IndianaBoyPRS Gas Gun AR-15 build.
I was exploring every option from 6.5 Grendel, 6mm Grendel and 22 Grendel, to 224 Valkyrie.
Everything but 223 or 308 would put me in open division, and I didn't want to go large frame, so I wound up settling back on plain Jane 223.
Wound up going with a JP carrier and adjustable gas block for the recoil characteristic of my 3-gun rifle, where I can watch my bullets hit steel.
Larue Stealth 20" barrel.
Cross Machine and Tool muzzle brake.
Warne 20 MOA X-Skel mount because my other Warne mount is ROCK solid and the price is great.
Viper PST Gen II 3-15x scope with MRAD turrets and the EBR-2C MRAD reticle.
I shot a .636 center to center 5 round group yesterday with factory Federal varmint ammo from a sandbag while leaning on a wire spool.
Looking forward to loading up some 73gr ELDs to see what it likes.

fritzvery nice
Looks like I lost a bet. I was going for your chambering in .50 Beowulf -- due to its flat trajectory, low recoil, and large holes it makes in paper targets. But no, you stuck with a poodle-shooter caliber.
Assuming you hand load, have you considered the 75 ELD? Very little increase in bullet weight over the 73, but a dramatic increase in BC.

I have considered it but I didn't think it would feed from a magazine.
I seem to recall reading something about guys who were cutting the front of magazines to facilitate feeding the 75s from a mag. Anything to that?

I'm quite certain that I have a bunch to learn and expect to be humbled at my first match.
I'm excited about giving it a go though.
