Crossbow Season Prep: A Pre-Season Checklist

Start with the powerplant. A frayed string, a dry serving or worn cables change how the bow behaves shot to shot — and a dry-fire or a failure under load is a safety issue, not just an accuracy one. Before anything else:

• Inspect the full length of the string and cablesfor fraying, separated strands or a worn serving. Anything questionable gets replaced — on the manufacturer's schedule, not "whenever."
• Wax the string with a quality bowstring wax, keeping wax off the serving. A waxed string lasts longer and shoots more consistently.
• Check and lube the rail if your bow uses a flight rail, per the manual.
• Torque-check the hardware— scope rings, rail and limb bolts. A loose mount is a classic cause of mystery flyers.

Transport, temperature swings and a season in storage can all nudge your point of impact. Never assume last year's zero survived the off-season — confirm it. Off a solid rest, shoot a group at 20 yards using the top aiming line, then walk out and verify 30, 40 and 50 yards on the corresponding lines.

If anything is off, follow the full process in our how to sight in a crossbowguide. Remember that on a multi-line speed scope, the distance lines are only accurate when the scope's speed setting matches your bow's actual arrow speed — so if your 20-yard zero is good but the longer lines miss, check the speed setting before you touch the turrets.

Your bow can be perfect and a bad bolt will still throw the shot — or worse, cause a dry-fire. Inspect every arrow you plan to hunt with:

• Flex-test each shaft and retire any that are cracked, splintered or bent. A damaged carbon bolt can fail catastrophically.
• Check every nock for cracks and correct seating. The wrong or damaged nock is a leading cause of dry-fires.
• Confirm bolt length, grain weight and nock typematch your specific crossbow's spec. The wrong bolt is a safety problem, full stop.
• Check the vanes and inserts and re-glue any loose broadhead or field-point inserts.

Broadhead choice is a real decision on a fast crossbow, not an afterthought. The two families each have a genuine trade-off:

• Fixed-blade headsare durable with no moving parts, but they can "plane" (steer off line) on very fast bows — think 400-plus FPS — and are harder to tune to your field-point point of impact.
• Mechanical (expandable) heads fly like field points and open to a wide cut, but they spend some kinetic energy deploying and can open prematurely at high speed. If you shoot a fast crossbow, use only mechanical heads that are specifically rated as high-speed.

Energy is rarely the issue: deer need roughly 40 to 60 ft-lbs of kinetic energy, and modern crossbows in our best crossbows lineuprun well past that. The real limiter is tuning and shot placement — so whichever head you choose, prove it on the target before you trust it in the field.

Practice the way you'll hunt. That means shooting your actual hunting broadheads — not just field points — because fixed blades in particular can print differently. Sight in with field points to save your broadheads, then confirm with the real thing and tune to it, because that's what you'll hunt with.

Be honest about distance. For crossbows, roughly 40 yards is the widely accepted ethical practical maximum; skilled shooters with 300-plus-FPS bows may stretch to 50 or 60 yards. The limiter past 40 isn't energy — it's trajectory and animal movement, including a deer "jumping the string" on the shot. If your groups open up dramatically at distance, that spread is your honest maximum range, not a number to talk yourself past. A compact, fast rig like the Ravin R18makes practice easier because it's light and maneuverable — but even the best bow can't rewrite the ethics of range.

Round out the kit and the safety routine before opening morning:

• Confirm your cocking device (rope cocker or crank) works smoothly and is complete.
• Pack a rangefinder, extra nocks, string wax and the manual's recommended field tools.
• Inspect your treestand, harness and safety line — a full-body harness is non-negotiable, and most stand accidents happen climbing in or out.
• Keep your forearm below the flight deck at all times, never dry-fire, and store the bow uncocked between sits.

A dialed bow still needs to be in the right place at the right time. Whitetails are crepuscular — most active in the first couple of hours after sunrise and the last couple before sunset — so plan your sits around dawn and dusk rather than midday.

Match a ready bow to the right window and you've done everything the off-season can do for you.
