar to the awesome 151s in .308 that so many fellas swear by...that would be my starting point and using trailboss IM GUESSING somewhere between 10-12grns.....because 6-9 seems to be right in smaller cases...std primers,not magmum. and just let mate know to be cautious of bullet bounce it he misses and hits likes of rocks/concrete.....one thing for sure if one does go wrong he in much better position to end it without issue by putting noisy load in and whacking one in neck...not ideal but hell of a lot safer than trying it with .22lr.
