That will be sweet! Any bc claims?
Awesome news! I hope the BC is in the .550 range. I really wished it was 155gr or so. That would be awesome. But beggars can't be choosers!
I would really like to see the 147gr for 1:10 barrels and then like a 155-160gr for the 1:9 or 1:8 custom barrels. From doing some comparisons between SSTs and ELD-X bullets in other calibers, I believe the 147gr .270cal ELD-X will have a G1 BC of .575-580!

Lets talk about something that is available. I got to the range today with my 28 Nosler and a short ladder test. I noticed in Noslers new data book that they listed RL-50 on top of the velocity heap for the 168 grain pills but they didn't list it at all for the 175 grain pills (like the 175 gr ELD-Xs). I figured RL-50 would be the cat's meow with the 175's so I did some extrapolation and loaded up a few to see what was what. I ended up with the target below. As you can see the first two shots were not so tight but not bad after that. I have no clue as to why #2 landed in another county and didn't want to be with its friends. A bit more data: I also had 2 shots loaded with RL-33 (for which Nosler does provide data). I shot those two after the target below and they landed in the same spots as 1 & 2 (on another target). So the rifle wants to either go left (6 out of 8) or right but nothing anywhere else. I'm going back to the range with 5 each loaded with RL-50 at 88.0, 88.5, 89.0 grains. I'm hoping that there is a pretty wide node around 3,200 fps and the max load all decides to go left. Anybody care to hazard a guess as to what will really happen?

Could be a number of things.
Without a brass prep list I can only surmise.
Neck tension and bullet concentricity come up.
Brass runout also.
Shooter maybe?? No offense but it happens.
I would check all aspects of your brass prep and loading process
I also would try RL 26. I have had great success with it on cases from 243 to ultra mag size. 33 and 50 will collect dust from now on at least on my shelves
Are you limited to Alliant Powders? Retumbo seems to be a good powder in the .28 Nosler and should get you 3200fps with the 175s.

Brass was new virgin 28 Nosler headstamped brass. Runout 0.002" or less. Neck tension set for 0.002" and bullets went into the cases as they should (easy). Shooting from a Lead Sled which is pretty dead still and no shots were pulled.
Too be clear I'm not asking why it threw a couple of shots but I'm really asking from looking at the target (where two shot groups got tighter as the powder went up), if you think there is a node at 3,200 fps and will it put 5 into a small group next time out? I'm thinking that it will but... we will see. If there is no node it should continue to rattle between left and right, no?

I've got Retumbo, RL-26 and pretty much everything else. The reason I loaded RL-50 is I saw it gave the fastest velocities in a bullet 7 grains ligther than the 175s per Nosler data. Why not go for top speed? At that velocity (3,200 fps) this thing will kill stuff past 1,200 yards.

I've got a feeling you are right about the lead sled as to it messing with your vibrations/nodes etc. I will shoot the rifle normal (front rest and rear bag) if it groups with the Lead Sled next time out. That in itself will be interesting to see if you are right. Common sense says that shooting a virtual 60 pound rifle has got to be different than a 10 pound rifle in more ways than recoil.
