Just as a point of reference regarding prices of 5.7X28 vs .22RF.
Midway lists the 5.7 at $203 for 500. Their .22rf prices are $20-$33 for a brick of your basic .22s.
Use....when we say that "they" are using the 5.7 for hunting....ya gotta remember that "they" do lots of things that range into the iffy.
Just because you can, doesn't mean you should.
