Would 3300 be achievable in a 26 in barrel with 165 matrix and 170 bergers
not in a 26 in barrel and brass wont last more 2-3 fireings

Sorry Can1010, I disagree. If you have a 27 Nosler, I would love to share data and refine the advice we can give.
Yes it can be done.
It's not nice on your brass.
It would be better to go with a 28" barrel and back down just a bit.
ADI AR 2218, VV N570 and RL-33 can all do it.
In my Weatherby Mark V actions, non-issue. However my 27 Nosler test mule is a R700. Gets sticky bolt at about 57K psi.
It would take 57k to 62k psi with the above mentioned powders.
I am using quick load data you gave me early last year. only powder used RL-33. started at 84 high was 89 @3295 but killed brass 3 reloads. now using 87 @3250 with coated bullets. gun is savage 116 with 27 in benchmark 1-9 done on shoulder no nut
what measurements you looking for. berger quick reference has them. if you need a few pm me will send some
Hi Gene,JF, How have you been? Busy mad scientist'n and tinkering with cartridges Are you still working with 27 nos ? Have you heard any rumours if Nosler is going launch 27 in factory round anytime soon? I've been working successfully with 170 Berger in my 270wby. But if I knew which way Nosler was going togo with the 27 case design I might start a new build in spring. I looked on SAMMI site and didn't see anything for 27 Nos. As in how is Nosler going prevent 26,27&28 from cross chambering. Winchester moved 270 WSM's shoulder back to prevent 7mm from chambering in 270.

JF, which brass would be better to resize. The 26 and move shoulder and neck up or 30 neck down and no shoulder movement. Then there is the 28? What have u done and found produces best results? The dies will be in late Oct. I think I'm going to look into Benchmark barrel. I believe I can get a 1:8 fluted barrel if i recall past research I did. Already found a donor 7mm Sav. 110 donor.
Thank is again.
Gene
I can't find my 30-Nosler drawing, so, I don't have a good answer on which brass to use. From PTG cross reference chart, they are not the same. If the shoulder location is the close on the 30 vs the 27 it would be much easier to use 30 than anything else.
An 8tw for the 195s sounds good to me. I used a standard 10tw but it was just for testing.
I had all my chambers made with the same go/no-go gauges.
