Mackillan, seems like you have taken quite an intrest in the 7mm calibers. The answer is yes they work well, and they are very accurate I have found in any caliber. I have 4 rifles in 7mm calibers which all are one type of magnum or the other.
I shoot 140 grain and 160 grain accubonds in 2 of the 4. Like I say accuracy of this bullet is great. Your barrel will tell you if its a 140 or a 160 grain slinger. I wish they made a 175 or a 168 but oh well.
I have infact harvested 3 deer and 2 bear with the accubonds and I have yet to recover a bullet and the second bear was through both shoulders. Out of all the bonded bullets its not 100% the best and does not hold alot of wieght retention from what i hear but, it has not let me down plus I have never got one back to see.
Some day I am going to shoot some old wet books to try for myself.
For 200 lbs animals its a great bullet.
