I recently picked up an Ideal Long Range with ejectors and 3" chambers, mfg 1925 with London steel barrels. Patterned using 2.5" loads 1 1/8 oz and 3 drams BP I got 91% and 94% at 30yds with a 30' circle. Its in very good condition, shows good case colors, minimal wear and no cracks in the stock. Since it has 3" chambers and is the Long Range I expect it could take a higher psi load than a normal 2.5 or 2 5/8 chambered gun of the same vintage. Trying to decide on an appropriate 3" load for it. What would be the maximum 'safe' psi I should be cautious of?
