Full Metal Jacket Truncated Cone (FMJ-TC) Bullets Explained
A full metal jacket truncated cone bullet is a lot like the name implies. You’re going to get a bullet with a cone shaped nose with the end cut off so it’s got a flat tip at the end. This type of bullet lies between the standard FMJ and the FMJ-FN and is mostly used for target shooting and competitive matches. These are good for scoring because they leave a very nice round hole in paper making it less likely you end up with disputed scores you can get with round or pointed tips. The full metal jacket truncated cone can either be partially or fully surrounded by a harder metal such as copper or a composite.
Advantages of FMJ-TC
Some target shooters and competitive shooters find they get a bit more accuracy with TC bullets compared to flat tip at longer ranges but this can depend a lot on the skill of the shooter and the gun. The design of the truncated cone helps ensure reliable feeding in semi-auto pistols when compared to other designs such as the semiwadcutter hollow point. Finally, the fully jacketed bullet can help to reduce the amount of lead exposure for the shooter and those in the area.
Disadvantages of FMJ-TC
As with any FMJ, there’s certain places you won’t be able to shoot these and even if they’re designed to hunt, you can still get in trouble hunting with them. While they have less penetration than boat tails or standard bullets, they can still go through a target and negatively impact whatever is behind it. A lot of hunting areas have a zero tolerance policy for FMJ bullets of any type so make sure you check before you head out or bring a couple ammo types along just in case. The bullet itself is not the best choice for home and personal defense, this is because of the increased risk of overpenetration as the bullet is not designed to expand on impact.
This type of bullet is pretty popular overall and is the best of both worlds to some. It’s more aerodynamic and accurate than a flat tip but not quite like a boat tail. The lack of exposed lead can be a perk with some brands that fully cover it and lots of ranges don’t mind exposed lead at the rear of the bullet.
