Home Forums Reloading Big Game Rifles 270 winchester

Yeah yeah I know it's gay if you want a real man rifle neck it up to 284 and you have a cartridge that can do it all.. Anyhow was at the range week or so ago. Testing loads for an upcoming sheep hunt. 99% sure going to use 150gr partitions. I did load some 130gr Sierra game king btsp, the groups it turned in has me rethinking things lol. This data was pulled straight from accurate powders manual.
55.4gr Hunter
WLR primer
F-C cases
130gr Sierra btsp
OAL 3.275 BTO 2.780
I read somewhere on the internet Jack O'Connor liked using this bullet for sheep hunting.

Now my 150gr part load is shooting pretty damn good. All of these loads shot less than 1/2 inch groups at 100yds

60.3gr RL 26
FED 210
F-C cases
150 part
OAL 3.320 BTO 2.788

51.5gr RL 17
FED 210
F-C cases
150 part
OAL 3.320 BTO 2.788

Ol stand by of 57.0gr H4831 was nothing to sneeze at either just need to seat bullet out a tad further.

I just ordered a bunch more 150 part so looks like that's the bullet I will be using on my TMA sheep hunt this August.

It looks like you answered your own question - you will be using the Nosler Partitions. That's a good choice, better than the 130 grain Sierra. I would want a tough bullet for that hunt. I plan on using Barnes TSX bullets in my 270 for my upcoming elk hunt in Colorado in November because they shoot very well in my rifle. Stick with what works and good luck.

150NPs out of a 270 are extremely deadly. Will be the nuts on sheep I am sure. Work well on
mulies and elk.

79S. I too have a soft spot for 270s and 150 grain bullets. I have landed on this recipe.

Game Kings have turned in some NICE groups.

It has been a solid , very accurate load in the half dozen or so 270s I've shot it in.

I'm still on the fence as to what bullet to load for my Muley hunt this fall. Waited 11 years to draw,and still tinkering with bullets. Is that a Looney or what? Big open country. Shots could be long. Hey, it will give me something to do this summer. Right? I'd like to find someone with the Scirocco II,that would send me 6 to try. Hate to buy a box of 100, and not like them.

Good luck on your sheep hunt. I'm envious!

That's no way to end up with a bunch of partial boxes of bullets!

I loaded up a bunch of the GKs over just 55gr for practice. Nicely accurate, and my "business" load of 160gr NPs over W780 lands just under it. Long shot opportunities are pretty rare around here so my .270 is more like a 7 by 57 usually.

As to the 150NP in 270s and mulies....
I had a mulie buck moving down a tree line and headed for an opening of about 25 feet at about 150 yards out.
I shot a little behind where I wanted. The bullet hit behind the diaphragm only hitting skin on two sides and
the stomach. The buck dropped like a rock, stood up and fell back over quite dead.
No bones or vital organs hit and one quite dead mulie buck.
I personally love Nosler Partitions.
The 150s in the 270 make good elk medicine and should be about perfect for sheep. The 130s are good on deer
also and would surely make good sheep medicine also.
Just my 2 cents.

Long ago I decided to split the difference, never had a problem with 140 gr BTSP Interlocks. High shoulder shots or soft tissue lung shots put mule deer and elk in the freezer. I've used various 130s on deer and antelope and the difference in trajectory is only slight, if perceivable at all, with the edge going to the 140s past 600 yards (when comparing apples to apples).

If the 150s shoot in your rifle and that's what you wanna use, learn your dope and bang away. Happy Hunting!

I've seen more elk killed with the 270/130 combo than any other cartridge/bullet combination. The 130 kills beyond its "numbers" and I really have never seen the need for more bullet up to and including elk.

I like the 140 Accubonds

I have killed 3 elk with a 270 Winchester. 2 with 150gr Nosler Partitions and
one with 140gr Accubonds. I think the Accubonds provided a little Quicker kill
than the Partitions. This year I,m trying out the Federal Trophy Bonded Tipped
loaded 50 last night with 4 different powders. Norma MRP, Superformance,
RL23, and RL26. We will see which is the most accurate. I,m using the 140gr bullets.

Sounds like you are good to go.

FWIW, I had a pre-64 model 70 in 270 Win. It shot very well with a 150 grain flat base Hornady spitzer with an “under max” load of AA3100. That load/rifle would produce quarter-sized groups at 200 yards, and dime-sized groups at 100 yards.

Otter6: I've used a load very similar to this with very good accuracy and it is deadly on whitetails and several 300+ lb. Russian boar hybrids. My load is 57 of 7828, Win LR primer, Win. or R-P cases, and Win. power point bullets. We inherited the rifle (old Ruger 77) and more of the bullets than we could ever shoot. I usually hunt with a .30-06 and my daughter uses the .270 but for a while I used it exclusively at night for hog eradication because it had the only lighted reticle scope we owned.

79S, I think your 150 Nosler choice is a good one. Nosler Partitions are never a wrong choice. BTW I have found that in several 270's that I load for 150 Sierra's shot to the same POI as the N.P. so I sometimes use the less expensive bullet for practice.

Chances of seeing a Brn bear are pretty good as well. So that's why I'm leaning towards the Partition, but know guys that killed Kodiak bears with regular ol hornady c&c bullets as well. The partition has a decent b.c I don't plan shooting past 450yds for sheep anyhow..

Just got in from trying out the 145 grain ELD-X. Accuracy could have been better. Right at MOA @ 100 yards. That was with my 7828 pet load. At any rate, it stood it pretty good. Plowed one into some heavy water jugs. One common milk jug,three Tidy Cat litter jugs and one more milk jug. Jugs were set at 100 yards. Surprisingly,it didn't go to complete chit. Caught it in the fourth jug. Retained weight was 87 grains. Fairly long shank too. A lot of the core was shed not being bonded,but no slippage. They were seated mag length. I may try some RL26 and gold medal mag match primers next.

CYM that's all I use up here in Sask on our big deer. The 140gr Hornady BTSP is a great bullet. Wouldn't think twice to use it on elk or moose either. For that I have a 338-06AI. But that 140gr BTSP holds together well , carries energy way out and is, I think, the best weight bullet for the 270. I've shot bullets from 110gr to 160gr but can't justify anything but that 140gr weight for all ungulates.

Superformance beat out the other powders for accuracy with the 270 win. RL23
was second best powder. LabRadar quite working, no speed.

I wish my 270 would shoot partitions well, it just throws them friggin everywhere. The best controlled expansion bullet I’ve found for my rifle is the Federal Trophy Bonded, and they’re cheap too!

My 270 Winchesters shoot 150gr Partitions very well, I use about 59gr of Norma MRP. Close to
3000 feet per second. I,m only changing because I wanted a little more expansion. Just
an experiment, open to changing back later. Talk about accuracy, I have about 500 150gr
Deep curls that are the most accurate bullets I ever tried in a 270 Winchester. Problem is
I get pressure signs at about 2900fps no matter what I do. Any ideas?

From what I found most are keeping them below 2900 FPS.
