Labowner - in the past few years several of the powder manufacturers have changed some of their long-published loads. They say new and improved testing equipment has generated better data for them. Off the top of my head, the load changes that I have noticed have been in the direction of less powder. Close to home, last summer I found that my decades-old 20 ga. skeet load is now way off the charts. Unless I am mistaking, there are no current loads for 700X that get as low as 5000#, and the 7/8 oz loads (24 grams) are high velocity jobs. Check IMR's website and make certain your load specs are current.
