I have used this round in Ruger and Remington rifles as well as surplus military rifles specifically 1903 and 1903-A3 rifles as well as M-1917 Enfield rifles. I have used this round in M-1 Garand rifles. Results have been superlative.
Whitetail deer are not heavily boned. Even a large buck will seldom weigh more than 200 lbs. in the southeastern United States. I have used bullets in weights from 150 to 180 grains. I've settled on the 150 and just about ideal. I've not ever had a problem with inadequate penetration using a Remington or Winchester 150 gr. .30-06 load. In fact, I've not ever recovered a bullet as it always goes in one side of the deer and out the other side.
The last deer I shot was hit just in front of the left hip. The bullet rakes up through the deer and exited out the right front shoulder. The bullet was a plain Jane Remington 150 gr. Pointed Soft-Point (PSP). The distance was 181 paces using a Smith Corona 1903-A3 rifle with the standard iron sights.
I guess that it helps to know deer anatomy if one is going to hunt them.
