I have nothing at all against good lead bullets, but I think that lead bullets may not work as well in a Micro-groove barrel as do jacketed ones, leaving aside the question of leading. Plinking loads are one thing, but good, stout but not stupid hunting loads are another. Gas checks make the difference, I know, but I am hoping to find a good jacketd bullet load that will work well in both the handgun and the rifle without undue stress on either and still get the job done well. That may not be possible, and I realize that compromises result in something that is not the best anywhere, even if it is acceptable most everywhere.
I really was not favoring the 180 grain to begin with, since I tend to like heavier bullets. I would rather err on the side of no expansion and plenty of penetration than to risk a bullet "blowing up" on the surface and not getting inside to do its job. I also realize that a white tail is a different animal than a tough old hawg, so one bullet might not be appropriate. Perhaps two bullets, same weight so they shoot to the same point of aim, but one designed to be tougher than the other??
Ron, I really appreciate what you had to say. I understand the warning about reducing H-110 and W-296 loads. I have some experience with .357 mag in similar handguns and a Marlin Lever rifle. So what I am really searching for here is some guidance to good loads in the 240 grain plus bullet weights that work well for you in your Micro grooved barrel, and which will still be acceptable in my S&W Model 29. Is that asking too much? Thanks again for your help ...
