I have the Max, 454, 444, 45-70, 500 S&W, and 30-30 all covered. There is a lot of overlap between them as far as range and useability are concerned. I have used them all on various game critters and other reactive targets. The 444 is the most versatile one of the lot, with the 45-70 and 30-30 in a close race for second. Paco Kelly had a lot to say about the 444 in his writings, and my findings follow along with his. His reload data is a bit brisk for my liking, but he is the lever gun/lever gun caliber guru. The 444 is a heavy hitter with good distance capability, but any heavy chunk of lead is going to have somewhat of an artillery trajectory, no matter what the launch caliber is. All these calibers are useful, all have their rabid fans, it's just up to you to decide what recoil level, component cost, and cool factor, (or lack thereof) you are willing to accomodate. I know if I could only have one of those, it would be the 444.
