I am sending off several different loads for pressure testing. I am interested in a source for pressures that were safe for vintage American doubles. I am aware a that they may not be relevant because of the age/condition of the gun but this seems a good place to start. I know some of the info that has been put out on the internet is likely dangerous, some just very adventurous. I am not trying to develop maximum pressure loads but instead loads that will be effective on mixed bag waterfowl. The performance of loads not in the ITX manual have so far worked best, pressure testing is the next step. Any info would be much appreciated.
