Anyone have any idea how often powders are tested and new data provided. It seems like a lot of manuals just recycle old data, add a minimum of new information and move on. Based on the fact that they were discussing data changing in lyman 45th edition how is every load of current cartridges up to date in psi in every manual currently published. There is also a ton of data held by companies were not getting access to. Ramshot is great providing data when called. I got a load for silhouette for 357 which is very helpful when I cant exactly run out and grab something else. I really like alliant but they have almost zero data for lead rifle bullets or reduced loads. Reloader 7 seems well supported and when off the reservation 4189 is close enough for some quality extrapolation. Alliant 10x is not very well represented and it's got me struggling.
