Thread: Bullet speed?

Any ideas on a low recoil load for my boy to use on deer?i have some 125g sst pills here and 2206h powder ,running a suppressed 16in .308,thinking 35g would be a good start,just bush hunting Sika ,was looking for around 7.62x39 speeds as a recoil table I have seen puts that caliber at the lower end and have used a mini 30 in the past and it always killed well. Thanks
