shot-shell question

[J.B. Books]

Low recoil does not always equate to low pressure. A minimum dram 7/8 ounce (26 gram) load will be gentle on the wood and the shoulder. Published pressures on factory ammo are hard to find. Often times ammo makers use small amounts (= less $) of fast burning powder. This holds costs down but brings pressures up. If chamber pressure is a concern it is best to shoot one's own reloads. In the 80's before I knew much of anything I ran all kinds of stuff through 1913 Trojan 12ga. Lots of 1 1/4 factory loads and reloads and some early 1 3/8 ounce 2 3/4" Bismuth factory loads. The gun remains tight as drum. Most fluid steel 2 frame 12's will take whatever you feed them without trouble.
