Home Forums Hunting & Shooting Hunting Rifles Accubond or Accubomb

Shot a buck this morning, 264 win mag, Nosler trophy grade loaded with 130 accubond.

Deer was 115 yards, broadside. he ran 150 yards, bullet was not found anywhere. We disected everything. Lungs were mush though.


Is this normal for this accubond?

Ok for some reason can't get the photo to load.

Looked like a very good hit. Some deer are just tougher than others. That one wasn't going to give it up.
Not a lot of experience with the AB's here but with the kind of velocity that one probably hit at, assuming that's an exit it doesn't look too scary.

Jmo, I have shot quite a few head of game with Accubonds.. Mostly 150, 165 in .30 cal.. and 225 in 338.. I have had excellent success with them.. Mostly perfectly expanded.. Can't locate a pic. right now.. None blew up.. Even a 150 gr out of a 300 Win. in to a large cow elk..

Buddy shot a 200 lb deer at 15 yards with his 300 RUM, 180 accubond 3200 Fps, in the shoulder the other day and he made it 75 yards. Bullet didn't exit and was in skin on the far shoulder. The shock busted his guts open and it was a disaster to field dress. Some times they are just going to run. I've found several accubonda in deer and they look just like the picture below. Only one time did a 140 accubond 7mm not exit or found in the deer. It also ran 150 yards. With all that's said, no they usually don't blow up in my experience of over 50 deer hogs and a few elk.

I've seen WT's, shot thru the chest with the 26 Nosler (140 NAB's/140 NPT's) @ 3,280 FPS, run a good ways. And, there was plenty of chest damage.

And, I've seen those same loads drop'em in their tracks. We try to stay away from bone when harvesting meat animals.

Velocity doesn't seem to guarantee DRT. It's helpful for long distance wind bucking, etc. "Speed kills" is a valid concept, just not 100% predictable.

DF

That's the entrance no exit. No remnants of bullets.

If that's the entrance, I bet you hit something just before contact.

That bullet was tumbling before it hit the deer...that looks like a crappy corelokt exit wound. The entrance wounds with accubonds I have used were neat little .338" holes.

That's what I think too. I've never had an accubond entrance look like that. Looks like a twig or something promoted expansion before impact.

Could the bullet have fragmented on the bone and actually blown some back out the entrance creating that gnarled mess?

Splash!

Well I an guarentee you that it didn't hit anything. 125 yards, wide open hay field. No twigs, sticks nothing.

I don't know but it never hit the shoulder bone, it hit just behind shoulder bone. Like I said we completely autopsied the deer trying to find the bullet.

Would it be tumbling, new model 70 feather weight 264 win, 1-9 barrel twist 130 grain bullet?

I should with a core lokt early in the week, just over 280 yards, it was hit mid way up just behind shoulder, it blew through, caliber size entrance, golf ball exit.

I am less than impressed.

I've killed close to 60 big game animals now with 140 or 160 AB's from a 7RM and 7-08 with outstanding results. That includes whitetails, mule deer, aoudad, and plains game in Africa. I think it's one of the finest hunting bullets available.

JG,

I agree with you about the NAB.

But, that's a nasty entrance wound, looks sorta like those early Ballistic Tips before Nosler changed the configuration.

JB wrote about some NAB's that slipped thru production with someone trying to hurry the process. The result was bullets not correctly bonded.

To the OP, are these new NAB's or some you've had for a while?

DF

This was loaded nosler trophy grade, from cabelas... just bought it tuesday

Agree Mr. DF.....I've never seen an AB do that, including a 140AB that connected with a big muley buck out of Big Al's 7STW at a whopping 30 yds. It retained 60% of it's weight.

I guess inexplicable things happen with bullets on occasion, but I have never experienced anything but positive results with NABs. Never recovered one.

That is not the entrance wound one would expect from a 130 gr. NAB, MV 3,100 fps.

DF

I agree guys, we have shot the 200 NAB out of the 325 wsm with proven results.

Could this be just a freak thing?

I plan on shooting something else with it soon and see.

My experiance

6.5X47L 130 AB @2850

Exit


Enter

I had a 140gr 7mm Accubond frag on an antelope. It was facing me at 100 yards and the bullet entered in front of the left shoulder and never penetrated the diaphragm. I just figured that the 3100 fps impact velocity was outside the design parameters.

My bullet of choice.

You guys saying your bullet of choice, have you tried anything else?

Shot a buck last week with a 200 AB out of a 300 why..3050 fps..deer was 40 yds... Punched clear through...couldn't even see an exit hole....feeling from the inside the exit hole was only slightly bigger than entry...buck didn't take a step..

Saw a guy shoot a smallish interior grizzly between the shoulder blades with the 200gr .325wsm factory load at about 125yds. Blew a hole about like a tennis ball in the hide there and apparently vaporized on the vertebrae it hit there. Didn't leave me impressed nor did the 140lb whitetail buck the same guy used the same rifle on that ended up with a 6" diameter exit on a broadside rib shot. He also blew a coyote nearly in half with the same rifle and load.

He likes it, puts stuff down right now normally with the blender effect in the ribcage. I'm a little more into penetration and less bloodshot. Heck the two bull caribou I shot last fall with 85gr Ballistic Tips out of my 257wby had less damage than anything I've seen him shoot with the 200AB.

Sometimes weird stuff happens.

son-in-law shot a doe antelope with a .30-06/165g TTSX, broadside at about 100 yards. Small diameter entrance but the exit side was open from the shoulder almost to the back leg. Multiple ribs were broken and entrails were hanging out. Not at all what we've come to expect from TTSX, which normally leave a small entrance and exit.

Sample of two 110gr NAB's from two different .270's on KY WT's. First was shot at approx 230 yards. Deer was DRT. Second was shot at 25-30 yards. Deer ran 30-40 yards. Both thru and thru. Both with smallish entrance and exits more like a TSX than a cup and core... But, two dead deer, so no complaints...

The entrance wound to the very first 140-grain .270 caliber TSX my wife fired into game (the very first year TSX’s appeared) was much bigger than the one that started this thread--and the animal was coyote at about 200 yards. Two days later Eileen shot a spike elk with the same load, at just about the same range, and the entrance wound was tiny.

Samples of one never prove anything, except that something happened once.

I've shot several deer with 140gr 7mm and 130gr 6.5mm accubonds. Never got consistent results with them. The ones that passed through left very small exit wounds. I had a couple that blew up on entrance that had about a 2 inch entrance and 22cal sized exits. Ballistic tips are more consistent on performance.

I've shot hogs and deer with the 110gr .257cal, 130gr .264cal, and 160gr .284cal versions. I always got consistent performance from them, although the .257 did not give me the penetration I wanted on several occasions. I shot it at 3,100fps or so. The others were launched at 2,800-2,900fps and are still my bullets of choice in several rifles.

That entrance looks like the holes I used to get with 175 partitions (3,150 fps) from a 7-.300 Weatherby with a 28" barrel. I never aimed at the shoulder. Also never recovered one.

Two 140gr Accubonds went all the way on a Mt Goat ar 20 yards. A couple of the same on Deer. One at 358. Small sample, but I would think there coming apart is the exception.

Well I am going to shoot one more with... It will be a purposeful shoulder shot. We shall see.

Some have said Accubonds are their bullet of choice. I concur. I've taken game using Accubonds across the spectrum from 6mm to 375 caliber.

Another asked have you shot any other bullet. Yes, Speer,Grand Slam, Trophy Bonded Bear Claw, Barnes X, Barnes X XLC Coated, TSX, TTSX, Berger, Hornady V-Max, SST, Interlock and Interbond, Sierra Game Kings in Spitzer and HPBT, Combined Technology Fail Safe, Ballistic SilverTip, Nosler Solid Base, Ballistic Tip, and Partition, to mention a few.

Most of the critters I've shot have been under 300 lbs and include hogs to numerous to count, bear, deer,exotics (axis, black buck, sika) javelina, varmints and Aoudad sheep. Consequently I can't speak to critters like elk. I've recovered one Accubond from a white-tail doe shot lenghtwise. It went through the front shoulder and lodged under the skin of the flank. All others have been through and through. Distances from 30 yds to +/- 400 yds. Velocities from a low as 2,400 FPS MV to +/- 3,200 FPS MV.

Typically a small entry wound..........



and an exit wound that while not overly dramatic (IMHO somewhat larger that that of a Nosler Partition or TSX) at similar distances and MVs.



The hoglet in the above pix was shot at a distance of 175 yds with a 200 grain 8mm Accubond started at +/- 2,800 FPS and is typical of the results I see.


JAPPFT,

This was my first thought as well. I am going to just stick to using NP's..

I have shot a total of 5-6 140 AB's into 3-4 decent sized deer and recovered the very first one today.


Bad shot on my part, quartering away hard(150-200 yards?), hurried, dropped him on the spot but required a broadside finisher 100 yards later(textbook dime in, golf ball out through a rib and little shoulder).

I wouldn't take a first shot like that unless I had confidence in the bullet.

The 140 Accubond in 270 is uber.




Found on the offside hide after ruining a bunch of good vension. Missed the mark by about 3" left.

This is a broadside exit on a bull elk from a 180 AB handload fired from a 308 at 2550 MV, 278 yard shot so a pretty mellow job for that bullet. Looks about the same as the exits with the 165 AB out of a 308 I've seen. Bull went maybe 75 feet and fell over.

Allen Day used some of those first Accubonds, and that is where I first heard the "Accubomb" moniker.

Maybe they had another bad batch???

This mirrors my experience with the 140 Accubond in the 270 win. I load them for my hunting buddy and have watched numerous elk, deer, and antelope succumb to that bullet without fail. I usually use the 130 Partition in my 270, but would roll the 140 bomb without hesitation.

It weighs 91 grains.

Kind of surprised at the OP's 130 gr AB performed they are usually very consistent. I guess weird things happen the odd time.

I'm a 270 Accubond fan. I bought a chit load of 130 gr SPS seconds a while back. I haven't taken any BIG game with them but I have shot sheep, black bear, and a ton of blacktails with'em. If a moose walked in front of me I wouldn't hesitate to pull the trigger though my 375 is usually with me when that might happen.

I'm about done with the 130s but bought another chit load of 140s recently and I'm sure they'll allow me to continue to eat well....

I switched to 140 gr. accubonds three years ago in my 7MM-08.
I have three one shot kills with them. None of the deer did more than spin a 360 and drop. While that is not an extended scientific test it does show some really practical results. I think it will be my bullet of choice again next year.

With biological specimens, critter, etc., linear engineering relationships don't apply.

Due to variables involving living tissue, data is basically a scattergram, not linear and is expressed as bell curves with deviations from the mean/probabilities, etc.

So these aberrant results represent what happens at the tail of the bell curve, greater deviation from the mean, but still under the curve and always possible.

I've been using the 140 AB in my 270 Win since 2006. Killed somewhere around 21-22 animals, mostly deer and elk. Ranges on recovered bullets were from 20 yards to 250ish.

They've always performed well in all categories for me-accuracy, internal damage, penetration, blood trails, etc... I was a staunch Partition user for many years prior to using AB's. Still think the PT is a dandy bullet and probably has an slight edge in penetration over the AB in equal weight bullets. The bullet on the far left is a 150 Partition, it retained 59% of its original weight.

I'm pretty sure I've recovered every one that has stayed in an animal. Which in a couple cases, it was pure dumb luck I found them.

I don't have lots of experience with the AB's yet, but based on accuracy and our results they have become one of my favorites. We have had very good results so far with the 6mm 90 gr. and .257 110 gr. bullets. Ranges have been from 100-255 yards and all bullets have exited if I remember correctly.

Enough with the science already.

Slow that same bullet down to 260 velocities and I think you'd have a dead deer with same shot in less than 30 yds.

If I wanted a 260 I would have bought one.

I'm fixing To do another test soon

Sheese! Makes me wish I'd have built a 270 this year instead of the 06. Not much to argue about with those results.

The only ABs I've been able to blow up were the .243 90s at 3600. No exits and only frags left. That's asking a bit much of a light pill. My brother runs them about 450fps slower in a 6 Rem and they perform quite nicely.

In quite a few various larger cals, they've performed like partitions for me from small animals to bull elk.

just fer schitz n' giggles.........



Best,

GWB

Funny that so many have wonderful pictures of recovered bullets and yet so many say they have all passed through. On a small sample across several calibers from 25 to 375 I have yet to see one escape the surly bonds of hide on the opposite side. Not one, ever.

I understand why so many good pictures of recovered Accubombs exist...

Oh, they would be about my last choice in bullets. I have even had SMKs and Core-Lokts up close pass through more often...
