I am taking my JC Higgins - model 583.18 in 16 Gauge Bolt-Action out on Monday for the New Jersey Spring Opener. Shoots really good!! Barrel is marked -Full and weighes about 6 Pounds. I found some OLD 16 Gauge copper plated ammo. American Eagle brand. Over 20 years old. They shoot great. I painted this shotgun green and had to fabricate a trigger guard for it. Probably just load one shell. It does not look like much-- but powders those clay pigeons!
