What is TSJ Ammo?
Hey all, today we here at True Shot Academy are going to be going over TSJ ammunition today. Ammunition of this type has been increasing in popularity among shooters and reloaders in recent years, particularly in the world of competition. The goal of this blog post is to give a brief overview of TSJ ammunition while also going through some of the traits and features of these loadings. Without further ado, let’s answer the question: “what is TSJ ammo?”
About TSJ Ammo
Rather than utilizing metal jackets, total synthetic jacket, or TSJ loadings feature jackets made from alternative materials. Specifically, synthetic jackets make use of polymers and similar synthetic materials to coat the projectile. TSJ rounds can be had in the form of popular pistol and rifle calibers. Simply put, these loadings lack the metal jacket common on traditional loadings.
Why Use TSJ Ammo?
Like full metal jacket (FMJ) ammo, TSJ ammunition also prevents a raw lead projectile from impacting the lands and grooves of a barrel. Jacketed lead projectiles are also going to feed smoother than exposed lead projectiles. The covered projectiles in both FMJ and TSJ loadings ultimately provide “cleaner” results than their exposed lead projectile counterparts. As TSJ ammunition lacks a traditional metal coating, they eliminate metal-on-metal contact within the bore. The use of a synthetic jacket over a copper jacket prevents lead and copper from being deposited in rifling. Metal-on-metal friction is also eliminated due to the omission of a metal jacket. TSJ rounds also helps to fully contain the lead of the projectile, decreasing the amount of lead and debris after shooting. Essentially, this ammunition runs “cleaner”, is easier on the bore, and decreases the amount of lead a shooter will be exposed to.

Who Makes TSJ Ammo?
As it is relatively new on the scene, TSJ ammunition is manufactured by a handful of companies. Notable providers of loadings of this type are Federal and Jello Shots. Most of the TSJ ammunition on the market will be handgun ammunition loaded to various specs. Common offerings include 9mm Luger, .40 Smith & Wesson, and .45 ACP loadings. For example, Jello Shots makes subsonic and competition oriented TSJ ammunition. Federal’s Syntech ammunition is offered in different lines such as their Action Pistol, PCC, and Range loadings. At the end of the day, this type of ammunition has official support from viable and well-known companies.
How Available is TSJ Ammo?
While TSJ type ammunition is outnumbered by traditional loadings, it is still somewhat available on the market. One will encounter loadings produced by companies such as Federal and Jello Shots which represent TSJ ammunition. At the end of the day, one can find TSJ ammunition or load it themselves if they wanted to.
TSJ Projectiles
Like other reloading components, one can find TSJ projectiles available for sale. The most notable provider of TSJ type projectiles is The Blue Bullets, a company which supports a variety of calibers. The Blue Bullets in particular supplies loadings .300 Blackout, .308 Winchester, 9mm Luger, and .45 ACP to name a few. Essentially, a prospect reloader can find TSJ projectiles in both pistol and rifle form.
Is TSJ Ammo Affordable?
As mentioned above, one can purchase TSJ projectiles and roll their own ammunition. If a reloader has an established setup with healthy supply of components, one can produce their own TSJ ammunition for relatively cheap. When it comes to purchasing TSJ ammunition, one will find they are generally more expensive than their counterparts. The increased cost associated with TSJ ammunition can mainly be chalked up to the application of the synthetic jacket as it is a newer practice which departs from the norm.

TSJ Ammo for Self-Defense?
It should be known that all ammunition is lethal, including TSJ ammunition. Federal offers Syntech Defense loadings for popular pistol cartridges such as 9mm Luger and .45 ACP. These loadings in particular feature segmented hollow point projectiles with a synthetic coating. It should also be known that these TSJ options exist alongside more traditional and established types of jacketed hollow point (JHP) offerings. When considering a potential self-defense load, one should consider multiple options and ensure they function in their carry gun.
Conclusion
At the end of the day, TSJ ammunition is a viable choice for a variety of shooters. Whether you’re shooting competition, training, or simply want to shoot “cleaner” ammunition, TSJ loadings have you covered.
