Berry s Manufacturing TMJSP Features The Berry s Mfg Superior Plated TMJSP bullet uses a plated jacketed lead construction that seals the lead core inside a copper plating which keeps exposed lead out of the bore and reduces the fouling that bare lead projectiles leave behind. At .308 inches in diameter and 180 grains this bullet is sized specifically for the .300 AAC Blackout cartridge giving reloaders a projectile matched to one of the most popular modern rifle calibers for suppressed and home defense builds. The 1 500 feet per second maximum velocity rating reflects the plated jacket s limits compared to a traditional jacketed bullet so reloaders should stay within that ceiling when developing loads. This construction method keeps manufacturing costs down letting Berry s pass the savings on to the hand loader without compromising the bullet s structural integrity at its rated velocity. Because plated bullets like this one do not require the same crimping and seating precision as fully jacketed projectiles they are forgiving for reloaders still refining their process on a press. The 200 count box gives hand loaders enough projectiles to work up multiple load combinations or to stock up for a full reloading session without running short. Berry s built this bullet as a direct affordable answer to the rising popularity of the .300 AAC Blackout platform among AR-15 shooters running suppressed or short-barreled rifles. For reloaders focused on economical range ammunition rather than maximum velocity hunting or match loads this Superior Plated TMJSP bullet offers a dependable budget-friendly option.
