The Armscor Cal 55gr FMJ-BT bullet is a workhorse .224 inch projectile that keeps your high volume reloading affordable without cutting corners. These are brand new, not pulled, 22 caliber bullets for reloading, built as a 55 grain full metal jacket boat tail with a cannelure for a solid crimp. If you feed an AR or a bolt gun in .223 or 5.56 and you shoot a lot, the Armscor Cal 55gr FMJ-BT is exactly the kind of bulk component that keeps you on the range. This is a bullet only, not loaded ammunition, and it is offered in bulk quantities so your cost per round stays low even when the round count climbs. Practice is what builds skill, and skill is a lot cheaper when your components are affordable and consistent. A big box of dependable FMJ bullets is exactly what turns range time into a regular habit rather than an occasional splurge. Load a few hundred at a sitting and you have plenty to run drills, sight in, and simply enjoy your rifle. That is the quiet value of a good bulk bullet on the reloading bench.
What the Armscor Cal 55gr FMJ-BT is and who it is for
This is a classic 55 grain FMJ profile, the bread and butter weight for the .224 bore, offered here in bulk quantities so you can load in volume and pass the savings to yourself. The boat tail base helps the bullet track cleanly and stabilize, while the cannelure gives you a clean, repeatable crimp for reliable feeding in a semi automatic. That combination makes it a natural for high round count practice and plinking.
The Armscor Cal 55gr FMJ-BT is for the AR shooter, the training minded handloader, and anyone who wants to keep their cost per round low. When you shoot hundreds of rounds in a session, a dependable bulk bullet like this is the backbone of your loading bench. It is the kind of component that turns a busy range day into an affordable habit rather than an expensive one.

Specifications woven into your load
At 55 grains the Armscor Cal 55gr FMJ-BT sits right in the sweet spot for the .224 bore, stabilizing easily in common twist rates and delivering flat, predictable trajectories for practice distances. The cannelure lets you crimp with confidence, which matters for feeding reliability and for taming the recoil impulse of a semi automatic action. With bulk 500 and 4000 count options, you can buy exactly as deep as your shooting habit demands.
Because these are new, uniform bullets rather than pulls, your loads stay consistent from the first round to the last of a big batch. That uniformity keeps your point of impact steady across a long training string, so your practice actually reflects how your rifle shoots.
Practical use, care, and compatibility
Load these from published .223 or 5.56 data and set your crimp at the cannelure for reliable feeding, especially in an AR. Confirm your barrel twist stabilizes a 55 grain bullet, which nearly all modern .224 rifles do with ease. Setting a consistent crimp at the cannelure also helps keep bullets from setting back under the feeding cycle of a semi automatic.
Store the bullets boxed and dry, and keep your batches organized so your high volume loading stays orderly. Stock up alongside brass, primers, and storage from the rest of our reloading components and gear. Bullets from Armscor are a component and not a firearm.
