Partitions OR accubond

[Richracer1]

Truth be told, you can't go wrong with either bullet. The only Partition I've loaded up and shot game with was the 160PT out of my 270WSM. This was just before the 270 140AB came out. Since then I've stuck with the ABs and they haven't let me down. Now, if I couldn't get an AB to shoot the groups I want, the Partition would be then next bullet I would try.

Another 1/2 inch and it would of.
I'll go ahead and put another 1/2 grain of powder in the next batch I load up bullet, just for you!

That is to cool Antelope Sniper another 1/2 grain for me, I like it, good response. :lol: :lol:

Richracer1, I agree, they both work as I have said before. I am glad there is a choice and if you can't get the one you like the other one will do.

the unlimited velocity may be stated but at high velocity impacts on high resistance targets (shoulder hits) if the Partition inside the Partition bullet ruptures, penatration stops immediately.
I know a smith who necks down and improves a 338 RUM to 257 cal. he tested the 120 gr partitions in this cartridge.
fired into a gallon jug of water at 500 yards, more often than not the H-mantle ruptured and didn't exit the jug. he was shooting around 3800 fps MV.
The accubonds may become a mangled mess of copper and lead but it stays togather and keeps penatrating.
I've taken 17 deer in the last 3 years with the 160 AccuBond, I send them downrange at 3550 fps , and the deer have been taken from 307 to 1350 yards, Only 1 failed to exit, that deer was shot hard quartering away at 450 yards, the bullet hit an unseen limb, entrance was tennis ball sized, the lungs were peppered with shrapnel, and found a sliver of copper and that was it, I guess the bullet was lost during field dressing.
for normal velocities, shoot whichever your rifle likes, for high velocity impacts I'll stick with the AccuBond.

No way the AccuBond if it flattens out into a mess and has lost a lot of it's mass, it does not have the momentum to continue to penetrate because it can't. I have had a 165gr AccuBond out of my 300Win Mag hit a buck in the shoulder at 87yrds and it started to run up the neck but stopped due to the fact there was not much of it left and it looked like a little pancake. If you don't have enough mass for the velocity at hand it can not penetrate because it does not have momentum. It is momentum that allows for penetration not energy. You can have very high velocities but if you do not have sufficient mass you do not have sufficient momentum for penetration. No way can a AccuBond flatten out and mangled, penetrate like the Partition, because the front area created by the expanding bullet will slow and does limit penetration. They are two great bullets for what they are intended for but I would choose the Partition any day of the week over the AccuBond for serious, up close or dangerous work as well as excellent down range performance both in flight and terminal ballistic results. Experience in the field is why I choose the Partition over the AccuBond.

Thats your choice, glad you have it. But I'll stick with what works the best at the velocities I run. 300 winny velocities are a 300 yard impact for the stuff I shoot. If you ever have a rifle shooting a cartridge at the velocity that will rupture the H-Mantle you'll see a Partition turned inside out, accubonds just handle high velocity impacts better.
Like I said I've had 16 exits from 17 deer, thats just with the 160's, have taken a few with the 110 gr .257 AB as well.
I know that the smith who tested the partitions at high velocity isn't lying, and if I ever am faced with a shot from my high energy magnums on a 40-75 yard whitetail, you can bet I'll have an AccuBond in the chamber. I have just a bit of experience at this also, it ain't my first rodeo!

Well I am not going to argue with you because my exits on deer or over 200 in 38 years (some helping MS game wardens on reducing population of deer) on deer alone using BT, Accubonds, Partitions and Game King 165gr HPBT. This is not counting hog, black bear, mule deer and elk, plains game and lion in Africa. Now I just simply don't agree with you and deer are really not an animal that will test a bullet. I have use 257Wby, 257-300Wby, 416Wby, 458Win, 338Win, 35 Whelen, 300Wby, 444Marlin, 45-70, 22-250, 25-06, 270, 260, 30-30,7mmRem mag, 7mmSTW, 30-06, 308 just to name a few cartridges I have used for hunting through the years and taken game. Now I will say it one more time and that is they are both good bullets, but I have seen the Partition and AccuBond on same type of game and the Partition in my fast cartridges above are superior on a consistent bases and I am not talking about the exception to the rule when you have a small select sampling like you are discussing. This is not personal, I just don't agree with you and I am sure you will continue to use the AccuBond which is a good choice. My comment was that the Partition over a board selection of game from different rifles prove overall to be more consistent in my experience which I have been able to witness.

well, just by reading your post I can see your of the "my dog is bigger than your dog " attitude and I'm not in the mood to do battle with someone who is poorly armed, so I'm done with this topic, and I stick with what I've posted, With any common sense anyone who knows the makeup of both bullets can figure out which survives high velocity impacts the best.
like I stated before, they both perform just about the same at normal velocities, but the AccuBond with its 1 piece core bonded to the jacket will hold up better due to the facts that 1) there is no H-mantle to rupture at high velocity and 2) the bonded 1 piece core doesn't work against itself when put under alot of stress
By this I mean the harder rear core is trying to drive itself through the H-Mantle and the softer front core while it is expanding and shedding weight. its just common sense that while its an excellant bullet thats proved itself for years, if you hit something with enough resistance, at high enough velocity it will come apart. 40 years ago it could take whatever was dished out but with improvements in propellants and larger capacity smaller bore cartridges thats just not the case anymore.
and whats 200 deer in 38 years got anything to do with this topic, I've taken over 150 with a 223 while cropping heards on damage permits, and I've been hunting longer also, like I said, it ain't my first rodeo.

Well don't take it personal and you do have some very valid points for consideration and with some cartridges you are probably right. Don't take offense and it is not about who has the biggest dog, just used hunting info to let you know I have also seen a few things. I hope your hunting and shooting experience will continue to be an exciting one and a success. I am sure with the AccuBond it will be and your experience and skill it will be. Yours truly bullet

What do they call that 338 RUM necked down to 257 :shock: and how fast does it go? :grin:

Voted for the Partition, simply because I've never gotten around to using the "new" AccuBond. First started using Nosler Partitions somewhere around 1974 or 1975 and they've served me well.

I suspect there's a place for the AccuBond too... :grin:

Greg, its called a 257 Allen Mag, the quote I have from the developer of the cartridge states from a 30" barrel it runs a 115 gr NBT at 3800 fps, with groups in the .3"s and a barrel life of 1000-1200 rounds if you use ball powders, actualy to be safe ball powders are strongly reccomended in the 257 AM.RR

 

[Antelope_Sniper]

I've broke 3800 with 120gr BT's in the STW. I just like my barrel too much to shoot that load very much.

 

[Ridge_Runner]

I've ran 160's at 3706 fps in the 7mm AM, and 3350 with 200's, but you just don't need that kind of velocity with those weights.
the maker of the 257 AM (Kirby Allen) highly recomends the 156 gr wildcat in that cartridge, at 3300 fps it shoots flatter than the 338 kahn with a 300 gr at 3050 fps to 1500 yards, the difference in total drop is 112"

I used alot more Ballistic tips and AccuBonds than Partitions, largely because that is what was on sale at the SPS and I find it easier to get uniform COL with poly tipped bullets. It's more than than likely laziness on my part to not get a compartator and know for sure.

I have some NPT 140 grns loaded up at home, bout 20 rounds. I'll have to send them to my uncle as I traded off my 264 win and they won't chamber in my 264 Pacnor becasue the necks are not turned. I wouldn't say one is better than the other ( NAB or NPT ), it's all application.

The AccuBond does what I need it too, meat damage is whatever it is, but if that's an issue I'll go for the white patch on the throat and it's not an issue.

Barrels won't last long on some of the hot rod cartridges out there. My 257-300Wby was pushing a 100gr TSX at 3978fps and my barrel did not last quit 500 rounds. We were not sure exactly when it gave up the ghost but at 400 the throat was still in fair shape but somewhere between there and 500 rounds she was toast. That was an expensive build and experiment. Not going there again, to much trouble, time and money.

Nope, not going to get into this subject, I need to practice self control.

Thanks for all the replies for this hunting season I'll be using the Partitions I cant find any AccuBonds in stock for my 300 RUM.Also I e-mailed Federal to see if they had any plans of offering AccuBonds for the 300 RUM and they said NO They're not even thinking of adding anymore to the 300 RUM lineup just the 3 that they have 1 a 200 grain Nosler Partition,2 a 180 grain Barnes Triple Shock X bullet,and 3 a 180 grain Trophy Bonded Tip

Sounds like a reason to get into loading your own.
