But dollar for dollar the 5.7 seems like a totals waste of money.the power of the factory sport round is leaves some thing to be desired but it is far from a 22 mag. keep in mind the velocities you see for the 22 mag is for a 16" barrel not a pistol with a 5 inch. . .
Sure it packs more punch than a 22 Magnum, but it packs less than a 223/5.56. Its sort of that middle ground for which there is very little use. Not quite as good as the 5.56 and not so much better than the 22 Magnum to justify the cost.
