User Tips

Choke Matching:
Test your shotgun’s choke with this load at typical engagement distances to understand how shot distribution and point-of-impact behave — this helps optimize performance for your shooting style.

Pellet Choice:
Match pellet number (e.g., #04 for larger birds vs #8–#10 for smaller game) based on intended game and range expectations.

Range Familiarization:
Spend a few rounds on the range before field use to confirm you’re getting the patterns and energy you expect from this Bior-wad ammunition — muzzle velocity and spread can vary slightly with choke and barrel length.
