Years ago, killed my first deer with a 7RM, 2nd with a 243/100 Partition. Both went about 30 yards, but horrible destruction with the Mag.

Later had a shot at around 200 yds using a 100 Sierra and it was a very cold morning. Hit a deer facing me and never found blood. Later found it was shooting low and I was in a tower blind, a raking shot. I hit it but it left. A few weeks later someone saw a deer limping, fitting the description. I lost faith. That was LONG ago. Since killed deer with 243 and 6BR both, 70 TNT - in both - Lung/neck shot. 95 Ballistic Tip on many in both. Worked great, even blew thru both shoulders exiting at 100 yds. Also using a 105 Amax via 6BR, at 400 yds, struggled about 20 yds.

So, I have complete faith in 6mm's. Shot Placement. Bullet choice. Put a good bullet thru vitals. That will = success.
