Lots of good stuff already said. I went through this a dozen years ago with some similar problems. I found reasonable results by trying 1 box of each of every brand/size/ make/ect. I found some of the magnums kick like a mule but don't always group nice, seems like more powder just spreads it out more. Best results were from non-magnums, but there was a big difference from brand to brand. I don't remember the grouping, but there is not good results past 25 or 30 yards. Buckshot is for close-up stuff.
I had much the same results with slugs, some brands really good groups at 75 yards, others not, the magnums were less performing than non-magnums. You simply have to try a bunch and see what works best in your gun.
If I need bear repellent, I load four 1oz slugs followed by two .000 magnum buckshot. If I still have to fire the buckshot, its cuz I'm next to screwed.
