![]() I measured base to ogive measurement using a Stoney Point (now Hornady) bullet comparator tool. There are several bullet comparator tools out there, but the Hornady bullet comparator tool attaches to the jaw of a caliper for quick and easy measuring off of the ogive. I also measured samples of each ammunition, measuring three random cartridges from each box for base to ogive measurement, cartridge overall length, as well as pulling a bullet off one of one cartridge from each ammunition box to inspect the bullet and powder (weighing powder charge and bullet). In cases where fliers were evident, I took a second group size measurement subtracting at most two fliers. But since I shot all of the groups with the same rifle, the results will still be comparative. 2MOA is approximately ~1.36″ at ~65 yards, so this is good amount of inaccuracy when it comes to shooting groups. Note that the group sizes are not going to be indicative of true accuracy because I used an Aimpoint Micro T-1 with 2MOA dot as opposed to using a fine reticle magnified telescope optic. 224″ (to get group sizes from center hole to center hole). Group sizes were measure using calipers edge to edge, and subtracting. Points of aim were 2″ Shoot-N-C pasters on IPSC targets. The Shooting Chrony Alpha Master chronograph was placed 15 feet in front of the rifle muzzle and the targets were at ~65 yards. This is merely some basic comparison testing I wanted to do to satisfy my own curiosity.Īs far as live fire comparison, I wanted to run 10-shot strings of each ammunition version over a chronograph to get muzzle velocity data.Īll ammo was shot using my primary AR defensive rifle build, which utilizes a Bravo Company MFG 16″, 1-7″ twist, mid-length, Cold Hammer Forged, Chrome Lined barrel, chambered in 5.56 NATO, with a BCM Compensator MOD 0. There are other factors that play into the performance of ammunition, including the actual firearm used, shooter skill / error, ammunition lot numbers, etc. I make no final and definitive claims as to one ammunition being better than the other. The comparison testing I conducted should not be construed as a complete comparison or review of the ammunition above. I wanted to include these in the comparison because Federal AE223 and Wolf Gold are very popular, less expensive, and readily available ammo options both locally in stores and online. You will probably notice the above list includes two. Federal “American Eagle” XM193 55gr 5.56 NATO.The ammunition in my comparison testing are: When I chose the ammo to test, it was based on what I thought were the most commonly purchased 55gr M193 clones. So I acquired a few boxes of several different 55gr ammunition to do some comparison testing. 223 reloaders).īut, I did have curiosity regarding the performance of other brands of 55gr 5.56 and. For me, the extra cost per round for Federal / Lake City ammo is justified when it comes to having brass that I will reuse (and is desirable to all. ![]() I know a lot of AR owners tend to buy non-Federal / Lake City ammunition because the alternatives out there are slightly cheaper per round. Thus, I currently buy factory ammunition for general shooting, and handload pure accuracy ammo (e.g. But when the panic purchasing started at the beginning of 2013, driving up the costs of all firearms related products, powder prices and supply has not gone back to the levels pre-2013. The nose of the Sierra BlitzKing is made of a proprietary acetyl resin compound, and the sharp tip improves the ballistic coefficient over the traditional flat-base Spitzer bullet design.Note: Back before 2013, I used to handload all of my ammunition, whether for matches or just plinking. The SierraBlitz King selected for this load is designed for explosive expansion in varmints and small game with the accuracy characteristics of the MatckKing bullets. This inspection equipment utilizes lasers and high speed photography equipment to ensure only ammunition that meets our rigorous specifications makes it into the box.
