All depends on what powders you have and what powders you can find.
My CZ Model 3 luvs the 165gr Partition and MRP.
My Browning BAR luvs 165gr and 180gr Partitions and Ramshot Hunter.
If I could not find either of these I would go with R-17.
If you took the time to look at the charts posted above you would have seen that there is no direct correlation between case weight and case capacity. A heavier case does not automatically mean less capacity.
If you look at the data closely you will see that the pressure did not start to rise until the bullet was seated over .250 off the lands, that enormous, I have no rifles that could be seated that deep.
Also notice that even with the bullet seated .450 (almost a half and inch) deeper into the...
Long throat or short throat, seating deeper in a bottle necked rifle round will reduce pressure.
From John B of Handloader/Rifle Magazine.
Seating deeper decreases peak pressure, for two reasons. The longer "jump" of the bullet to the rifling results in a lower peak pressure, since the bullet...
This is another reloading Myth that will not die.
Military 5.56 brass does not have less case capacity then it's civilian brother the 223. In fact Most Military Brass (LC) has more case capacity than 223 brass.
This is from Sierra.
The conventional wisdom to reduce loads with military brass...

One place you will find it is in the Nosler Manuals.
Read the last paragraph. There is more to this then just finding Max OAL.
Sorry, if posting this picture is a violation of the rules, Delete if necessary.
When I fire-form for my AI's I load 16gr Red Dot, Cream of Wheat and cap it off with a small cleaning patch.
No bullet, no barrel wear, no wasted bullets.
Course, I am of the camp that my brass should be fire-formed before any load development, YMMV.
Looking through all the different data available in Quickload I found something I do not understand and could use some clarification.
When QL calculates a load the list several bits of information. One of these bits of info is "Muzzle Pressure".
It appears that the slower the powder the...
What is your barrel length and your case capacity?
Here it is again in an easier to read format with 24 inch barrel and default case capacity of 28.8gr.

Nice shooting, but...
I don't think you have a large enough sample to come to any real conclusion as to OAL vs Accuracy. A larger sample may prove you conclusions accurate, but then again maybe not.
Once I find a magic load I shoot several 5 shot groups to verify.
When running Quickload for the 223 it's best to take an accurate measurement of case capacity in grain of H20.
Quickload's default case capacity for the 223 is 28.8gr of H20. This is on the low side for most of today's 223 brass, in fact I have yet to find any cases with less than 29gr of...

Is this New bullet going to be offered as a component in the near future?
