I just got a question from a reader asking if sabots are allowed in Pennsylvania’s second muzzleloader season (which just opened today).
The answer is that in the second muzzleloader season sabots are allowed. There was a time when it was roundball only, but a few years ago they changed it to allow other projectiles. So, this means you can use either projectile. When picking the projectile be sure to match it to your barrel twist for maximum accuracy. Below is quoted from page 45 of the hunting digest.
Flintlock Muzzleloader Season: Flintlock ignition, single-barrellong gun, 44 caliber or larger, or 50 caliber or larger handgun, usingsingle projectile ammunition. It is unlawful to use telescopic sights.Peep sights are permitted.
