This guide explains how to choose the right products at Tatted Tacticals and how to read the specifications that matter — from ammunition caliber and grain weight to optic footprints, mounting standards, and tactical gear sizing. If you have a question this page does not answer, our team is one message away through the Contact Us page.
How to Read Ammunition Specifications
Every ammunition listing on our site follows a consistent specification format so you can compare loads at a glance. Understanding each field helps you order the correct round the first time.
- Caliber / Cartridge — the dimensional standard of the round (e.g., 9mm Luger, .223 Remington, 6.5 Creedmoor). The caliber must match your firearm’s chambering exactly. A .223 Remington chamber will not safely fire 5.56 NATO in every rifle, and .38 Special is not interchangeable with .357 Magnum in reverse. Always confirm your firearm’s stamped chambering.
- Grain Weight (gr) — the mass of the projectile. Lighter grains (e.g., 55gr in .223) travel faster with flatter trajectories; heavier grains (e.g., 77gr) retain energy downrange and buck wind better. Match grain weight to your barrel’s twist rate for best accuracy.
- Bullet Type — FMJ (full metal jacket) for range and training; JHP (jacketed hollow point) for self-defense; soft point and polymer-tip for hunting; match/OTM for precision. Browse our full ammunition catalog filtered by type.
- Box Count — rounds per box (commonly 20 for rifle, 50 for handgun) and case quantities for bulk buyers. Use our bulk inquiry option for case and pallet pricing.
Choosing the Right Caliber
Caliber selection depends on your intended use. The right round for home defense is rarely the right round for long-range precision or small-game hunting. A few practical starting points:
- Range & Training — affordable FMJ in your firearm’s caliber. For most shooters that means 9mm, .45 ACP, or .223/5.56.
- Self-Defense — quality JHP designed for reliable expansion and appropriate penetration. Popular defensive calibers include 9mm, .40 S&W, and .45 ACP.
- Hunting — match the cartridge to the game and local regulations. .243, .270, .30-06, and 6.5 Creedmoor cover most North American big game.
- Precision & Long Range — match-grade loads in 6.5 Creedmoor, .308 Winchester, or .338 Lapua Magnum, paired with a barrel twist rate suited to the bullet weight.
Before ordering, always verify the caliber is legal to ship to your state. Our State Shipping Restrictions and Ammunition Shipping Compliance pages list every jurisdiction-specific rule.
Optics, Mounts & Fitment
Optic compatibility comes down to two things: the mounting footprint and the platform interface. Getting both right ensures your red dot or scope sits where it should and holds zero.
- Red Dot Footprints — micro red dots use standardized footprints (Trijicon RMR, Docter/Noblex, Shield RMSc, and others). Your slide cut or mounting plate must match the optic’s footprint. Check the product specification before ordering.
- Rail Standards — most rifles and many handguns use the Picatinny (MIL-STD-1913) rail. Weaver rails are similar but not always cross-compatible. Confirm slot spacing if you are reusing an existing mount.
- MOA vs. MIL — reticle and turret adjustment units. Choose one system and stay consistent across your optics so holdovers and adjustments translate cleanly between rifles.
- Ring & Mount Height — scope objective diameter and your cheek weld determine ring height. A larger objective needs taller rings for barrel clearance.
Trigger & Platform Compatibility
Drop-in triggers are built to platform standards. Before ordering from our Super Safety Trigger or Binary Trigger categories, confirm three things:
- Platform fit — most aftermarket triggers are cut for mil-spec AR-15 / AR-10 lower receivers with standard 0.154″ pin holes. Verify your lower is mil-spec, not a proprietary pattern.
- Legal status in your state — advanced trigger systems including binary triggers are restricted or prohibited in certain states. It is your responsibility to verify current legality before ordering. We do not ship prohibited devices to restricted states.
- Safe installation — always confirm your firearm is unloaded before any work. Review the Four Rules of Gun Safety and our Firearms Safety Guide before installing any fire-control component.
Magazine & Capacity Notes
Magazine compatibility is platform- and caliber-specific. A magazine must match both the firearm pattern (e.g., AR-15, Glock, AK) and the cartridge. Several states impose magazine capacity limits — check our State Shipping Restrictions page, as we apply capacity rules automatically based on your shipping address at checkout.
Tactical Gear & Apparel Sizing
For wearable gear — plate carriers, belts, holsters, and branded apparel — use the sizing chart shown on each product page. General guidance:
- Holsters — sized to the specific firearm make, model, and (where applicable) whether a light or optic is mounted. Order to your exact configuration.
- Belts — measure through the belt loops you actually wear, not your pant size; gun belts run differently from dress belts.
- Plate carriers & apparel — follow the chest/waist measurements on the product page rather than assuming your usual size, as cut varies by manufacturer.
