Jker,
I'd also like to add this. I'm pretty much exclusively shooting my .223 at 200 yards when I'm playing with it at the range; either bench resting it, or over my day pack. As I did buy the rifle for use (besides fun) as a hunting tool, I'll take a shot or two off of my day pack at 50 and 100 yards, just because. It's totally hunting accurate at those ranges; very.
I used Lapua, Hornady, Remington and Winchester brass when I came up with the load I settled on for a hunting round, which is using 25 grains of VARGET, and the Hornady 60 grn. S.P. (again, my deer round, if I decide to use it on a critter).
Hornady's manual #10 shows this powder charge as 1/10th grain over max, but Hodgdon's reloading site shows 25 grains of VARGET as the starting load on their charts for the 60 grain V-MAX bullet that I mentioned as one of the bullets I load for. This load pretty much fills the case just barely shy of the case neck where it meets the shoulder (as I remember here). I don't believe the bullet compresses the load, but It's probably meeting powder at the bullet's base, or awful close. I've got more than 5 loadings on some of the cases I've used, and none show any signs of an issue.
I've also used a number of different cases of different brands I've found at my local range (lots of LC and PMC for the most part) just to make comparisons on brass, and how the rifle would perform in its use. Seems the brand of brass hasn't made much of a performance difference when full-length resized in my rifle (new, fired or range brass). Extraction on a fired case is as smooth as can be, and I'm quite happy with the performance of my loads, and the rifle. I've got near 700 rounds through this rifle since I got it a year ago last August. More than half of those shots were with the VARGET charge I've mentioned here. Hope this info is also helpful.
