I'm down to 2 boxes of 12 ga 2 1/2" RST low pressure shells.
I've been successfully shooting Federal Top Gun 12 ga 2 3/4", 1145 fps, 2 3/4 dram eq., 1 1/8 oz shells out of my French 2 1/2" chambered SxS. It has impressive barrel wall thickness. I'd like to try them in my Damascus barreled Reilly hammer gun. How can one find out the pressures generated by this round? Previous discussions indicated the Federal shells had the lowest pressure in general. Will writing to Federal help?
(I know we've been down this route before but it's time to fish or cut bait on the Reilly hammer gun. RST is still hors de combat. Either put it on the shelf, get back into reloading - it you can find the components, shoot the French gun with its 3/4 chokes, or just give up and shoot the 20 and 16 gauge).
My Federal shells are quite old, bought during the height of the pandemic shortage but they match this Federal load currently advertised except mine ar 7 1/2 not 8:
