New to the .223 Remington

Twist is 1:09

Each gun sings it own song,,, Use what works the best for you.

I bench rest only. 99% of it @ 100 yds. None of my loads are 'max' or 'hot' per the bullet (or powder) mfg's websites, and none have been chrono'd, so YMMV

In 55, I like V-Max using low/mid 23's of Benchrest. The slightly less-expensive Z-Max 55's seem to work decent. (50 gr Z-Max's are a 'no' in my Savage as it peels the hide off 'em and they tumble, even when driven slow.)

Been using Rem 7 1/2 primers for all 223. Same brass as you.

if looking to go > 50 yds as accurately as possible, consider a heavier projectile. 68 - 69 are perfectly fine with your twist, and perhaps ~some~ flavors above that even. (mid 24's of Varget certainly seem to tickle my Varmint barrel just right with 68's @ 100)

The main thing is,,,,, experiment,,,,,,,,, and HAVE FUN!!!

I have a hundred rounds loaded with the same load, and anxious to see what happens at 100yds., then out to two hundred.
Our new 400 yd. range is not quite finished yet.

We have up to 600 where I'm at, but I'm still 'honing my hundred' to perfection, and even then I'll have to be completely and utterly bored before I consider wandering over to the 200,,, (Too far to walk to post a target!!! LOL!!!)

Welcome to THR,
lots of great people here!


Yep you need to remove the crimps, lots of ways to do it only has to be done once.
You will need to have a way to trim the brass, may not need it now but you will sooner or later.
When resizing don't push the shoulder back more than is necessary, a case guage is handy here.
Check for incipient case head separation.
Walkalong has an excellent thread here

I shoot my .223/5.56 in semi autos so I tend to shoot a bunch.
I like powders that meter well thru my measure.
Favorites in order are TAC, BLC(2). H335 and 8208XBR are a tie.

Neat powder pictures here

You can't tell for sure how a powder will meter by it's size and shape but it can sort of give you an idea.

Bullet weights will depend on barrel twist, the heavier bullets will require a faster twist.

Rifles tend to have a mind of their own so there is no way to tell for example if your rifle will like 55s better than 62s or which flavor of either it may prefer.
55-62gr is a good place to start unless you have a slow twist barrel.
