Usage and Practical Shooting Tips
The Lethal 405 HD is designed for users who demand precision. Thanks to the Anti-Dry Fire safety mechanism, the crossbow will not fire unless a bolt is properly loaded, protecting the limbs and string from catastrophic failure. Before your first shot, ensure all screws are tight, as vibrations from shipping can sometimes loosen them slightly. Always use the included sled rope cocker to ensure the string is pulled back symmetrically. For those looking for an even easier experience, this crossbow is crank compatible. You can quickly attach the Compact DSC™ Wide 1.5 Sled Crank (not included) to cock the 210 lb draw weight with minimal effort.
Care and Maintenance
To keep your crossbow in top shape for years to come, regular maintenance is essential. Lubricate the flight rail frequently and wax the string and cables every few dozen shots to prevent friction-induced wear and fraying. After shooting in wet conditions, wipe the crossbow dry and apply a light coat of oil to metal parts to prevent corrosion. Safety Warning: Never fire the crossbow with damaged bolts or bolts that are lighter than recommended. The excess energy can damage the limbs. Also, avoid leaving the crossbow in extreme heat (such as a hot car), as this can weaken the composite materials in the limbs.
Recommended Bolt Parameters
For optimal performance and safety, use bolts with the following specifications:
- Bolt Length: 20 inches
- Total Weight: 370–390 grains (including point)
- Nock Type: Killer Instinct V-Track nock or standard Moon Nock
- Material: High-modulus carbon (stiffness is critical for speeds over 400 FPS)
Recommended Accessories
To enhance your shooting experience, we recommend a padded crossbow case for safe transport. Additionally, always keep string wax and rail lube in your gear bag. A high-quality discharge target is also vital for safely uncocking the bow after a hunt. For those hunting big game, the Killertech™ Broadheads are the perfect match, designed to fly with the same precision as your field points.
