Robert,
I really don't think that any of the 200 grainers are gonna expand any at all, especially at the velocities that Mikey mentioned, and especially at velocities that can be reasonably generated out of a two inch barrel. You mention a major consideration of any 200 grain bullet. The additional length can cause problems of too much overall cartridge length for some revolver cylinders, especially if the round is crimped in the regular crimp groove.
That is why I asked the question. Bullet construction is definitely a consideration. Someone makes a 168 grain Keith style bullet that really looks good, and they claim it is designed so that the crimp groove seats it deeply enough in the case to keep overall length short enough to fit any cylinder. And it has a big flat face on it, that should really smack when it hits!
I am hoping that Mikey can shed a bit more light on just what bullet he is loading, and at what OAL, and maybe even with what load! Your full metal jacketed bullet will obviously not expand at all. The shape of it will determine how much shock it would transmit to its intended target. A round nose lead will slip right on through and may not disturb its target much initially even though it may be responsible for the demise of said target after a bit of time. Yours may also do the same.
I think I have seen a picture of your bullet. If so, it is a round nose with a small flat spot at the tip. I really think that the larger the flat spot, the better, especially for self defense purposes. I tend to prefer flat point jacketed bullets over hollow points for the same reason. I know this flys in the face of what many consider to be good advice for self defense rounds. But unless you drive a hollow point to screaming velocity, it will probably not expand out of a short barreled revolver, with the exception of a bullet designed to expand at lower velocity. Then you may have penetration issues. And a hollow point that fills up with leather, denim, polyester fiberfill or what ever has been demonstrated to act much like any other round nosed slug.
It is kind of a hard thing to make choices about. Everything is a compromise of some sort. What ever happens, in a self defense situation, if I have to fire at someone, I want to make certain that I get good hits and good penetration to hopefully hit the spinal column or other major bone/nerve structure, which will have the maximum possible effect to cause that person to immediately cease and desist. That is the intended result, to make 'em stop doing what ever it is they are doing that puts my life or someone else's life in jeopardy. And I also intend to keep on shootin' till they do stop or I run out of things to shoot. If death results, so be it.
I also know that overpentration can be an issue, but I will take my chances with that as opposed to little or no penetration. I don't think the bullets we are discussing would rate very high if evaluated by most of the "experts" who write about such things today. There are those who say we should not even consider using a handloaded round for self protection. That might be so, but anything can happen anywhere and things change pretty quickly in this day and time.
If the flag flys for me, I just want to be around to argue after the issue's over. I sincerely hope I am never again in that position. The liability is huge. But I really believe that it is just as important to be able to say that this round is the only round I use, and it is the only round I practice with, and I have practiced this much, firing approximately this many rounds, and I am supremely confident that I know where my rounds are going when I pull the trigger. I did not start this fight, so I am not really responsible for the results (as long as I have not done something that is patently irresponsible or stupid). That may very well not be agreed upon by whatever court I am standing before, but that's my story and I'm sticking to it!!
We each have to decide for ourselves what we are gonna do and what we are gonna do it with, and realize that we will have to accept the consequences of those choices, good or bad. The time to prepare is before the fact. Being ready is a state of mind as much as it is anything else. That is why I like to read and hear as much as I can about these things. Anybody's experience and opinion is worth considering, and sometimes the best thing we can learn is what NOT to do!!
