Hi Simon,
Bows as in bow and arrows?
Chapter 2 of OHSW should have this in it but it doesn't. A good reference website to the publication
is:
Dark ages OHSW version rules blog
The author is releasing this on October 30th
One Hour Ancient & Medieval Skirmish Wargames
The link is my Amazon Affiliate Account. I'll get a few cents if you buy it. The book is released on October 30th, meaning you would have a first edition.
As an alternative to the book:
Here's what I got when I asked my ChatGPT the question:
Bow and Crossbow Rules for 28mm and 15mm Miniatures
1. Ranges and Accuracy
Bow:
28mm Miniatures: The effective range is 8 inches, while the maximum range is 16 inches.
15mm Miniatures: The effective range is 4 inches, with a maximum range of 8 inches.
Accuracy Penalty: Shots taken at maximum range have a -1 penalty to the accuracy roll.
Crossbow:
28mm Miniatures: Effective range is 12 inches, and maximum range is 20 inches.
15mm Miniatures: Effective range is 6 inches, with a maximum range of 10 inches.
Accuracy Penalty: Like the bow, shots taken at maximum range for the crossbow also receive a -1 accuracy penalty.
2. Cover Modifiers
Partial Cover: -1 to the accuracy roll.
Heavy Cover: For walls, dense foliage, or other significant obstacles, apply a -2 accuracy penalty.
3. Reloading Mechanics
Bow: Rapid-firing allows a shot every turn without reloading delays.
Crossbow: Requires one full turn to reload after each shot, reflecting its longer reload time.
4. Damage Modifiers by Distance
Within Effective Range: Standard roll for full damage.
At Maximum Range: Apply a -1 modifier to the damage roll to reflect the reduced impact due to longer distance.
