I voted 150 gr. because except for my .30-30, the 150 gr. Nosler Accubond is my #1, .30 cal. hunting bullet. Even though other weights will kill deer just as dead. In my 300 WSM, it's been used on pronghorns, mule deer and whitetails. Have also witnessed it take a mule deer at long range from a 300 RUM. Bullet performance was excellent every time. In my 300 WSM it displays great accuracy, which is why I began using it in the first place. I wasn't worried about the bullet construction as much as I was concerned about putting that bullet where I wanted it to go. There's plenty of other bullets that work, but I settled on one handload in order to be totally familiar with the trajectory and performance of that rifle with that load. Same deal with the .30-30; one bullet and one load, a Hornady 170 gr. flat point because with a suitable dose of Leverevolution powder behind it, it's my most accurate .30-30 load. The 30-30 gets used where I can't even see 100 yards in any direction, so the old school flat points work great. Tried the Hornady FTX flex tip, pointed bullets, but never got quite as good accuracy as the old flat points. Couldn't vote for 170 anyway, as there was no 170 gr. option. I have two other hunting uses for .30 cal. 150 gr. Accubonds; one of which is with a 5 round clip, in order to be hunting legal in my M-1 Garand. Only been out a few times and no shots offered yet, but someday I'd love to take a deer with it in honor of one of my late uncles, who carried an M-1 in the Pacific theater in the latter part of WW2. He thought my M-1 would make a great deer gun, because it's in .30-06, right? Just substituted some 150 gr. Accubonds for the 150 gr. FMJ's in my NRA High Power competition load, accuracy tested them, put 'em in a 5 round clip and it's good to go.
. That gave me the idea to try the 150 gr. Accubonds in the .308 chambered M1A that I also shot a lot of NRA High Power matches with back in the 1990's, early 2000's. They shoot great in that also, so this year it will get taken out for the first time deer hunting to sit in a blind on my buddies land. Got a 5 round mag for that as well. Always wanted to deer hunt with something like an M-14 ever since a bunch of us 18-19 year old kids were being taught marksmanship with the U.S. Rifle, M-14, by our Uncle Sam. For a lot of us it was enlightening to realize that we could hit things with a .308, (AKA 7.62 NATO), a lot further away than most of us, including me, realized. Then some guys began saying how cool it would be to hunt with these things. Funny how I never got around to it, but that should change this year.
. In .30 cal., for deer, I just couldn't vote any other bullet weight other than my favorite 150 gr. (unless it's for the .30-30).
