RE: poor blood trails, switch gun/ammo?
The pin hole 3006 does that sometimes.... If your shots are less then 200 yards all the time... play with the 870. I have an H&R Ultra slug 12 gauge and I kill deer ever year out to 200 yards with the Hornady SST's 300 grain. Bring a range finder and zero the gun for 150 yards with a gun vice. If you are staying in the 150 yard range and sometimes at 200 you will never pick up the 30-06 AGAIN with an H&R (its a 350 dollar package with a scope). My H&R poors blood on everything...big holes make for big blood trails....
But- - The 30-06...Is an all around master of disaster....its that darn narrow bullet the leaves us wondering sometimes....I've seen moose flip with a 30-06 though...the joys of hunting and learning...see your local dealer about an H&R....broaden your horizons...this forum has helped me learn alot from people like you....
