It never has been! That's largely because N160 is shown as slower burning in both burn-rate charts and QuickLOAD than it turns out in real life applications.

55.7 grains of n160 was 2850 in mine.
No, it's not. There is a significant gap between the two. I've used N165 in 284/180, a slightly lower capacity case, for many years. A mildly compressed load gives 2,830 from a 30-inch barrel, but good results and exceptional barrel life. It won't achieve higher velocity nodes in either cartridge.
I didn’t throw random loads at it. I done some research and came up with about where I figured the velocity would be. I started 4 grains lower than that shooting singles every 1/2 grain checking for pressures and checking the chronograph. It ended up being exactly where I’d figured it would. Wasn’t nothing random about it. I’m not interested in making shrapnel.

I’m not saying for you specifically I’m saying for anybody in the future reading this thread… people need to be careful because if I was to have gone off of your data alone, 55.7 of n160 would definitely be blowing primers OR WORSE in my guns.
Agreed. It is quite a bit slower than N-160.

Just talked with Jimmy. Been to his shop/range. Good guy.
Yes sir. Im shooting 103 grain bullets in my BRA because of you two. He told me yall spoke today. He thinks very highly of you too.
Not to hijack, but @Laurie what do you mean by “it will not achieve higher velocity nodes in either cartridge”? Are you speaking specifically of the PRCW and 284? I run it in a 284 a little slower than you, but planning on using it as my starting powder in a SAUM capacity wildcat. Am I going in the wrong direction?
Simply that the 284 (and I'd assume the PRC which has only marginally greater case capacity than 284) don't have enough room to increase N165 charges by enough without serious charge compression.
The short magnums have larger cases and hold a bit more, especially the WSM. The base 300 SAUM case holds around 74gn water fireformed, so a bit less in any necked down version. This compares to 66-67gn for the 284 case. Of course, if you plan serious case-reforming reducing the capacity significantly, that could/would change things.
Thanks. Just making sure I didn’t buy all this N165 the nothing….
60+ grains of N-165 can be had in Lapua brass (not compressed) with a drop tube, so give it a try! That assumes your chamber is throated to allow a 180 to be seated at or short of the neck/shoulder junction. Pretty safe assumption, given the reamer prints I've seen.
I'd say most are running 1:8.5". A 1:9" will do fine with a 180 Berger. The 190 and heavier may be better off with a 1:8", but I don't run into too many that shoot the 190+ bullets.
Edited to add - 1.25" straight, 32" length seems to be the norm.

In my 7PRCW l was getting over 2900 with 59 grains of N165
