Playing with the 870
Installed an extension tube on the 870 and took it out to make sure it worked and fed right 18" open choke. I do believe this could be used as a bird gun up to around 40 yd. I patterned some estate 1.25 oz 8's and it done fairly well. At 35 yd it really saturated. Tried a remington 1 oz slug at 60yd and it was about 3" below point of hold. Not too bad for a house gun. Shot an old board at 20' and the 8's left an indentation about 9" across .
