Berrien, I won the five stand 10 ga. hammer gun event at the Medford shoot in 2016 with a 21/25 using black powder loads. This year I used the Greener also with black powder and lost by 1 clay. I should have used the Abbey! Lesson learned and the Abbey will be in competition in 2018. It just handles so lively. One does have to accept a few misses on the 2'nd target when blowing a 4 & 1/4 dram load of 7.5's out the tubes and losing a few in the prodigious smoke cloud. But it truly pleases the onlooker's! The gun is being well cared for.
