Like I said before my cases have no signs of dangerous pressures. 3932+150=4082fps so an ESTIMATE of 4100fps is not that far off. All rifles are different and shoot different.

The MAX load is not the TRUE MAX load either. The reloading books are not going to be liable for someone using their suggested max load and blowing their gun up. There is a large SAFETEY FACTOR. The gun manufacturers also have a large safety factor in their firearms as well. They don't want to be responsible for someone blowing their gun up with standard handloads or factory loads. It will take a lot more pressure than what my loads are generating to blow my gun up.

A good example of this is Hornadys Light Magnum loads. The current 7x57 Mauser Light Magnum load is a 139gr SST over 2900fps. Look at your latest Hornady manual at the 7x57 Mauser. See what the max load for the 139gr bullet is using IMR 4350. It should be 45.9gr at 2600fps. Hornadys 1973 Second edition has the same 139gr bullet with 50.9gr of IMR 4350 at 2900fps.

Reloading manuals are guides, they should be used as guides.
