I can seat these out a lot longer in my Grendel and was wondering about a starting load with these. I am using a m16 bolt carrier and A2 buffer and tube with an 18" barrel on my rifle. I will be using IMI brass with CCI #34 primers. Since I have never tried any sub-sonic loads before I thought I would ask here if the loads you worked up with the .268 bullets would be ok to start with in my rifle.
Thanks,

My loads were with the .264 bullets. With subs you need to work down. If you try to start low you risk getting a bullet stuck and trust me, you don't want that to happen. What powder are you thinking about using? I'm assuming your barrel is a mid length gas system so you may benefit from a slightly faster powder than what I'm using (8208). I believe Rapier was using a 18" so his data may be a good starting point.
