Jeff Head, one of the organizers of the 50 Million Round March, is rallying pro-gun fathers and their families to "march" to shooting ranges around the country on Father's Day and fire-off 50 million rounds of ammunition "as a statement in support of the right to keep and bear arms for all law abiding citizens."

However, says Head, what is best is to allow law-abiding Americans the right to choose their own method of self-defense and family protection -- including the "uninfringed" benefit of the Constitution's 2nd Amendment right to keep and bear arms.

"Historically it is clear that it would be 'best for the children' for the people to remain armed. Responsible firearm ownership and use are one of the great hallmarks for American liberty and our unprecedented peace and prosperity as a people," Head noted.

Organizers said the event, which officially started Tuesday, had already garnered the support of many websites, gun shops, firing ranges and media outlets.

"Honest Americans will continue to be at a disadvantage to armed criminals until the current 20,000 gun laws are repealed," said Libertarian presidential candidate Harry Browne. "None of these laws stops violent crime; all of them intrude into our privacy and our ability to defend ourselves. Thus, I wish the 50 Million Round March well."

"They're going to try to fire-off 50 million rounds of ammunition at training ranges across America on Sunday and I'll bet they do it," said Alan Korwin, author of several books on gun law and publisher of Bloomfield Press. "The mainstream media has been silent about it but men everywhere seem to be looking forward to it. It's simple and elegant -- a wholesome family outing in support of the Bill of Rights."

The National Rifle Association, in its weekend online NRA Live, provided a detailed report of the Father's Day event, including an interview with Head.

"I think gun owners are waking up and realizing that they can't compromise anymore," said Ginny Simone, host of NRA Live's weekend report, commenting on the event.

"At this point in American history, the 50 Million Round March is the right idea at the right time," added Aaron Zelman, executive director of the Jews for the Preservation of Firearms Ownership. "This effort is a very sound but simple idea to send a direct message to all of those who despise liberty. May any such individuals hear the volleys at the firing ranges and quake in their jackboots."

The event is also supported by the Second Amendment Sisters, a pro-firearms women's group that held a counter-march to the Million Mom March in Washington last month.

"We are pleased to support the idea of fathers and their children coming together to enjoy a family holiday by participating in a shared interest and what, for many, is an honored tradition that has been passed through the generations," said the Second Amendment Sisters in a statement released this week.

During the event, shooters from around the country "will safely discharge over 50 million rounds from personal firearms in the space of two hours without harm or injury to those taking part at any official shooting range around the country," said Head. "This in itself will send a powerful message regarding firearm safety and responsible use by law-abiding citizens."

Range monitors will be present at ranges to ensure firearm safety, he added.

Group organizers said follow-up events -- which Head would like to see annually -- are being planned for Independence Day, Thanksgiving Day, New Year's Day and Presidents' Day, along with a yearly Father's Day event. No mention was made of Mother's Day.

In addition to target shooting, each event would include a letter-writing campaign directed at congressional representatives and senators, as well as state governors and the U.S. president, informing them of the shooter's participation in the event and their "insistence that infringements on this constitutional right cease."

"As a memento of the event, the participants will include either one of their used targets with their letters or two spent cartridges in a mailer box with their letters," said a statement.

Officials said they did not want shooters to send in silhouette targets -- targets with outlines in the shape of a person -- or live ammunition, only spent cartridges and simple paper targets with "bull's-eye-type" centers or images. Organizers also ask that participants do not send threatening letters or images such as actual photographs of lawmakers or officials with bullet holes in them. Organizers have already designed a sample target participants can download and use.

Head emphasized that the focus of the event is simply to let officials and lawmakers know that a healthy number of Americans care about and appreciate gun rights, and to remind lawmakers that gun ownership and use is a "right constitutionally guaranteed."
