6mm 95gr partition

[velvetant]

email to Nosler
I have an older 244 Remington with a 1-12 twist, do you think the 95gr pt will stabilize or should I drop down to the 85gr pt?
Randy

Response I got
We don't make a 85gr. Partition



So I ask the question here, do you think the 95gr pt will stabilize?
And yes they do make an 85gr pt unless they plan on discontinuing it.

 

[RiverRider]

LOL. Looks like your correspondent realized his mistake and corrected it with little fanfare or clarification. At least the second response was not "And yes they do make an 85gr pt and you should try it if the 95gr does not work." But then again, that would have been funnier. Take our laughs where we can get 'em, no?

 

[DrMike]

They still list an 85 grain PT spitzer on the web site (http://www.nosler.com/partition). :grin:

 

[RiverRider]

If they're discontinuing the 85-grain, I am glad my rifle didn't like them. They usually only discontinue bullets my rifles like. I do wonder how they find out which bullets my rifles like. Okay, maybe they don't...but I'm STILL hoarding!

Wish I could help. My 1974 6mm Rem has a 1:9 twist, and stabilizes the 100's and 105's just fine. That said, my favorite deer bullet for that rifle is the 95 gr Ballistic Tip. Accurate & lethal and has punched right on through mule deer. Great little bullet!

I just don't know if you'd need to drop down below the 95's for good results from the slow twist .244 barrel...

[velvetant]

I only got one response and that was "We don't make a 85gr. Partition"


The other comment is me asking the Nosler forum members a question.
I just want to know if you guys think the 95gr NPT would stabilize in a 1-12 twist?
And I don't think the bullet is being discontinued.

 

[SJB358]

I think it might be worth loading a couple with Nosler's most accurate load and trying it Randy.. If it groups, you could call it a day. I might have 20-40 of them, if you want, I might be able to send them to you to try..

They might work just fine though.

I thought about the 95 NBT but I know they are a long bullet and most likely won't work.

I just looked at the Nosler manual and I don't have any powders they used.
All I have is H4350 and H4831sc.

Agree, probably wouldn't work out. I don't have any 95 gr Partitions, do have a few very old 85 gr Partitions, maybe 20 or 30, leftover from loading those back in the (ahem) 1970's...

Although I prefer the 100 gr PT in both the 243-6mm , in your case I would drop to the 85 and not have any worries on deer sized game. Once again I would have a serious look at Hy brid -100 as a powder , it really shines in the 243/6mm .

I am with the others though. I am betting the 85's would be pretty fearsome on deer. Need a water jug test outta them.... :grin:

I got a wild hair the other day and dug out an old box of 85gr Partitions (price tag read $16.95, giving some clue to the age) and loaded up a few over H4895 for my 243Win Browning BAR. Tested them at the range and other than a single flyer out for all groups (seating depth!) I got two within half an inch and one just over an inch for all charges. I did not have my chronograph with me (which I hate, but it was a crazy range trip at the last minute where I forgot my front rest and my chrono, but remembered my tripod!) so no velocity, yet, but everything felt fine and the rounds cycled and ejected consistently to the same place the 100gr Factory ammo I've been shooting ejects. If I can get out with the chronograph just to verify, and shorten them up a smidge to see about pulling in the flyer, I'd like to hunt this rifle with handloads this fall instead of factory ammo. I will post any results I get from these 85gr Partitions on northern Alabama white-tails.

From the looks of the load data, I'd go for either powder you have on hand and load away. Nothing shabby about 3200+ from an 85gr Partition on deer, I suspect. I should be getting around 3100-3150, I'm guessing, though with an autoloader, I will lose some to gas bleedoff for cycling. I may be able to push my H4895 loads a bit higher, but I was being conservative on this workup.

I wouldn't be surprised if that slow twist will stabilize the 95gr PT. It's profile isnt that long. I would think it to be on the edge as history has proven that bullets >100gr are not stabilized consistently from that barrel.

If they do stabilize that load would be an excellent medium-sized game round at velocities +3k fps. Good Luck!!

Nosler also makes a 90gr BT. The BTs are technically longer than the Partitions (90gr BT OAL is 1.071" where the 100gr Partition is 1.065"), but the plastic tip is about .015-.018" of the BT length, and that's factored back out for stability purposes. According to my stability calculator, nothing over .969" will for sure stabilize, but stuff in the range of .97-1.061" may stabilize. Longer than 1.061" and it's not likely to stabilize at all. What this tells me is that the 95gr Partition might stabilize, but it might not. It's not likely the 100gr will stabilize at all. The 85gr Partition will stabilize. Due to the plastic tip length not being counted in the real stabilization length, both the 90 and 95gr BTs might stabilize in the 12 twist, if you get lucky and get enough velocity to marginally stabilize it out to a hundred or maybe 200yds. I'd sure shoot at distances before taking these hunting, to be sure they're going to fly straight.

The safe bet is to use the 85gr and go from there.

There are days I should wear gloves like these...

 

[velvetant]

Thanks all for your help.
Thanks for the load info Scotty

 

[JD338]

I think the 95 gr PT will work in a 1:12 twist. Nosler still offers the 85 gr PT

[velvetant]

I got some bullets from a gentleman on this forum, Thanks again very much for them..
Shot them today over a midrange charge of H4831SC and they produced a nice round 1.250" 5 shot group.
So I was concerned over nothing, they worked fine.
Will pick up a box or two and do some load work up.

 

[SJB358]

Nice! Those will be killers for sure!
