Published in 2006, Terry Wielands book "Dangerous-Game Rifles"...actually mentions the 444, and has about a page worth of info on the cartridge, and, the Marlin lever gun. I was looking at the table of contents, and saw a chapter on lever guns....first asking myself why lever guns would be included in a book about (what I thought) was African dangerous game rifles, and when I turned to the chapter, I fly by the first few paragraphs about the Winchesters, and come across a statement by the author..."There is only one lever gun that can be considered a real dangerous game rifle. The Marlin 336", etc..............I was amazed! The author then goes on to talk of the 444 Marlin..........Nothing much there that most of us dont know about, but, he does state that the 444 with the Barnes 300 grain bullet is a "serious proposition"...even for the big bears! For a Marlin lever gun or the 444 to be mentioned in a book about dangerous game hunting just goes to show that the author sure had his facts straight! The author lives about 20 minutes from me...someday, I need to corner him and see if he has any more insight on lever guns and dangerous game. Would probably make for an interesting conversation!
