.308 WIN 180gr TCX (Total Copper X-panding) Subsonic Ammunition
Built with Lapua brass casings, the TCX308 180gr is a 180 grain, .308 Winchester caliber Total Copper X-panding round, with a muzzle velocity of 1,000 feet per second and 400 ft/lbs of muzzle energy, as tested in a 16 inch,1 in 10 twist barrel.
Packaged 20 rounds per box, we build these to our exacting standards to ensure you have only the most consistent and reliable defensive ammo available.
DEFIANT MUNITIONS uses only the highest quality primers, powder, brass casings and projectiles in all of our Premium Defensive ammunition.
TCX (Total Copper X-panding) ammunition incorporates a 100% solid copper projectile, with both interior and exterior serrations to ensure maximum expansion.
There is no bi-metallic bonding to separate or otherwise fail, as can occur with JHP (Jacketed HollowPoint) projectiles. The result is consistent penetration that meets or exceeds FBI standards, and expansion that reliably outperforms typical JHP (Jacketed HollowPoint) projectiles.
At DEFIANT MUNITIONS, we don’t simply test each new product upon release. We test every lot of ammunition for pressure, muzzle velocity, muzzle energy, penetration depth, expansion rate and weight retention to the highest standards. We go the extra mile to ensure maximum performance and consistency. Additionally, every round is inspected and chamber checked by hand before packaging.
**Notice to customers: Due to the subsonic nature of this load, it is NOT designed to properly cycle a semi-automatic or automatic firearm. It may be necessary to single feed each round in semi-automatic and automatic firearms.

The Defiant subsonic 308 TCX-S is the gold standard in repeatability creating my confidence in the round. I use the round to deer hunt at a relatively close range in a heavily forested area through a suppressed rifle to shoot deer. Due to the aimpoint, the round must rapidly expand creating a large wound channel with as many ft/#'s as can be generated. Deer must be DRT. The round has to be accurate and consistent for my needs and this is the best subsonic I've tried. I've shared with friends and had 100% feedback from a friend shooting hogs at night through his suppressed rifle. QUALITY components. Peter Pi, Jr. stands behind his name and has created the perfect round for my needs. Yes - Five Star rating.
I am over joyed with how theses rounds preform!!!! They are Quiet a yet devastating for varmints an whitetail !!!! I will be purchasing more in the future!!!!!!!! Keep up the great work
I love these .308 subs for hogs. But really, the best part is Defiant ships quickly. 2nd time I've ordered from DM and both times they've been awesome.
I am in love with this ammo. When u can shoot a mature 8 pointer and the ammo goes through both shoulders I mean what more can u ask for. I will only buy this ammo thank u for such a excellent bullet
Only used enough to sight in and check accuracy. But it is very good at 100yds. Sub 3/4”. Looking forward to trying it game hunting. No supersonic hot loads so far that you normally see in bulk subsonic ammo. Looking forward to seeing what it can do on an animal. Price is steep but understandable with the all copper tcx bullets. Customer service I received was far and above anywhere else. I’ll be buying more!
