thanks for any input you can give me.
The 7mm STW is a high intensity round and I would recommend staying away from the lands not
If you want to extend the mag so you can shoot factory loaded 7 STW ammo that is fine, but stay with the SAMME
Free bore is your friend when it comes to velocity and holds the pressure down. It also does not
help accuracy like in some of the milder cartridges.
All of the new high pressure rounds (65,000 + PSI) have lots of free bore but are still very accurate.
You will find that the Berger's will be very accurate .080 to .100 thousandths off the lands and allow for high velocity (The reason for going to cartridges such as the STW).
This is just my opinion for what it is worth.
