Went to the gun show a while back and bought a box of Nosler .270 160 gr. partitions. Does anybody here use this bullet in a 270 Winchester? I loaded up a few with IMR-4350 and they shot excellent in my Ruger MKII 270 winchester. I may take it on my Elk hunt next year for hunting in timber.
160 gr. partition in 270 Win.

That will be a deep penetrating bullet. Shoot one into some milk jugs and post a picture of the recovered bullet.
I am thinking it will go into 6-7 jugs.

Noslerfan: I,m acually working on the 160 PT as well. Same reason as you. Elk load in the timber. I,m playing around with IMR-4831 and H-4831sc. Will post results in a couple weeks. My bath room remodel job is interfering with my trigger time. Dang the luck. Not a lot guys use that bullet. Thats why no one is offering any info.

Thanks for the reply. I have to say the 160 gr Partition is the most accurate Partition bullet I have ever shot.For me,I'ts been hard to get my best groups with Partitions. Not to say they are not a great bullet, but just not as accurate as a BT or AB.I have 8 lb's of IMR-4350 powder so I'm going to go with it.

I have been using IMR 4350 powder in the .270 Winchester since the 1960's and have no complaints about accuracy and muzzle velocity with this powder. As far as the 160 Partitions go, I have limited use with testing them but have never shot anything with one. My usual load is 130 gr Partitions for my .270 Win for deer hunting. Nice to know that they are still accurate.

I just have to ask. Just how much accuracy is really needed for hunting a big game animal? I know it's nice to shoot tiny groups with your loudenboomerkickenharder but are they really necessary or in reality an ego trip. :shock:
I can't speak for anyone else but I've never carried a bench rest around on any of my big game hunts. :roll: I came to the conclusion that as long as the rifle I'm using will consistantaly shoot into 1.5" or less, then it's good to go. Do I have rifles that shoot tighter groups? Yes. Thankfully most of them do. Sadly one of my very favorite rifles does not. It took a bit over two years to get it to be a consistant 1.5" gun and lately with a bit if minor tinkering it's closer to 1.25" these days. The gun is also a one trick pony. It's a Ruger M77 tang safety RSI, the little Mannicher stocked model. I got into it cheap because the previous owner could not get it to group. It took two years playing with different powder and bullet weights before there was any success. What did finally work was a stiff charge of W760 and the 165 gr. Speer Hot Core. Velocity is not all that great according to those who prefer speed but at 2550 FPS it's more than adequate to at least 250 yards which is, so far, the longest shot I've had to take on a Mule Deer. So far, the record with that rifle is 15 deer with 15 shots. What's not to like?

I have to agree. For a hunting rifle 1 1/2 to 2 inch at 100 yards would be ok. In times past I would practice shooting a soccer ball size target at 100 yards off hand. When shooting like that it's very important how a rifle fit's. I'm just an average shot.There are other who did better than me shooting off hand. Simply stating that the .270 160 gr. nosler bullet seemed to be very accurate IMO.

A very interesting and true point Gentlemen.
My Grandfather says that in the 50's and early 60's you were lucky if you found factory ammo that would consistently group into 2" or less from lot to lot. And you felt plenty confident going hunting with that kind of accuracy too. Of course it is nice to have the bragging rights of seeing a nice tight 3 or 5 shot group from your favorite smoke pole but when it all boils down a rifle that will group into 1.5" or so is plenty accurate enough for big game hunting. Especially since the average range for shooting a deer is still 200 yards or less.
Mike Venturino wrote an article about this sometime back, about how the country had become a generation of group shooters. It was very interesting.
Shooting paper is fun. I am not knocking it and I shoot groups quite a bit when I go to the range. If youre a target shooter its a must. If youre a hunter it is fun yes, practical, not so much. Never if ever have I found a benchrest in the woods to shoot across when that muley buck walks into view on opening morning. :mrgreen:
Use the bench to sight in and select your load. Practice field shooting positions from then on out. They will be of more practical use for you.

So far I,ve always got under moa with 130,140 and 150 PT,s. I am anticapating the 160 will too. I also get even better accuracy with AB,s Bt,s. They are incredible accurate. Agree that 1.5 is good enough for general hunting. I do not have a rifle that won,t shoot under moa with PT,s. That includes a pair of .270,s, a 300 mag and a 30:06. Just me but I think bullets are made better than ever and deserve a lot of credit. :wink:

I'm curious has anyone else tried this bullet in a 270 Weatherby? It would be one heck of a good load for everything from deer to moose. Nosler's book says 3000-3100 fps is possible with this bullet.

RL 22 and H4831 are great powders for it. You should max out about 56 grains or so.
Nothing around here that bullet will not stop!

I'm sure there will be some 270 Win guys happy with that information Fotis 
I was checking the pricing of 270 Wby components compared to 7mm WSM and 7mm RM, quite a difference :shock: I can see whay so many guys reform their own cases from the 264 WM and 7mm RM.

If you know of a source of Reloader 26 I would love to hear about it. Its unobtanium around here. I have been using Norma MRP and am down to around 3lbs left and from what I can find out Norma powders will never be available again here in North America.
Hope the QL helps
Take care
