Today we continue the ammunition consistency testing by adding another .223 Remington round to the leaderboard. It’s kind of like adding a car to the board of lap times on Top Gear, except instead of The Stig you’ve got this slob right here, and instead of witty commentary with stunning video you get some statistics and science drivel with a couple crappy still photos. But hey, it’s not like you really wanted to do those TPS reports anyway so let’s get testing.
As all good studies and reports do I’m clearly stating the testing procedure and output metrics right up front. Well, more like linking to them in this here post but they’re still being stated. The only difference is that we’re now using 20 round samples of ammunition.
Speaking of samples of ammunition today’s offering is Remington’s Premier Match .223 Remington 77gr product, something that seems perfectly suited for that portion of the National Match crowd who are too new to know how to load their own ammunition, too lazy to make enough rounds, or too rich to care about the price. I’m pretty sure I fall into two of those categories (with aspirations of falling into the third), so in other words it’s a round that seems purpose built for me. But how well does it stack up against the competition?
BOX PLOTS! I love box plots. So much information in such a small package. The new ammo under examination is on the right, accompanied by a selection of other brands for comparison and the current reigning champ (Wilson Combat). Remington is certainly more normally distributed about the median than the other brands, but does that translate into smaller IQR? BAR GRAPH TIME!
Huh, looks like Remington’s Premier Match ammunition is just slightly better than the average .223 Remington offering. Considering the thing costs a buck and a half a round I expected a little better performance, but the IQR is still nothing to sneeze at. For the money it seems like Wilson Combat’s 77gr offering (at $0.02 more per round) is the better deal, but Wolf will do if you’re cheap and in a pinch.
Join us next time when we test yet more brands of ammunition and give you flashbacks to high school statistics classes.

Well I enjoyed that. Then again, I like browsing the cleaning products section at Home Depot.
+1 for a Top Gear reference. The last conservatives in England deserve lots of praise 😉
What does iqr stand for?
After reading this, I wonder if six sigma misses me…
