I would suggest the 17HMR. And for anyone who has never had one! They will amaze you and at 2500 Ft. Per Second. In addition if you get a Savage, Marlin Varmint model or other good quality rifle you can expect 1/2" groups at 100 yards off a rest.
I have many High Power Rifles and enjoy shooting it as well as any. And as stated, a box of 50 runs around $12.00 at Wally World.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
-- John F. Kennedy
