Going at 0.1 will spend lots of bullets for little useful info.
Your 24" barrel probably has a node somewhere close to 3000 but it might be 2960, maybe 3045, bet you a dunkin donut it's not exactly 3000.  Possible but you have to let the barrel tell you where its node is, you can't specify/force fit it by yourself.  Such is the nature of reloading: to find the natural loads that a barrel likes, with small groups and small SD, not the load you tell it to do.

Well said!  I'll add that if Hornady is listing 3050 as a max velocity with a particular bullet & powder charge; Pay respect to the max velocity, despite powder charge may be short of listed max. If you are working with that exact bullet, when you reach max velocity listed, It is most likely prudent to accept enough is enough.

If you have additional loads at higher charge weight, Pulling the bullet may be your best option for the loads with the ,higher weight charges.

Number of good bullet pulling options to choose from. Give Hornady cam over  collet system a look. Choose your vendor, though here is an example.

You will require a caliber specific collet as well if you choose this route.

Inertia pullers are a less expensive option & more universal with no need for the collets. Still I prefer the collet system.
I bought a puller and .3 is doable . I don't need 3000 but would like to be above 2900 for hunting although without gel or water jugs or some other way of seeing bullet expansion I'm guessing what will work . So I thought to ensure best performance I would go with Hornady ballistic charts and energy projections. I am keeping the brass separated and will watch to see how they do . I decapped last night and paid Attention to primer hole there doesn't seem to be any pressure signs except for the last 2 cartridges  which were flatter but after resizing and seating new primers I could not see a deference in the brass
CZ you said to prime then deprime, honestly I didn't know you could deprime a live primier .
I shot the Factory loads first and then low to high, I think my trouble with the magneto speed may have started acting up after the 28.4gr load of reloads they and the factory loads all showed close spreads
So 
check the magento speed after each 3 shot group
ladder in .3gr spread
don't exceed 2950fps for now
and I am going to load some Hornady brass to compare with the starline will start the Hornady brass at 28.4 and catch up
Plus I am going to the indoor range this time I'll be able to look at each loading and swap targets as I shoot to compare group size.
I'm not going to redo 28.4 but will start at 28.7 with the starline brass and go up at .3gr. I'm expecting to see 2900fps with one of the first two steps, if I do and grouping is good I'll stop there and evaluate what I have 
The indoor range is by the hour and by the time I setup and shoot 3 steps in Hornady and 3 steps in starline I should be out of time, hopefully there won't be a waiting line and I can add another hr. if needed


I have Bass fished since I was 10 or so. I am comfortable in what I know there and am in the top 100 in the world for biggest bass. I don't expect to do anything like that here but but I do expect to be able to load and shoot a dependable hunting round and some loads for target shooting . I tend to enjoy a little experimenting but once I find what I want I stick to it.

Thanks for helping .
