    It's prolly a typo.

    In any case, the 4.7gr load is safe unless its 7.4 ;)

    I personally would pull them.
    My load for .38 Special with Trail Boss is 4.2 gr.
    That is with a case trimmed at 1.145.
    A Lee T.L. cast 158 gr. SWC with a length of .655

    A COL of 1.450

    That leaves a seating depth of .350
    with an available case space of .360

    I then measured out 4.7 grains of Trail Boss in a primed case and came out with an available case space of .340

    By those measurements it leaves a compressed load by .010.

    Folks that have actually used TB were well aware that a load 15% over max as listed in a published manual was close to or above being compressed. Not an assumption, but fact. We also know it does not like to be compressed. This is why there was concern and the question of % asked. Again since TrailBoss is loaded to volume, no assumptions of caliber needed to be made. Since making assumptions and then responding to a question about reloading is irresponsible and foolish, I took exception to being included in your blanket statement. If you made an error and assumed something, I give you credit for admitting it. But don't ASSUME the rest of us made the same error.

    Just a little off-topic, but illustrative.

    I am surprised at the amount of difference, but not so surprised that there are increases. Magnum primer instead of standard and 10" barrel instead of 7.7".

    It really does drive home the point of re-working up loads whenever you change any component.

    I don't often comment about overloading rounds, but MY standard 38 special 158 lead SWC with Trailboss is 4.6 grns. I shoot them all the time with no issues. It does not exceed the full case requirement "for me".

    It is an overload so you take your chances.

    My recommendation is pull them if you have not worked up your loads to this level.

    Lee lists a max load of 9 grains of TB for 30-30. I load 10.5 grains with no issues. As long as it isn't compressed you should be OK, IMHO.

    I'll be the umpteenth person to say they are probably fine, but go ahead and shoot them in a 357 just to really cover your butt. As mentioned above, I've also overloaded Trail Boss in 30-30 to no ill effect.

    The only risk I see, based on the knowledgeable comments all ready posted, is for them to be on the high side pressure wise, getting lost in the mix, and end up in a weaker gun.

    I've been cleaning up the man cave, and finding all sorts of "odds & ends". Like a handful of 9mm, no 2 or 3 the same. Some are reloads, some commercial, so tossed them into a bag for disposal during the next trip to the range. Now I know none of them are overloaded, but some may be slightly underloaded, and won't cycle the slide. I recognize one of those, potentially, but I don't know about the rest. My point is, they have a nasty habit of finding their way out of the place they belong into somewhere else. So if you decide to shoot them, at least mark and segregate them.

    I would put them in my beefiest .357 wheel gun and let fly. But I am not real smart. With certain powders my rule is dip the case in the powder, shake it off level and seat bullet of choice. No guns pieces removed from body by surgeon yet.

    Same load that I use, and no signs of pressure.

    As the OP didn't state what firearm he was using these in (38Spl, 38Spl+P, 357Mag), and without being able to physically see&measure the case, bullet, seating depth, etc. to determine whether the TrailBoss is compressed or not I would personally add my vote to the "Pull Em" list. If there is additional information forthcoming, that might cause me to change my vote. But technically speaking, the "recipe" wasn't followed, and even though TB can be safe in a case as long as it isn't compressed, I can't be sure that it isn't compressed given what info was provided.

    Just my $.02 and probably worth less than that.

    P.S I use TrailBoss in my 45 Colt and 45/70 mouse-plinking loads (even the 45/70 load is subsonic) and they aren't full in those cases

    Oh, we think you can be trusted to beat yourself up for it.

    Here's what I would do.

    Check other manuals and see if the 4.1 is particularly conservative. This might give some peace of mind. Re-check the cartridge dimensions. Cartridge length is a proxy for the important measurement, the volume UNDER the bullet.

    Load a few rounds with 4.0 some with 4.1, some with 4.2, some with 4.3, 4.4 and so forth.

    Shoot the 4.0 and inspect for signs of overpressure (sticky extraction, flattened primers, stuff like that). Then the 4.1 and so forth. Stop if you get overpressure.

    With Trail Boss, as has been posted before, there is little chance of overpressure, but the general procedure outlined above should work for any such "accidents", even with other powders.

    Caution is the watchword.

    I just loaded with TB for the first time, really enjoyable to work with.

    So many people worried about which caliber and which handgun, why? Hodgdon sells us you can not cause an overpressure situation with Trail Boss. You CAN NOT get enough Trail Boss into a case as long as you don't compress the load to cause any pressure problems, period!

    But, this is only true for Trail Boss and not other smokeless powders.

    Yep. I came in to say the same thing, but Lost Sheep beat me to it, with Savanahsdad seconding. We all know how to work up a load; with fifteen minutes additional work you can find your answer and probably learn a little in the process.

    I'd be very surprised if you see any pressure signs with a full uncompressed load of TB in .38 special. The recommended max loads for 148WC felt like squibs.
