Posted By: djb How tough is a .277 150 Partition? - 09/06/17
In a new Tikka I thought I had my hunting load figured out for the year. The 150 Partition shot well with 60g RL 26 at 3000fps, but the 130 TTSX shot crazy good at 100. I moved out to 200 yds today and had big surprise. The 150 Partitions bested the 130 TTSX. Weird how sometimes a 100 yd group doesn't always tell you what will happen further out. Great thing is both bullets (and 130 Ballistic tips) all shot to the same POI. Anyway...I seem to always get shots at elk under 100 yds and wonder if the 150 Partition will make a mess or have issues on close shots going that fast. I have had great results with the light TTSX's going fast but havn't ever taken an animal with the 150 Partition.
I've used Partitions at up to 3300 fps muzzle velocity and had no problems on shots under 100 yards. They do destroy more tissue than some other controlled-expansion bullets, but that's why they kill well.

Have found the 150-grain .270 to work fine on elk and moose, and also on antelope, whitetails, mule deer, caribou and various African plains game, including the notoriously tough gemsbok and blue wildebeest.
The Partition has been a standard to live up to for some time. It's the bullet I would pick for sure if it shot well. There's just not much it won't do well. Part of it will fracture for devastating chest-lung damage on broadside shots and you have a large portion that will stay together to penetrate if you happen to have a hard quartering shot or a mistake where a lot of penetration might save loosing the animal. You should get an exit either way,with max damage. Not much to say against it.
Great bullet in my 270 win results are always good use with confidence. They're soft up front and will do a lot of damage if you hit big bones.

Good luck and shoot straight

Tough enough to shoot completely thru a bull elk at 250yards broadside..Bull died just as quick as any I've shot with various 300 magnums and 30/06s!
folks, with regards to the performance on a Bull with a 270, this thread is really helping me. I have a cow hunt in Oct and I was going to use my 06 with a 165gr. NAB. I always take a backup rifle. My backup on this trip was going to be my (new to me) 338 WM. But now I thinking my 270 or one of my 6.5 sweeds.

I'm not an Elk expert but I would say take the one you shoot best and load it with a good bullet that it likes.
They will make one VERY dead elk!!
The 150 gr Nosler Partition is not perfect. But, if we are talking deer, elk and such it is very, very close to perfection. BTW so are the 160gr .284 and 180gr 308 Nosler Partitions. There may be others, those are the ones I have a lot of experience with.
Shot 2 elk last year with that combo - 270/150 NPT. Two dead elk. The broadside shots wouldn't stop the bullet even at close range. A shot into the brisket/neck did stop one of them. Perfect mushroom/NPT behavior. That combo will work fine.
Thanks everyone. I'm headed back to the range now to re-verify. What ever bullet shoots best today will be what I take. A cool thing with this Tikka is how the POI hasn't changed and I have used 4 different bulets. I guess I could literally run the TTSX for up close/still hunting and use the Partitions if a longer shot presented itself.

I used a 250 Accubond a few years back (9.3X62) and it really made a mess of one shoulder; the elk dropped like a sack too! I kind of switched to TTSX after that. Last year I took a young cow at about 50 yds with a 130 TTSX out of a 308. Velocity is just over 3000. It did great and I did find a broken off petal in a shoulder roast I cooked, but the shoulder wasn't ruined.
I have gone back to the 150 Partitions this year, now that I combined them with Reloder 26. I am getting 3040 fps from a 22 " barrel with my .270 win. If the fire season ever quits and we have an elk season, I will use it.

I wouldn't piss around with that BS. Pick one and stick with it. But YMMV.

Thanks. Yeah, I was being silly. I definately like simplicity.

Well, I shot two more groups at 200. The RL 26/150 Partitions shot a nice 7 shot 2.5 inch cluster with one flier about 2 inches out to the wind prevailing side. The wind was pretty gusty and I may have pulled it. 7 130 TTSX's went into about 3.5 inches. Formidilosus's recent posts about 10 shots groups really make sense as to realistic accuracy. There were may 3 shot clusters under an Inch even at 200 but things lloked different as the round count grew.

I also was using neck sized brass this time and had a consistent 40-50 fps loss versus full length sized cases.

It looks like the 60 RL26 with 150 Partition is the winner. I may give the 130 TTSX's one more chance but with H4350. Those 100 groups were so promising and I was never about to hit 3000fps with 60G 4831sc.
Assuming you are hunting for meat and planning on a boiler room/double lung shot, the partition should be a quicker kill. If you plan on taking out shoulders, the ttsx may cause less meat loss, but both will work. I love the 150 partition. The .270 is one of the few calibers I haven't switched entirely to Barnes. If you can get anywhere close to 3000fps in an accurate load, you've got a winner.
I put two through a big moose recovered zero. 150 NPT, a stiff load of R22 and a Fed 215M is one of the most accurate rounds I've ever lit off.

Shooting both at 3k.

Any real world, practical (terminal) difference, between the 270 Win/150 NP and the 30-06/150 NP...??

HaYen, if you shoot your 270 better, that's the one I'd take. That 150gr. partition will work just as well as that 165gr NAB from your 30-06. Try some RL 26 and you'll be impressed with around 3,000 fps (even with a 22" tube from my experience). Good luck with your elk hunt..

Yeah, I totally agree. Pick 1 bullet and go with it...
Put one through two shoulders of a mountain goat at 17 yards yesterday and recovered it just under the hide on the off side perfectly mushroom. Goat spun twice and fell over dead...mv out of the 270win is exactly 3000 with RL26.
Cool. that's good info. 17 yds is pretty darn close and the bullet was still scooting along.

How big was the goat? Any idea of what the recovered bullet weighed?

Good for you. Sounds exciting. Pics would be nice (of the goat, that is).
Shot a bull in Colorado last year at feet. Turned into a bit of rodeo but did find the bullet. Its in the post, it weigh 99 grains. No worries on the 0.277, 150 NPT...............

Here's a some pics of the goat, second is a crappy cell phone pic right after the shot. He was probably in the low to mid 200lb range.

Congrats on the nice goat, it's really nice to get them out on the flats. Doesn't happen too often that way.
DJb, I saved the bullet but haven't had a chance to weight it yet. I'm headed out tonight for 5 days to try and round up a bear. I'll weigh the recovered bullet early next week when I get back home.

That's just awesome.

I'm thinking Euro-mount and rug!
