Sounds like a good combo! I hunted with a guy one year in SE Texas who had a Mod 742 carbine, also in 30.06. The blast and flame were terrible! I was trying to help him get it zeroed at 100 and he did good to keep them in a 8" paper plate. I tried to get him to settle down and do better, but, he wouldn't do it. He was too proud to admit the thing bothered him. Oh yea, this was w/o hearing protection too! I knew I never wanted a short barreled 30.06, ever, ha. I think you are on the right track, making it shootable. I bet that 165 cast load would ruin any zombies day also! Congrats on the doe!
