Ive never been a shotgunner (raised to aim deliberately with a .22) but have ended up with a few 'just in case'. But those 12s are not very pleasant for me, even with the recoil pad buttstock I put on an old model Partner, and trap rather than field loads, so Ive not done much with them.
As it is, a 20ga. barrel came along that fits the 12s frame and is it ever a delight with the 1oz #6 loads Ive been using.
Now I understand what you all where sayin'!
