ALTOONA, Iowa (AP) -

Vendors at an Iowa gun show are reporting a boost in sales in the wake of the shooting that killed 20 students and six staff members at a Connecticut elementary school.

The Des Moines Register reports that the sales appear to have increased because of fears that politicians will enact new gun restrictions following the Dec. 14 massacre at Sandy Hook Elementary School.

Gary Boswell, owner of the Lamoni-based Boswell Guns and Ammo, says his sales at the Des Moines Gun & Knife Show have been brisk. Boswell says he sold out of .223-caliber cartridges for semi-automatic rifles, the same ammunition that was used in the school shooting. He also sold all but one of the .223 rifles that he brought to the show.
