Anyone shoot hornady match 223?

It will be more determinate on your rifle for maximum accuracy potential, but my experience with Hornady 75gr BTHP Match in my DM Courses is that it is very accurate. Hits on 18" plates is fairly easy with it out to 500-600yds.
 
I find it to be very accurate as well. Will shoot under 3/4 all day and most times better if I do my part. I also like the 75 grain hornady TAP, its more expensive and cant tell much of a difference. I stumbled on to the Hornady 75 grain steel match ammo and it shoots quite well. All three loads use the same HPBT bullet I think, not 100% sure on that though. I cant find the steel match 75 grain stuff anywhere right now, it is much cheaper. I run the hornady in 223 wylde 1/8 chambers. I say buy it if its a good deal.
 
I used the 52gr steel match in my AR and it shoots sub MOA for me. Hit a very small ground squirrel at 110+ yds. with one shot. They seem to shoot a little slower than other loads though. Mine were 3250fps vs. most other 50-55 grain loads around 3400 out of my rifle.
 
the 75 gr match didnt shoot well at all out of my dpms ar-15, but the zombie max 55 gr shot moa or better at 100. I really wanted to like the 75, but the gun dictates what I shoot...
 
My Rainier Match 1:8 Wylde SS barrel likes the Hornady 75gr bthp .223 the best out of the factory match ammo I've tried. My local Sportsman's Warehouse has tons of it and 5.56 75gr on the self.
 
Shoot 75grn Steel Match at 3 gun matches. Shoots great from my Seekins SP3G. 1-6x Vortex isn't the best to shoot groups but here is what I did when I was sighting it in. This is at 100 yards.
