WHO NEEDS complement GRADE as soon as THE key OBJECTIVE IS TO put SOME ring DOWN selection AND have SOME FUN?
When i left the battle in 2007 and came home, i was searching for something to complimentary my mind. Something to help me focus on tomorrow and also not what taken place yesterday. I discovered it in reloading. One could imagine just how excited i was when offered the possibility to compose an article about handloading ammunition.
The premise that this write-up is to find the many accurate handload because that .223 Remington/5.56mm NATO, v commonly obtainable powders and projectiles because that the least amount of money.
I have used so numerous different types of projectiles end the past decade make the efforts to feed my tradition AR, I have lost count. Sure, you can pay a many money for complement grade projectiles, however what around those of us who simply want to shoot something that’s accurate and inexpensive? with trial and also error and a bit of selection research, I believe I have uncovered a few combinations the just could fi t the bill.
Since one goal is accuracy, I determined to begin with brand-new Hornady cases, all from the very same lot. Since I had actually so many cases to process, I began with my Dillon 1050 supervisor to process the brass fi rst. Loading this much brass, ns fi nd it faster to size and also prime in one go, then head come the single-stage push to fi nish turn off the rest of the process. My stand-by is a classic Hornady single-stage press.
Since we desire to see how accurate these hand-selected projectiles yes, really are, I want to fill all 3 projectiles v the exact same powder and also charge weight so we might really see which bullets showed the most accurate. I supplied three powders: Varget, IMR 4166 and Alliant’s AR-Comp. The projectiles that I chose to use space all 55-grain full-metal jacket v a cannelure.
To save the to compare equal, every projectile gained the same powder charge with the matching powder type.
Even though the three various bullets being provided are of the same type, there are some slim differences between them. The cannelure space at slightly various locations, requiring various seating depths. Every projectile seating depth were set to the center of the cannelure. Following that, seating depth top top the cannelure will certainly assure that loaded rounds will certainly not exceed the maximum over-all size of 2.260-inch. This will certainly assure the ideal OAL for each specific bullet and brand.
To make the loading procedure a little easier, i ordered increase a set of Lyman loading blocks from Midway. This loading blocks room machined indigenous a solitary piece that aluminum and are precise fi t for the .223 Rem cartridge. This ensures the there isn’t any type of “wobble” with the instances when trying to drop the powder charge, and also it no hurt the it will certainly make any kind of loading bench look at great. While making use of these loading blocks, I also like to use the caliber particular machined aluminum powder funnel from Xtremehardcoregear.com. Since they room made native machined aluminum, lock are normally static-free. They room precision machined to fi t your particular cartridge, for this reason this way no an ext powder spillage between the funnel and case-mouth. It might not seem choose much, but having a loading block and also powder funnel that are specific to the job really does assist the effectiveness of the totality operation.
I determined to begin with Varget, and also I invited 50 rounds each because that the Hornady, Berry’s and also Bob’s bulk Bullets. Each case received a fee weight the 25.5 seed of powder. This left me with plenty of ring to fi re three 5-shot teams at 100 yards, and shoot 10 rounds per batch v a chronograph to obtain an idea the the shot-to-shot consistency. These rounds had the greatest standard deviation (SD), but were quiet pretty consistent. The finest 5-shot team with Varget was v the Berry’s cartridge measuring in in ~ 0.68-inch and also the largest team measuring 2.16-inch.
The second powder provided was IMR 4166. As soon as again, 50 rounds were loaded for each bullet with a powder fee of 24.5 grains. This powder provided a much tighter too much spread (ES) and a respectable SD. The largest team fi red measure in at 2.74-inch shooting the Berry’s bullet, and also the smallest team shot measured 0.55-inch. An interesting allude here is that this group was the smallest five-round team fi red because that this article.

The last and also final powder supplied was Alliant’s AR-COMP. This powder was loaded through a charge weight the 23.5 grains for all three varieties of bullets loading 50 ring each. This powder had actually the the smallest SD and also provided us through the the smallest average team size of 0.98-inch for a string of three 5-shot groups. The projectile fi red in this group was Bob’s bulk Bullets from .223bulkbullets.com. This projectile performed an extremely well, and also had the second smallest team size for this article, measure in in ~ 0.65-inch. Choose I stated earlier, this bullet-and-powder combination had the the smallest average team size of just 0.98-inch. Given that the as whole cost that this bullet, consisting of shipping, is the shortest of those tested in this article, and are repeatedly available. These are, in mine opinion, the finest bullets around for the job at hand.
