Aloha Steve,
I'm on Maui but was raised in Kailua, and spent many a weekend while growing up at the Kokohead range with my Dad, or High School buddies. I have been shooting a Marlin 1894 .44 mag for almost 30 years a gift from Dad when I was 16, my Wild Boar rifle of choice all these years. That's a great round you chose for a conversion. May I ask who preformed the work? Was it someone local? Another great conversion I have heard, and seen pics of is a rebarrel of a Marlin 44 mag to 50EA (Dessert Eagle) the 50EA having the same rim, and OAL of the 44 mag so not that involved, and factory ammo available in a pinch. I figure a Marlin with 16" Trapper barrel in 50AE would make the ultimate Hawaiian pig gun. Slim pickin's as far as the gun market here in the islands but it helps to find a decent FFL dealer. Finally found one here on Maui, and giving him alot of business via Gunbroker.com.
A hui hou, Ji
