Brass reloading question

[live2huntelk]

I have 3x fired 300 WM Winchester brass that I have loaded and fired in my Remington 700 Sendero SFII. I use a Redding competition full body die when prepping the brass. I recently purchased a used Rbros 300WM. My question is, should I get unfired Winchester brass and shoot/fire form for the Rbros rifle or can I just use the brass I used in my Sendero. The one thing I would check is the shoulder bump when prepping the brass for the Rbros vs the Sendero. Is there other considerations/concerns of using brass fired in a different rifle?

I would think as long as the reamer used for your new build is a no turn Neck u should be fine. I would throw a piece of your brass in it and feel how the bolt closes. Depending on chamber dimension differences u will either be fine and just fire your current brass basically fire forming it to the new rifle or B u won't be able to close the bolt on your current brass and will have to bump shoulder back a little at a time until bolt closes to your desired pressure

I have two 300 win mags. One I use for hunting and one I use for long range shooting. I keep separate brass for the two different loads.

Resize, ensure it will chamber and if so fire away.

I would get separate set of brass. I'm really liking the ADG 300wm brass. Very high quality and I paid $60 per hundred. My lot had .014" neck thickness, all around and had only 2.5 gr difference, from lightest to heaviest on 200 cases.

I would size it and play.

As long as its full length sized and chambers fine I would use it and have fun

There are areas near the case belt that doesnt get sized.

Keep separate brass for the two different rifles.
