For years South Florida has been plagued with invasive Iguanas. Most counties Miami-Dade and Monroe do not allow a discharge of a rifle or pistol unless you own over 5 or more acres. Air rifles and pistols are not firearms unless you live in the Peoples Republic of New Jersey, NY, or Massachusetts. You can't own a sling shot in New Jersey! Of course the Felons all own guns and the DA's don't prosecute them. Anyhow most south Florida residents in urban areas take out the Iguanas with pellet rifles and pistols. Its taken awhile to get a rifle that really works. The Sheridan 5mm pneumatic pump rifle works very well. I have turned a few friends on to this rifle shooting a solid lead skirted pellet. However the big lunkers require a little more lead to take them out. Bought a Beeman 25 cal pre charged pneumatic (PCP). This rifle was made in England by Theobean Rapide and is of excellent quality. This rifle needed a little tuning but it drives a 31 grain lead pellet 900 fps and shoots raggety hole groups @ 50 FT. You have to charge the air cylinder to 200 BAR (3000 psi) with a scuba bottle or I bought a little lunch box size compressor that pumps up the tank in 3 minutes.The Beeman has a 12 shot rotary magazine too. It's fun to shoot in the yard and the Iguana's are getting thinned out.Attachment 323532 One year I shot 56 of the critters. My friend is a lobsterman. We stuff the Iguanas in the lobster traps and send them to the bottom and exchange them for lobsters. Good trade!
