Tim - I'm not so sure I'm going to hold my breath for those flex-tips to hit the reloader's market. I've been using wide flat-nosed cast slugs in my levers for the past couple of years and the old style lever action loads before that and really prefer the way the flatter nosed stuff takes game, especially the wide flat nosed slugs. I still recommend those slugs to those fellas who use single shot handguns in the field
I realize you can get a few more feet/sec out of the newer slugs and they have a flatter trajectory but I just don't feel they hit quite as hard as the flat nosed stuff does. And we both know that ballistic gelatin isn't an adequate measure of bone busting capability on game animals.
I also think the 225 gn slug in a 44 is a tad light. I prefer heavier slugs (have I said that before???).
Guns and Ammo recently ran an article on using heavy broad flat nose big metplat cast slugs in an African hunt and the results are telling (telling me to stick with the heavy cast wide flat nosed slugs, that is.....).
So that's just my two cents worth. Mikey.
