Apache Junction, AZ –-( In the last number of years there have been a number of companies started up to produce ammo.

Some are niche companies while others supply most modern ammo. One such company is Double Tap.

It was started in 2002 by Mike Mcnett with the idea of producing high quality ammo for hunting and self defense purposes. They are located in Cedar City Utah and have a toll free number 866-867-1066. For info on their products you can go to to view their extensive line of products.

They started out with three loads for the 10 mm but now offer over 300 loadings in various rifle and handgun calibers. They are adding new products all of the time so it is necessary to check their site frequently lest you miss out on something you might want.

I became aware of this company at the writer’s shoot, called Media Day at the Range, which is a day prior to the firearms industry yearly convention known as SHOT show. I talked to Mike and looked over his ammo and it became obvious that he cares deeply about the quality of his products.

Since then I have shot a good amount of his ammo, and I was curious as to who developed the loads they use. It turns out that Mike does all of the load development for Double Tap. That job requires a lot of knowledge about ballistics and loading not to mention the time involved . Since his ammo shoots so well I can appreciate the dedication he puts into developing his products.

They also sell some accessories including some brass and bullets so that might be something to look into.

A couple of weeks after the SHOT show was over he sent me some sample ammo in 380, 9mm and 40 caliber. He uses premium bullets from such makers as Barnes Hornady and Nosler all top notch. He buys brass from various makers and it is always top grade. A couple of loads have a high ES but that could be a function of that individual gun. Every gun is different and some don’t like a certain load or bullet. That is why it is important to experiment with your firearm to see what it likes.


  • 9 mm Beretta 92 5” – 124 grain – 1293 – consistent
  • 40 Glock 22 5” – 125 grain Barnes – 1308 – very consistent
  • 40 Glock 22 5” – 200 grain Nosler – 1013 – nice
  • 40 Glock 27 3 &1/2” – 125 grain Barnes – 1257 – OK
  • 40 Glock 27 3 &1/2” – 200 grain Nosler – 976 – consistent
  • Sig 220 5” barrel – 160 grain Barnes Tac XP – 1132 – potent
  • Sig 220 5” barrel – 185 grain Nosler – 1199 – nice
  • Rock River 308 20’ – 150 grain Barnes TTSX – 2875 – consistent
  • Rock River 308 20” – 180 grain Nosler Accubond – 2588 – good load
  • Rock River 308 20” – 200 grain Nosler Accubond – 2443 – high es
  • H & R Pistol 32 mag – 60 grain Barnes 2 &1/2” barrel – 1058 – consistent
  • Ruger 327 mag 5 & ½” – 60 grain Barnes – 1581 – impressive

We shot the 60 grain Barnes in the 327 ( read my review of the Ruger Blackhawk Revolver In .327 Fed. Mag.) at 25 yards and they were very accurate. A better rest & less wind would have done better. I have also shot some of his ammo in a couple of Diamondback pistols that I was testing out. They are very sub compact models and they performed well with his ammo. Calibers were the 380 and 9 mm. Accuracy for such small pistols was outstanding. Neither gun jammed with this ammo.

Double Tap 45 Ammo
Double Tap 45 Ammo used to test with Ruger Commander worked very well.

The Rock River 308 Rifle shot the Double Tap very well at 100 yards giving groups in the 1” area consistently. Both the Barnes and Nosler Accubonds shot well indicating good quality ammo. Either bullet would be suitable for large game hunting since there were no feeding issues..

The 45 Auto Rim came out during WW1 to supplement the 45 ACP. It is used in Colt and S & W large frame revolvers. I have a S & W 1917 which I used to test the Double Tap load. As usual it performed well. That is a potent load but they have several others in the auto rim caliber.


  • Double Tap – 255 gr SWC – 769 – potent

I recently received a Ruger 45 auto with a 4 &1/4” barrel for T & E. I thought that Doubletap ammo would work well and I was right.

The Commander digested everything that I fed it. For personal protection the Nosler 185 grain load would be hard to beat and I plan on using it as my carry load.


  • Double Tap 185 gr – Nosler HP – 1182 – potent
  • Double Tap 200 gr – Bonded JHP – 1089 – consistent
  • Double Tap 230 gr – FMJ RN – 883 – nice

I have a LAR Grizzly in 45 Win mag. There were several guns made for this caliber though the Grizzly and the Wildey were discontinued. TC makes a barrel and Freedom Arms offers an optional cylinder for their model 83. Factory ammo is difficult to find unless you check with Double Tap. They make four loads for it so you are in luck if you are lucky enough to own one of these pistols. I started shooting ammo in this gun but unfortunately, the ejector broke so test was cancelled. The Double Tap look good with the limited shooting I did.

If you need 45 Win Mag ammo for your LAR Grizzly look no further Double Tap has in stock.

Up to a few years ago when S & W introduced the 500 the 454 Casull was the most powerful commercial handgun. With good loads it is capable of taking any big game. Double Tap makes some loads for it and they shot very well in my Freedom Arms model 83 with a 10” barrel. Recoil with the 400 grain can be only described as brutal.


  • Double Tap 400 Gr – WEN-GC – 1280 – Impressive
  • Double Tap 250 Gr – Barnes HP – 1621 – Accurate

Recently I had a chance to visit and tour his factory in Cedar City Utah. While the operation doesn’t look large the available space is utilized in an efficient way. They use a number of Dillon presses to manufacture most of the ammo. The Dillon presses are set up for production while maintaining the high quality control that Mike demands. For the most part he uses Starline brass which is also a quality product though other brands are utilized.

Bullets come from various manufactures such as Barnes, Nosler and Hornady. The rifle ammo is hand crimped in a single stage RCBS press and individually inspected by the operator. Mike has opened a new facility near the old one because of the rapid growth he is experiencing.

After shooting a lot of Double Tap ammo and have never had any type of problem. There are several ways to measure ammo quality. First of all it has to be safe and fit and feed in the gun it is designed for. Next it has to be consistent in order to be accurate. Consistency is usually measured by a chronograph, which measures its velocities among other factors. If it has a low standard deviation and ES, the difference between the slowest and fastest shot in the string, then that is an indication of good quality. Among other things it requires the proper powder and amount the amount to use, which takes some experimenting and time to develop such loads. It also has to be safe in the guns that it is designed for.

Consistent ammo, that is also accurate, is an important consideration both in hunting and self defense. Mike puts the velocity on all of his product boxes and the guns that were used to develop the loads. If your gun is similar to his then you should get similar results. I have shot a good amount of his fodder and the velocities are always very close to the advertised speed.

I’m here to tell you that his ammo meets all of the criteria necessary to call it great ammo.

Based on my experiences with it I would recommend his ammo without hesitation. I don’t see how his business would ever fail with the quality products and service he offers.

My son and I have fired 10mm ammo out of our Glock model 40, and the ammo functions fine. Very potent and accurate ammo. We just received our order of 40cal and 9mm+P ammo. Good looking ammo. Very fine work. Thanks Doubletap for offering good quality ammo at a good price.

I purchased a box of your 165 gr Nosler cartridges at the Canadian tire store on Shawville, Qc. I went online and was quite impressed with the reviews. I headed to the firing range fired a first round with my Browning BLR – the spent casing was jammed solid in the chamber and was removed using quite a bit of force. I proceeded with another round and same scenario. I had to invert my rifle and grab the lever with a pistol grip to extract the casing. I feared that I damaged the extractor in the process. I fired half… Read more »

I was hoping to see some tests with a 30-06 spring field 180gr with the black polli tip

Question. I have a new Glock 20 gen 4 and want to know if your 200 grain ammo will work with this gun. Saw

I needed some Weatherby 257 lead free ammo. DT was out according to their website. I wasn’t sure if they still made it or not so I emailed them. They got back to me the next day and asked how much I needed. In less then 10 days it was on my porch. BTW it was 4 boxes, not very much and they still did it for me. Amazing service!

Last year I was trying to purchase some .264 rifle ammo and they had stopped production. Mike took the time to email me and let me know he might possible have some but would have to check. I later got a call from Mike and they had found some remaining material to load me some. I bought all they had at the time. I highly recommend Double Tap and I will not bu from anyone else.


I ordered 1 box of 450smc on the 17th, got a tracking # on the 20th, but come the 23rd, still no package. I call UPS, but they have no shipping info. So I call Double tap, and get a get ” matter of fact “oh, that hasnt shipped, your order is going out the end of next week.” Wow! So $28 for a box of 20 rounds, but over $13 in shipping…..and I won’t get my order, which was supposed to be a gift for my son, until over 2 weeks. Hmm, I bet larger orders don’t wait that… Read more »


I have used their ammo and it is good. It seems they need front office help with customer relations. I heard
a promo for free shipping on the radio which involved using a code when ordering. The web site didn’t take the code given on the radio. Good products…..poor ordering dynamics.

I have been stocking up Double Tap Ammo ever since he was in Kearns UT. I have shot his + P ammo but keep it for self defense. A lot of it. Stock up. Buy what you can afford and build up a supply for when the Zombies come after you and your family. You can’t go wrong.

I just purchased a Sig 1911u Ultra Compact. What is your opinion of the use of Doubletap 160 Gr Barnes Mann ammo in this gun. I am primarily concerned about controllable recoil.
