" 2 1/2" groups @ 100yds with the Brenneke slugs were also the norm."
You might consider bringing that to our next PD hunt.......... leave that ugly black thing at the house.
Ed, i was pleasantly surprised with the accuracy from the Brenneke KO slugs in my smooth-bore A-5 Browning barrel, and it chronoed at near 1600 fps, a 1 ounce slug with that kind of speed and accuracy would be perfect for a 24HCF Boar hunt.
