Peterson Brass in 28 Nosler

[41rem]

Just received 100 pc of this. Now do I start from scratch or take a proven load & begin there?

I'd imagine the .5 MOA load I'm currently using that's 1.5 grain below the Nosler reloading books maximum load using Nosler brass would be safe in this, but unsure. If I drop 2.5 grains I'll be at the book starting load.

I can't speak to a 28 Nosler, but with my .308, Peterson and Noser brass have been pretty close to the same case volumes (the one's I've have, anyway). I would think it'd be pretty much the same for a 28 Nosler, but the only way to tell for sure is measuring and getting a read on the case volumes. I'm inclined to think you'd be just fine going with your proven load, though most likely you'll still have to make some minor adjustment.

FWIW Peterson has a lot by lot listing of all the specs for your brass including internal capacity so you will only have to measure your original brass. Saw this the other day...

Look here & input your caliber & lot#...

Thanks for that link.

Here's a comparison of two different lots of Peterson brass that I have from that testing data:

Another useful feature {at least those that have an AMP annealer} is the Aztec Code # to use and thus saving you from burning a case to get the annealing number.
At the cost of brass these days that is indeed helpful.

One of the reasons I went Peterson was consistent weight. There all at 284-285 grains.

The Nosler I was using were all over the map from 258-284 grains on a sample size of 60 pc.

I picked 20 pc that were between 258-261 grains and have been shooting those 20 only, on reload #4 so far. Started at 79 grains of Reloader 26 with the 150 ballistic tip got 3175, then bumped up to 80.5 grains and 3260 fps equaled 1/2 MOA out to 200 yards. I can work with this as my Pronghorn load

Waiting on some more ballistic tips and I'll start over with the new brass at the Nosler book starting load. Get this load locked in, then move to the 175 grain ABLR with H1000 for my Elk load
