I was using a .30-06 with 150 gr Accubond at around 2850 fps from my 20" barrel carbine.
On body length shots like this, ya think a heavier bullet would have been better?
Yes. A 180gr bullet provides more reliable performance in the 30-06 than a 150 of like construction. However, I don't think your deer would have died any sooner regardless which bullet you use. Your shot destroyed vascular plumbing which is
eventually fatal, but not usually instantly fatal. If you want them to die more quickly, or drop at the shot, you have to damage the CNS or skeletal structure, or both. Next time try aiming for the white spot under the chin. Hit there, they tend to travel about 2 feet - straight down.
