140 NBT vs 140 Accubond

I have been getting good results (accuracy/speed) from the 140 BT in 7wsm and was wondering how the 140 accubond behaves comparitivly.

With all the talk of bullet frangibilty with the NBT at WSM speeds approaching 3300 I have just switched to the accubond without ever using the NBT on game!

Any speed differences at same load or POI difference?

Just wondering what to expect.

Re: 140 NBT vs 140 Accubond

I have only compaired the 150gr ballistic tips and 150gr accubonds out of a 30-06Ai and they shot to roughlythe same POI the accubonds went about 1" higher in the groups but they grouped very well with the exact same load data as was used with the Ballistic tips.
Some guys say that they foul a little more than the BT's but I haven't noticed in a 3 groove Lilja

Re: 140 NBT vs 140 Accubond

Point of impact and accuracy are identical in my model 70 . NBT works fine on lightly built game in my experience . Haven't noticed that the 140 accubond is noticeably better so far . Accubond won't give full penetration on chest shot feral donkeys which weigh perhaps 500lb . Maybe the 160gn would be a better choice for serious penetration ?

Re: 140 NBT vs 140 Accubond

I used to shoot 140 SGK with excellent accuracy. The problem was, even on broadside shots, I seldom had pass throughs on whitetails. A friend of mine said they seemed to act like the BT's his 7mm shot. EXPLOSIVE!!! I wanted the ability to shoot a deer head on or through the shoulders if that was my only shot opportunity, and I just did not feel comfortable. So I switched to the Accubonds. I have not looked back. These things are just as accurate as my SGKs, and those were accurate.

I should also mention that I shot a decent size doe (2 1/2 yrs old) this fall during a cull hunt. I shot her facing me. The bullet hit just to the inside of her right shoulder and passed all the way through. The bullet exited through the pelvic area!!! She was only about a 100yrds, but I was impressed. This is out of my .280 pushing the bullets at about 3000fps.

They expand good, and I have the penetration, so they're a winner in my book!

Re: 140 NBT vs 140 Accubond

No experience in the 7 but have used both BTs (150) and NABs (140) in 270 cal.

Both shoot awsome. Both do great work on deer. But at 3600 FPS MV I opted for the NAB as it has shown to always retain the core which would almost guarantee greater penetration over the Ballistic Tip.

For deer sized animals either one would serve equally well would be my guess....

Re: 140 NBT vs 140 Accubond

Just about the same point of impact and velocity in my 7mm Rem Mags. The NAB hit about 1/2" higher at 100 yds out of my rifle. Accuracy was very similar with both bullets - I'd give a slight advantage to the AB in my rifles over the BTs.

All in all you will see little difference in velocity, POI, and accuracy. The ABs will cause a little less meat damage around the wound channel based on my experiences with black bears and dall sheep.

Re: 140 NBT vs 140 Accubond

I also shoot a WSM (270WSM). I will not use BTips for hunting with my rifle but will shoot AccuBombs for all my hunting. They hold together better at the higher impact speeds seen at my shorter shooting ranges (when compared to some here). If I was dropping deer at 500 yards on a regular basis I would shoot BTips. I have had reliable performance on deers and hogs out to my longest thus far (225yards hog) Impact velocities range from 3200 down to just shy of 3000FPS (per my chrono and Pointblank). 140grain Accubond and max load of H1000.
