Shooters are some of the strangest people on the planet.  Shooters will spend thousands and thousands of dollars on their handguns and their gear to ensure that they have every possible advantage when they step up to the firing line, but then they race out to buy the cheapest components for ammo they can find.  The ammo issue is real!  With great ammo, you can turn a $400 handgun into one that shoots as well as a gun that costs many thousands.  The opposite is true as well.  Sometimes cheap ammo can turn a handgun that cost many thousands of dollars into one that shoots about as well as a cheap one. <\/p>\n\n\n\n

One thing every shooter should be looking for when selecting a bullet is accuracy. There are many manufacturers on the market but just because the company has a big name and marketing dollars behind it does not necessarily mean it is the best. And as with everything in the shooting industry, the cheapest stuff you can get is often cheap for a reason. That said, I\u2019ve found that it\u2019s possible to get high-end components from a small manufacturer for close to the prices of the cheapest out there. There are companies out there that will design, perform all the tests, and give full commitment to creating a superior bullet. RMR is one of those companies that produce match proven results but without the high dollar advertising campaign.<\/p>\n\n\n\n

\"Bullets<\/a><\/figure>\n\n\n\n


Over my career, I have shot hundreds of thousands of rounds so when I am testing the product I quickly know what I am looking for. Consistency in diameter, weight, and profile of a bullet all contribute to results. And keeping it in an attractive price range for the consumer is very important.<\/p>\n\n\n\n

RMR Bullets<\/h2>\n\n\n\n

Rocky Mountain Reloading (RMR), is a family-owned company in Lewiston, Idaho. They manufacture a complete line of match quality 9mm bullets, but they also offer a variety of other products for the reloading community. The bullets tested in this article are RMR\u2019s 9mm 124 JHP MPR (.3555\u201d). MPR stands for Multi-Purpose Round.  They say they named it MPR for three reasons: First, it was designed to work in 9mm as well as .357 Sig. Second, the hollow point isn\u2019t just for show but actually functions as well as high dollar self-defense hollow points.  Lastly, it\u2019s priced low enough that you can actually afford to practice or compete with it. <\/p>\n\n\n\n

<\/p>\n\n\n\n

\"Bullets<\/figure>\n\n\n\n

Upon opening the bag the first thing I noticed was the clean appearance of the bullet. Some attention and care was given to the final tumbling of this bullet. I appreciate when companies do this as some of the larger manufacturers sometimes will deliver bulk bullets with sizing lube still on them. I\u2019m very compulsive with this and will typically throw the bullets in my tumbler to polish them off. But over-all, for the style shooting I do, it really doesn\u2019t matter. I just appreciate a company that takes pride in the cosmetics of their product.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"Bullets<\/figure>\n\n\n\n

As with any bullet, I always measure the diameter for consistency. For this test, I randomly selected 20 bullets of the thousand round package. The bullet proved to be very consistent with every one of the 20 bullets measuring .3555 exact in diameter. And with this consistency, it typically means that one of the most important control measures has been met. Not all bullet manufacturers maintain this degree of consistency. But at the price point RMR offers, this is pretty phenomenal. We will talk price later.<\/p>\n\n\n\n

The problem with bullets that aren’t consistent in diameter is that the rifling in your barrel does not contact the bullet consistently with the same amount of engagement into the jacket and seal during combustion to provide equal pressure for each round. This can lead to a wobble or tumble of a bullet, and also not maintain minimal standard deviation\u2018s in velocity. <\/p>\n\n\n\n

<\/p>\n\n\n\n

The bullet proved to be very consistent with every one of the 20 bullets measuring .3555 exact in diameter. <\/figcaption><\/figure>\n\n\n\n

The next important variable is bullet weight. Now I am not too concerned if my bullets don\u2019t weigh the exact \u201cas advertised\u201d bullet weight. What I am concerned with is the consistency of each bullet. Don\u2019t misunderstand me, a 124-grain bullet as advertised should not weigh 132 grains. But if the allotment weighs an average of 123.8 grains or 124.3 grains then that is fine. What is most important is that each bullet has minimal weight variance from bullet-to-bullet. <\/p>\n\n\n\n

The reason you want a very minimal spread on bullet-to-bullet weight is because if you keep all variables as close as possible when reloading you limit the margin of error that occurs on every shot. Remember you are shooting a projectile that weighs just over 120 grains traveling over 1,300 feet per second. You are dealing on a micro, not macro scale. When you are trying to obtain superior accuracy, you must keep the parameters constant or it will negatively influence accuracy. Again, working on a micro scale, if each bullet has a 2 to 5-grain difference then the balance of the bullet and the actual flight trajectory will be influenced differently per shot. It might not be a large difference but when you are trying for pure accuracy you can see the difference on the target. For comparison, it would be like throwing a golf ball and a baseball with the same amount of force. They will both go a good distance but will not land at the same spot with the same consistency as throwing multiple of one of the balls. <\/p>\n\n\n\n

On my scale, I weighed the 20 bullets. Four bullets weighed 123.9 grains, three bullets weighed 124.0, nine bullets weighed 124.1, and 3 bullets weighed 124.2. That is a spread of .3 of a grain overall. Better than acceptable as far as I am concerned.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"Bullets<\/a><\/figure><\/div>\n\n\n\n

Next, I loaded these bullets on my Mark 7 Auto Drive. The actual load is: RMR\u2019s 9mm (.3555) 124-grain bullet seated in a Starline 38 Super Comp case with CCI small pistol primers and fueled by Hodgdon CFE Pistol. The average velocity is 1390 ft.\/s across my Chrono. Overall length is 1.235 with a .378 crimp (.378 is a .002 crimp on a .355 with a Super Comp case).<\/p>\n\n\n\n

When handloading, be careful of overcrimping as you can change the shape of the bullet, damage it, and cause malfunctions. <\/p>\n\n\n\n

Performance<\/h2>\n\n\n\n

For the test, I will use my Team Infinity IMM Open Gun with a Cmore RTS2-6 minute red dot sight. To begin my test I always load and shoot the first chambered round into the backstop, not on the target. The reason for this is that I want my semi-auto pistol to return to battery in the exact same manner it does during normal cycling. Hand cycling the first round does not create the same type of battery lock up. This is a bullet test, not a gun test, so I want to maintain the same parameter for each shot. I am using a standard pistol rest and sandbag. My target is at 22 yards and each group is five shots.<\/p>\n\n\n\n

First Group:<\/h2>\n\n\n\n

<\/figcaption><\/figure>\n\n\n\n

Second Group:<\/h2>\n\n\n\n
\"Bullets
I adjusted my sight to the left and down. Maybe my nerves settled or I was a little more controlled but I produced a tighter group <\/figcaption><\/figure>\n\n\n\n

<\/p>\n\n\n\n

The last picture is a day later (overcast) when I tried a different Infinity Open gun and a different powder but still maintained the same velocity:<\/p>\n\n\n\n

\"Bullets<\/figure>\n\n\n\n

<\/p>\n\n\n\n

As we can see the RMR 9mm 124 JHP\u2019s produced exceptional results. I have tested many different bullets out of my Infinity so I know what my gun is capable of. This company from Idaho has outdone themselves. To create a bullet that has such consistency and at a price like this is commendable.<\/p>\n\n\n\n

Now some people will say that it\u2019s a pistol and it doesn\u2019t matter or that exceptional accuracy like that is really never needed. I could not disagree with them more. I have seen time and time again where people say the phrase, \u201cit\u2019s good enough.” I was never taught to accept mediocrity or subpar results. I was taught if you\u2019re going to do something, do it right. In regards to reloading, it is not 1% more difficult to do it the right way versus doing it the wrong way. Reloading is based on knowledge and experience. And if you use the provided resources properly there is no reason that your end product cannot be match grade. I have had matches that have come down to the wire. I have had matches that I lost by just a few points on 1,400 + point matches. If I had scored just a few points better on ONE of the 100+ targets we shoot, I would have been the winner. If I would\u2019ve had one solid hit instead of an edge hit on the steel target, again I would have been the winner. If I missed a high point scoring line on the target buy just a millimeter potentially because of inaccuracy then there is the difference between winning and losing. So please don\u2019t anyone ever tell you that, \u201cit\u2019s good enough\u201d. Reloading right versus wrong takes the same amount of effort. <\/p>\n\n\n\n

Price<\/h2>\n\n\n\n

So now let\u2019s talk about that part that I deferred to the end of my review. Price. We can clearly see that these bullets have exceptional performance but the price is what really sets them apart. First, RMR includes shipping in all their prices and at $99 per 1,000 for premium hollow points, RMR clearly has the consumer in mind. They even offer bulk quantity discounts right on their website. If you don\u2019t need a premium hollow point, they also make regular 9mm FMJ with the same tight tolerances starting at $79 per 1000. I can tell you from experience that quantity will excel your learning curve but without quality, you\u2019re just pulling the trigger hoping for good results. There is no hoping with RMR bullets. As a professional shooter, there is no better feeling than knowing for sure you aren\u2019t ever wasting a single shot.  That your groups are as good as they could possibly be and that your misses are 100% your fault and not an ammo or gear issue. 
<\/p>\n\n\n\n

\"Bullets<\/a><\/figure>\n\n\n\n

I have been through many trials and errors. I believe I have gained some knowledge from these experiences. Some were good, some bad, and some just frustrating. But I can honestly say that my experience with these bullets has been positive and shooters will benefit and really enjoy their match performance. I know I have during competition. 

Shoot strong and shoot safe.
