That's two grains above Nosler and Hodgdons book load. That might be it.
Might be, I've loaded both 55 and 57. Not a lot of difference at 100yds.

Okay. Maybe clean the barrel before shooting different ammo.
Always clean my firearms religiously until I get them set, then clean as needed...
That is a hot load for the 150gr. Did you get any preasure signs? Ejector marks or flat primers? Sticky bolt?
What I woukd do is load both up again. Shoot the 130gr first, then sight in with the 150gr and see how they group. I'd also lighten up the 150gr load if there are preasure signs.

It are the 57gr, 25 rounds to be exact, no issues. As mentioned to 130gr was a factory Rem load. I will however be loading the 130 and 150 next time.

Different ammo can cause a shift in POI. It's more obvious with AccuBonds and mono's but powder changes can do it too. Hard tellin not knowin. Might be one of those circumstances of pick a bullet and sight in and leave it alone.
You might be correct, like I said before, next time should prove to be a better testing day.

YUP,. THIS ^^^ Stay with,.. ONE accurate, Bullet !
KNOW, your Rifle and Load !
I'd prefer, the 150's, in a Standard .270 Win as, they WILL,.. Hit harder, Buck Wind better and Penetrate,.. DEEPER !
Keep, the Rem Brass but,.. shoot the Factory 130's up at,.. Rocks ( BIG, Rocks ! ).
I shot some, Rem 130's in my .270 WSM, Tikka and they grouped about, 1.25+ inches in Dia. and 4 to 5 inches OFF at, 100 yds in, a Sub, 1/2 MOA Rifle, using 140 gr. Classic Hunter, Berger's ! The Rem Coreloks are, Flat Based, the 140's have, a NICE Boat Tail !

I'm hoping the rifle will end up liking a 150 over a 130, but time will tell.

I've had several .270s, with #2 and #3 barrels. All of the ones with the #2s were finicky, shot one weight super, the rest squirrely. the #3s shot different weights well, but seldom close to the same zero. "A rifle that will put different weights into the same zero is to be cherished and shot little." (Jack O'Conner) while we have better bullets/barrels/powders than ol Jack today, it still is pretty accurate...in my opinion.
Also, I put this together a short while ago from several different resources to get an idea of where I wanted to start from. Maybe someone else can benefit from it? *** USE AT YOUR OWN RISK, I AM NO ONE, NOT EVEN FROM EARTH***
.270 WSM Load Data
- Savage 270 WSM and its running @3225 FPS with the 145 ELD X and 69gr Retumbo 1/2 MOA to 750yds
- 140 Accubond 59.0gr RL-17 CCI250 Primers COAL 2.825 MV: 3,080 out of a 22in barrel 1/2 to 3/4 MOA
- 140 gr. Accubond, 62.5 gr. Imr4350, Fed215, Win brass. 3150FPS. Model70 Winchester Supergrade, McMillan Stock. .25-.5 MOA.
- 140 Accubond over 63 gr of RL-19, .015 off the lands. Fed 215 primer.
- 66 grains of RL 19 out of a 24"bbl I was getting 3200 fps and 1/4" groups
- I have a 270WSM load that is 69.5g of Retumbo with the 140g Accubond, Fed. 215 primer at about 2.870"
- My 270 wsm likes 150 Nosler BT over 70.3 Magnum with a cci-200 and Winny brass. 3118 fps. Deer have been impressed.
My target load is 150 SGK over 62 H 4831. Sub 1/2 moa at 100 yds. - 130 TTSX @ 3250 fps with 62.5 gr IMR 4350, Federal 210 primer.
- Shooting 1/2 MOA at 500 yds with Nosler brass, 140 gr accubond, 68 gr MagPro, and WLRM primers. Shoots equally as well with 58.5 gr IMR 4350.
- 140 Accubond, RL-22, and a fed 215 primer.
- Winchester case 72.0 grains Retumbo CCI 250 primer 130-grain Berger VLD
mv (in my rifles across and Oehler 35P): 3327 fps
This has been my go-to hunting load for several years. Sub-moa in my rifles (Winchester 70 and a NULA M28). This would not be my first choice for elk, as the Berger hunting bullets are a bit soft, but it's excellent for deer and pronghorn. If elk is on the itinerary, try a TSX bullet. - Safe in my rifle but be sure to work up. 66gr H1000 150gr Nosler Partition 66gr H4831sc 130gr Nosler Accubond
Both in Winchester brass and CCI 250 primers. - For the 270 WSM I am trying 130gr SSTs, Winchester cases, WLRM primers (yes I have pulled the WLRs), AR2209 powder and bullet seating 0.6mm (20 thou) off lands. A slower powder such as AR2213SC (= Hodgdon H4831SC)
- I know this is an old post but here is what I have found. Hornady 130 SST use powders
RL19 61.5 grains
IMR4350 60.0 gr
H4831 62.9 gr
AA3100 65.6 gr
WMR 69.1 gr
N165 67.9 gr
these are max loads - ***270 H4831 57.5 Speer grand slam 150gr 3.250 coal ***
