RWS RELOADING DATA

KINDLY TAKE NOTE OF THE FOLLOWING DISCLAIMER OF LIABILITY WHEN USING THIS DATA!

Use of the loading data is exclusively at your own risk.

It is well known that the ballistic values of a cartridge – of which some will be relevant to safety – depend on the dimensions of the individual firearm, the quality of components used and the various environmental influences.

This information is provided entirely without liability, as we have no control over the circumstances of storage, processing, use, load, additional factors affecting use of the powder, careful selection of other components or the condition of the firearm itself. Moreover, each reloader must ensure, on their own responsibility, that the tools, equipment, other utensils and ammunition components (bullet, cartridge case, powder and primer) they use are in a flawless condition.

For these understandable reasons, we repeatedly and explicitly point out that no liability is assumed for use of this data.

Please take note furthermore that there has been amendment in the ammunition proofing legislation (BescvhG) that stipulates a switch in measuring method using crusher cylinders made of copper to piezoelectric pressure sensors (“quartz”). Due to the different measuring methods, the maximum admissible gas pressures that currently apply are not directly comparable with the values in the “Blue Reloading Book”.

We therefore recommend that you follow the recommendation that is consistently provided elsewhere and gradually approach the newly defined maximum admissible gas pressure by beginning with an initial load that is around 5% below the stated maximum charge (0.03 gram/approx. 0.5 grain increments for rifle cartridges; 0.005 gram/approx. 0.1 grain increments for handgun cartridges). Always be aware of any indications of excessive gas pressure. It may also be advisable to have the gas pressure of your individual load checked by a competent proofing offices or by DEVA, the German Experimental and Test Institute for Hunting and Sporting Firearms.

The currently valid maximum admissible gas pressures and dimensions are listed online in the CIP Tables of Dimensions and are available for public access.
