    from the Sierra website:


    It has come to our attention that some of the printed loads for the Remington 300 Ultra Mag in our 5th Edition Rifle and Handgun Reloading Manual and Infinity Suite Computer Software exceed the SAAMI maximum pressure suggestions. Use of these loads may result in damage to firearms and or bodily injury.

    For purchasers of the 5th Edition Rifle and Handgun Reloading Manual, please contact Sierra directly at 888-223-3006 or by email at sierra@sierrabullets.com. Please look at the data pages for the 300 RUM (page 617). If there is an "r" after the page number in the right corner, you have the revised data. If not, let us know and we'll send you a replacement section of data immediately. Please remove and discard the pages 617-622 currently in your manual.

    For purchasers of the Infinity Suite Computer Software, a program patch is available on our website, www.sierrabullets.com . Please click the Download Patch link to receive the program patch. For those of you who do not have internet access, please contact Sierra Bullets.

    If you need any additional information concerning this notice, please call 800-223-8799 or send an e-mail to Sierra@Sierrabullets.com.

    Thank you for your cooperation in this matter.

    Just as a matter of interest, how long have Siera known about this problem?
    I bought my No 5 manual mid 2004 and i have the revised data.

    This safety notice has been out for quite awhile. Not sure of the original posting date.
