Two Littleton men have filed a proposed ballot measure that seeks to undo proposed legislation that would limit ammunition magazines of more than 15 rounds.

The measure was filed Tuesday, one day after the Democratic-controlled Senate passed a bill limiting magazine rounds.

Tim LeVier and J.T. Davis want voters to decide the issue in the 2014 election. Neither could be reached for comment.

House Bill 1224 is a part of a far-reaching package of Democratic gun control legislation that Republicans and Second Amendment activists have denounced as unworkable and unconstitutional.

The proposed ballot measure would amend the state’ constitution so that only Colorado voters can decide whether to limit or restrict ammunition storage and devices.

The proposal was submitted to the nonpartisan Legislative Council, the first in a number of steps in getting an issue on the ballot.

House Bill 1224 — which is sponsored by Rep. Rhonda Fields, D-Aurora — is going back to the House, so lawmakers there can consider amendments to the bill made in the Senate.

It originally passed through the House in February and Gov. John Hickenlooper has indicated he will sign the bill into law if it arrives at his desk.

If HB 1224 becomes law, anyone who currently possesses a magazine that holds more than 15 rounds is able to keep it, though if they transfer or sell the magazine, that individual would face a class 2 misdemeanor charge.

“People can do a ballot measure” Fields said. “That’s something they have a right to do.”

On Monday, a pair of Republican Senators said they would not abide by law.

“I will willfully and purposefully and civilly disobey this law,” said Sen. Greg Brophy, R-Wray.
