6mm wsm or stw or other varient
I've got a buddy who wants to launch a 6mm or 6.5 mm 100 grain at 3800~4000 fps. I've been looking for wildcats and factory rounds. I have just now been able to get back on this site for some reason windows decided it needed a break from this site I guess. So my question is what are your thoughts? He wants it for varmint shooting and wants it either in 6mm or 6.5 mm so no 30 cals or anything under 6mm please.
Thanks in advance.
