I am able to get 3,613 fps from my 28 Nosler with Hammer 143gn and N570.
I have made hundreds of 28N from 338RUM if your going to try with just one die and used brass your going to have a high lost rate. it takes 3 dies to do right
338RUM die with bottom cut off or 33N die adjusted properly
300 RUM or30N same as above
28N die
start by trimming to 28N trim length lube and start with 338 size and rotate 3 times next 300 same as above then on to 28N die. to help with spring back slide .010 feeler gage between shell holder and brass as needed so you wont have to keep adjusting your 28N die
Can't you just get a 28N FL bushing die and the appropriate bushings for necking down in steps?I have made hundreds of 28N from 338RUM if your going to try with just one die and used brass your going to have a high lost rate. it takes 3 dies to do right

As the picture shows you are not just necking down, you have to essentially form a new shoulder and neck.
I agree to that, however a prior post states that a 33N die, then 30n die, then 28n die adjusted properly would work. Isn't a 28 nosler die with larger bushings essentially taking place of the other two dies? I'd start with 338rum brass, as it has the shortest shoulder of all the ultra mag cases.Exactly!
I don't understand that process either. A 30 Nosler die is .051 shorter in the shoulder than the 28 Nosler die. Why would you use that die? To size the body? That doesn't make sense to me as they are both based off the 404 Jeffery. I don't really care what you do. Just my experience you don't need anything but the 28 Nosler die and I didn't mess 1 piece up and did 20 in about 30 minutes.
