27 Nosler loads?

Hmmmm... they really loved 7977. In fact it's shaded sd THE best powder threu tested and I didn't see it right away. I think US869 is Unicorn Dust in today's market. I'll look but I'm working on getting that 8133.
I've used both 7977 and 8133 in my 2 7mm LRMs. The 7977 always needs grain-ish more to match velocities with H1000, but shoots very good. I tried the 8133 in my 6.5 PRC and couldn't get the velocity up to H1000 before running out comfortable room in the case. Then I tried it in my LRMs and it shows promise, it really fills the case well so it has good uniform ignitions no matter the rifle angle. I'm still working the load up with it. It should do well with the big case capacity of the Nosler. I'd try both powders if I were you.

Something I've noticed on these new IMR powders in my barrels is they clean out really fast and don't seem to be holding as much copper. But maybe that's just my case.

Most books will tell you that if you use a 150 grain monolithic you should be running a 1:8" or faster twist barrel. I built a heavy twist barreled 270 wildcat. the best thing I ever did was go with a 1:8" barrel. it made the 150 grain Barnes into match bullets. I am waiting for the 27Nosler to become a bit more prolific then I am going to have a gun built. I have an action waiting for the build. When in doubt go with a fast twist.

What twist rate is in your 270 Win? That s a long bullet it appears
Regular old 1:10. Woodleigh makers say it is just enough to put the spin on their 180s. As a departure from more reasonable bullet weights it is a fun experiment. I am not recommending it due to my experience. The first shot tend to string, the second and third shots tend to touch, at max load. I am looking forward to Nosler's 165 bullets. Once I am out of 180 woodleigh I won't buy more for this 270.

I would not say woodleigh is lying but I had a 1:9.5" twist on my Savage 110 270 Win. it would hardly keep the 140 Barnes and 150 grain Berger projos stable. if I went below max load, I could not hit anything with that 270 win with 140 grain Barnes. that is why I tell people that if you shoot heavy monos and anything over a 145 grain lead slug get a 1:8" or 1:7" twist barrel. I know from personal experience that 1:10" does not stabilize the heavier stuff.. let alone the 160 through 180 grain VLD hunting slugs.

I have had real good results from 150 grain nosler partitions in my 20 year old, Rem 700, 270. I would say the 180s should be used inside of 100 yards, and, maybe in heavy brush. 180s are not ideal. And, I just gotta try those 165s when they come out. And, if I ever rebarrel a 270 I would go 1:8.5 or something like that. I think the 27 nosler rifles made by Nosler will be 1:8.5..?

Using starting loads for the 28 Nosler with similar bullet weights might be another approach if cases same.

Old thread bump but for future record, the 27 and 28 nosler case shoulders are at different lengths, the 28 being a little longer so it has a larger capacity.

This fall my smith built me a sweet Nosler 27 on a defiance action. For what ever it is worth the 27 brass is more similar to the Nosler 30 than the 26 or 28. Nosler 27 brass and even the 27 ammo is still around. About 2-3 months ago it was a steal, of course higher now.

1:10, like shooting pencils. Woodleigh says 1:10 is just enough, reloading gurus say 2550 fps is minimum needed in 1:10. I can just achieve that 2550. But, first shot tends to string a bit...then #2 & 3 tend to clover leaf. Consistently. 7828.
