Reloading for Service Rifle - 223 (New Guy question)

[Shamr0ck]

I believe that shooting service rifle you do not need to overthink the accuracy thing. It is not like taking your 223Rem bolt gun with its 1" bull barrel to a benchrest match.
I would agree with the above in that once fired LCC (or others) will be good. Just stick will all the same headstamp including year.
I would also stick with CCI 400 or 450 depending on your choice of powder. I use AII 450's no matter the bullet or powder used.
I shot several different disciplines but never service rifle. But I have a buddy that was a champ at it. I will give him a call and see what he has to add. --- SAWMAN

Thx!

One of the thing s I want to get out of this process is an understanding of the why certain decisions are made...

How does one go about making the primer decision based on powder?

Given a supply of reloader 15 I’d like to start with that though I know it doesn’t measure well in a Dillon (too frugal to not use - but admittedly it may be less expensive to use a ball/flake powder which will)

Related ? - I’m familiar with powder lists by bullet from my reloading manuals and I’ve seen a powder burn rate chart. What I’ve looked for and not found is a reference which lists powder type (ball, flake, extruded) by powder as a way to help decide which to use.

Reloader 15 is said to be pretty temperature stable - wonder if there is a resource which speaks to that too?

Thanks again to all for weighing in

ETA - just saw the 450 is spec’d as a magnum primer for ball powder and the 400 is a standard SR primer
