The accutrigger is a huge plus for the 220F! My H&R trigger was heavy out of the box, there is a way to make it lighter and mine is good now. But just the fact that you can easily adjust the savage at home is a plus.. And with that being done it's safe and has no creep..
Have heard of issues with the H&R misfiring, stocks coming loose and scope mounting holes being drilled off center.. With that said the one I bought is fine but I usually check all of that kind of stuff anyway. Mine is really accurate and with a little extra bench time I would not be surprised if it outshot the savage, but it is very close either way and currently the savage has the upper hand on groups.

I feel like the H&R is a really accurate but heavy slug gun that may have a couple issues that are easily overcome. I feel that the savage 220F is a rifle that just happens to shoot 20 ga. slugs.. lol Plus I was able to mount my scope much lower on the savage which is more in my line of sight and more comfortable.. So as you can tell I love both guns but I have to give the upper hand to the savage.. Not because you get an extra slug in the box mag but more for the reasons above..

Good Luck!
