Choosing Arrows and Broadheads for Your Bow
November 6, 2026 · 1 min read · Antler River Archery

Your arrow is the only part of your setup that touches the deer. Getting it right means tighter groups and better penetration.
Start with spine. Spine is how much an arrow bends when shot. It depends on your draw weight, draw length and point weight. Too weak or too stiff, and arrows fly erratically, especially with broadheads. A 340 spine suits many 60–70 lb setups, but your exact numbers decide it.
Total arrow weight. For whitetails, 400–450 grains is a good target. Heavier arrows carry more momentum and are quieter. Lighter arrows shoot flatter. Most hunters do well in the middle. FOC (front of centre). More weight up front helps arrows fly straight and penetrate. Heavier inserts or 125-grain heads are an easy way to add it.
Fixed blade vs mechanical broadheads.
- Fixed blade: tough, reliable and great penetration. May need extra tuning to fly like field points.
- Mechanical: fly like field points and cut a big hole, but use some energy opening. Best with faster bows and crossbows.
Whichever you choose, check the minimum broadhead rules in the Ontario Hunting Regulations Summary and shoot your broadheads before season.
