Hornady (www.hornady.com) is probably best known for their bullets and reloading tools. However, they also market a line of useful cleaning and lubricating products. Three of these with which I have extensive experience are their One Shot Gun Cleaner with Dyna Glide Plus, One Shot TAP HD-Extreme and Spray Case Lube.

One Shot Gun Cleaner with Dyna Glide Plus

I have been using this product for over a decade and it has never let me down. The can is labeled "Gun Cleaner and Dry Lube," which well describes its capabilities. I use it routinely for quick cleaning and lubing of gun bores and actions, and for wiping off and protecting barrels and receivers.

For instance, One Shot and a Hoppe's Bore Snake have become my sole tools for routine maintenance of my Ruger 10/22 rifles. To clean a bore, I make three passes with the Bore Snake. For the first pass, I spray One Shot on the bristle area of the Bore Snake and draw it through the barrel. I make a second pass with the Bore Snake dry and then a third pass with One Shot sprayed on the tail of the snake. Result: a clean bore every time.

To clean a 10/22 action, I spray a liberal dose of One Shot into all parts of the receiver, including around the bolt, into accessible areas of the trigger group and on the magazine release mechanism. I cycle the bolt a few times, wipe any residue off with a paper towel and call it done. I have not had to remove the bolt or trigger group for a more in-depth cleaning in years.

The 10/22 rotary magazines get the One Shot treatment, too. Whenever needed, I spray it into a magazine, shake the mag around a bit, then shake out and wipe off any residue. This keeps the mags running smoothly.

Finally, I spray some One Shot on a paper towel and wipe it on the barrel and receiver. This both cleans the metal and leaves a dry protective coating. If there is an easier way than this to maintain a .22 rimfire rifle, I want to hear about it.

This product comes in five and 10 ounce spray cans. I always carry a five ounce can in my range bag and have a 10 ounce can on my workbench. The five ounce can (SKU 9990) has a MSRP of $11.17, while the 10-ounce (SKU 99901) MSRP is $17.79.

One Shot TAP HD-Extreme

TAP HD is an enhanced version of the cleaner/dry lube discussed above. Anyone who wants to know the differences can read the product descriptions on the Hornady website, so I will not get into that here.

I use TAP HD mainly to keep my autoloading pistols and revolvers running well. Over the years I have tried various greases, oils and sprays to keep autoloader slides and revolver cylinders running free. TAP HD is better than anything else I have used.

The abiding issue with using grease or oil to keep a handgun running is that both collect shooting residue, which necessitates frequent cleaning and relubrication. I find that this problem is greatly lessened when I use TAP HD. I spray it on the action springs and rails of autoloaders and around the cylinder axles of revolvers and they run free for extended periods without collecting much residue.

I also use the TAP HD for general handgun maintenance, including cleaning and lubricating firing mechanisms and magazines. It works well on the outside of autoloader barrels and as a cleaner/protectant on all handgun metal surfaces, internal and external. It will serve for basic bore cleaning, too, used with a Bore Snake or a cleaning rod and patches. TAP HD comes in five ounce spray cans (SKU 99936) at a MSRP of $12.55.

Other Uses

I also use these products for general cleaning and protection of centerfire rifles and shotguns. I have quit using gun oil on barrels and receivers, since either of these One Shot products does a better job of protecting the metal than oil, with no dirt-collecting film. I also use them to clean and lubricate the bolts and raceways of my bolt action rifles, along with the actions of lever rifles and pump shotguns.

If I expect that I might need to do a basic bore cleaning of a rifle or shotgun at the range or in the field, I take along the appropriate Bore Snake or cleaning rod, jags, patches and use them with One Shot to do a quick job.

However, I do not recommend using One Shot as the sole solvent for cleaning the bores of centerfire rifles, handguns and shotguns. This is because One Shot is not designed to break down heavy copper or lead fouling in barrels, which may be expected to occur with shooting high velocity or high pressure ammunition. The same goes for plastic shot cup fouling in the bores of shotguns. When significant copper, lead, or plastic fouling is an issue, use bore cleaning solvents designed to deal with these.

Spray Case Lube

Hornady One Shot Spray Case Lube is designed for use when resizing bottlenecked cartridge cases for reloading. In my experience, it is a very desirable alternative to sizing waxes or creams that must be manually applied case by case, because it is quicker, less messy and more consistent in performance.

To use the Spray Case Lube, I start with cases that have been deprimed and cleaned in a vibrating case cleaner. I place them in a shallow loading block, which I set on some wrapping paper or butcher paper to catch overspray. I shake the can of case lube very thoroughly. Then, I spray it lightly over all sides of the block of cases, holding the can somewhat above the level of the cases and angling the spray downward so that some will get on the inside of the case mouths, as well as uniformly around the outsides of the cases.

After spraying, I let the cases dry for five to 10 minutes and then resize them. I am not a truly high volume reloader, but my records show that I have loaded over 2000 rounds total of .223 Remington, .260 Remington, .308 Winchester and 8x57 Mauser ammo using this sizing method. I have not had a single instance of a stuck case, dented case shoulder, or deformed case neck. I use a RCBS X-Die for the .223 Remington and Lee dies for the other calibers.

Besides the ease of application and trouble free results I have had with the Spray Case Lube, I also like it because there is no need for post-sizing cleanup. This is not true if one uses a wax or cream sizing lube, for the cases must be wiped individually or run through a vibrating case cleaner to remove the residue on them.

Some people swear by this product, while others swear at it. Obviously I fall into the first group. I do two things when using the Hornady One Shot Spray Case Lube that I believe help avoid some of the problems that others have claimed they encountered. First, I use just enough lube to get a light, even coverage all around the case bodies, but I carefully avoid dousing them.

Second, I make sure that the inside of my die is clean before I begin resizing a batch of cases and then I clean it again when I have finished. With what do I pre- and post-clean my sizing dies? Hornady One Shot Gun Cleaner and Dry Lube, of course. Hornady One Shot Spray Case Lube comes in five ounce cans (SKU 9991), with a MSRP of $11.17.


I have found these three products very useful in the indicated applications. If you have not tried them, I suggest that they are worth at least one shot.
