I have that same rifle in 22 mag and mine shoots the same way. The 30 gr Hornady ammo is best but not by much because it is a genuine 1" 5 shot group gun @ 100 yds also. I bought a 10 rnd magazine for mine right after I got it. My rifle chronographs a flat 2000 fps with Federal 40 gr! That's cooking! I also have a Marlin 25m that shoots just as well after I glass bedded it.
As far as the reputation for being inaccurate, I cant buy it. I have to think that it was the rifle or shooters fault and not the round it's self. My son's 9422 Win is a pretty close to a 1" gun but you really have to bear down to make it do that. After all, it was not designed to be a bench gun.
Ammo is a bit pricey but thankfully, Barack Obama's term in office taught me how to buy primers and ammo!!
