    My 25-5 had .457" throats. I used 265 gr Keith's from Beartooth they sized to .456" and they shot very well. I only shot 1000 fps loads in it. I have since replaced the cylinder with one with "proper" throats cut to .4525" which is what all of my other 45 Colt's have been cut to so I can standardize on bullet diameter. My old cylinder.:D

    Obama said something along those lines during his "You didn't build that speech." There maybe unicorns out there, but my experience with oversized throats leads me to believe that they induce leading. Needless to say, but I do not believe your claim.

    It is interesting that S&W and Colt tightened up their throats in response to customer pressure when, according to you, it does not matter. Can you explain the mechanics of leading? Have you read anything about it?

    Maybe we are talking about two different things. I'm talking about the complete absence of leading after a few hundred rounds. Are you talking about a tolerable amount of leading after 20 rounds? What is tolerable?

    If you want this to remain civil, leave the Obama comments out of it.

    I never said it did not matter. I said that oversized throats are not a guarantee that it will lead with standard .452's. Which is absolutely true, whether you choose to believe it or not. Who do you think is buying all those commercial .452" bullets, people too stupid to know what leading is???

    I don't know about S&W but Colt never tightened up theirs. Even brand new & improved SAA's have oversized throats. USFA and Freedom Arms are the only sixgun manufacturers that have consistent throats appropriate for .452's. Ruger is all over the board.

    Thanks to all who have joined in this discussion!

    OK,... I did some double checking and my initial info was correct.
    Cylinder mouths are .457 ( checked with die makers pin gages ) Bore slugged at .452.

    Regarding the suggestions about replacing the cylinder,
    This is a 30+ year old 6" Mod. 25 in a presentation case, 99% condition with sentimantal value. So, for these reasons I wouldn't want to risk sending it to S & W for a new cylinder for fear the blueing wouldn't match the original, not mention the cost involved.
    It is a casual shooter, not a serious target gun so I'm ok working with it the way it is.

    The main focus of my original question I asked is;
    What would be the best cast lead bullet to load given the .457 cylinder & .452 bore sizes.
    It doesn't sound like going +.002 in bullet Dia. / bore will be a problem.
    Loading fairly warm loads is fine by me, especially if it will help seal the bullet base to minimize leading.
    Is there any real difference between RNFP & Keith style SWC's in performance?

    I like Unique for .45LC, but its always good to hear what others have found worked for them.

    Thanks to all for the lively discission & input on this subject.

    Like has been mentioned, stick with the 12'ish BHN range and you will be fine, no need for harder. I am shooting less than that, and to the 12-1300fps range loads with some plain based loads in my 41, 44, and 454, and not loading up my barrels with streaks of lead.

    As for the design, either will/should work well, just more of a personal preference than anything. If your planning on reaching out to 75 or 100yds you might go with the Keith SWC designs, of staying under that and possibly hunting with it the RFN's are great.(might have the RFN SWC range thing backwards, I do that sometimes)

    If your possibly looking to start casting your own, the Lee .452-255, is a great one to start with. It shoots VERY well from my Ruger 45 Colt with standard or Ruger only loads. It also is quite a load in my 454 as well. Even if your NOT looking to cast yourself that particular design is a GREAT one for most 45 Colt loads.

    Do yourself one small favor, ok maybe two, pick up a package of the copper Chore Boy pads, (make sure they are copper and not copper plated steel) and also possibly pick up one bottle of Lee Alox. "IF" you find the bullets DO lead, you can pull one strand off the Chore Boy pad and wrap it around a 45 cal bore brush and it will help cut the lead out quickly.

    Again, "IF" you find that your bullets DO lead, don't give up on them just yet. Give them a coat of the Alox first, and give it another go, just coat right over the factory lube. IF you feel up to doing a little mixing, you can use the 45/45/10 lube made up from the Alox and some Johnsons Paste Wax, which dries to a non sticky finish. Also with the Alox, a little bit goes a LONG way so don't use but a small bit, about a thumb nail sized glob will easily do 50-100 bullets. Folks say if you can see the difference in color on the bullets you used too much, I usually use too much. Just figure that to a point a little more doesn't hurt, smoke more yes, but doesn't hurt.

    The Alox is only around $8 a bottle, which to me is not much to give somethig a try especially if it helps out, and your not scrubbing lead, plus one bottle will lube who knows how many bullets. I use the 45/45/10 version on everything from my 38SPl's to my full tilt gc'ed 454 and have no issues with leading what so ever. Lucky, maybe, but I don't figure luck would carry through across all of those loads and calibers without the lube doing it's job.

    If your interested in the 45/45/10, you can find the info on it here,
    Tumble Lubing--Made Easy & Mess-Free

    There is also a LOT of info on the 45 Colt on that site as well.

    As for powders, Unique is a good one, it will be a bit sooty at the lower end loads. The Accurate powders #5,7,& 9 work well with this round, as does HS-6, W-230, and a few others. Some mention that Universal can be used almost as a direct cross over for loads using Unique and burns much cleaner. I haven't used it yet, and if I DID I would work up accordingly. I have however burned plenty of Unique and the Accurate powders and HS-6 all with great results. With my Ruger even shooting the standard Colt loads I haven't found anything to date that I would call unacceptable, but some loads have shot a bit better than others.

    You might also play with a couple of different primers, as some like the Winchester might be a bit much for some loads, where as the CCI, Federal, or even the Wolf LP, are perfect. Sometimes the Winchester, even though it is a great primer, has a bit more to it than is really needed with some powders.

    Hope this helps.
