I can find all the 17 HMR ammo I want to buy for $13.99 for a 50 round box, but at the same time I see little or no 22 magnum ammo. I only went to 2 stores in my town, but they both had a surplus of 17 HMR, but no 22 magnum ammo. I usually buy 22 magnum ammo when I find it. Is this true in other places too? Both cartridges fill just about the same niche, so it might pay to have a rifle in each caliber if a speedy rimfire is what you need.
