FYI 25mm Puteaux Anti-Tank gun, original and reloads too much recoil

I shot my anti tank Puteaux and I am getting full recoil with both original and reloads.
Reloads:
projos are brass at 296 grams=.65 lbs=10.44 oz
Reloaded Powder is 4oz cannon grade=113 grams
Originals:
Original projos are 322 grams=.71lbs=11.36 oz
Original powder is unknown

Full recoil so I will try 3 oz and 2.5 oz next time(see screen shot from Video)

Any suggestions or comments from experienced gunners are welcome and appreciated.

I hope you keep the Recoil Cylinder full of Hydraulic Jack Fluid ! I had both the 1934 and the 1937 light Gun and I fired about 25 Full size Rds and a lot of reloads with Pyrodex And I never had my Barrel recoil that far ! I had a Browning 50 Cal Barrel turned down to fit for cheaper Shooting ! They are Great little AT Guns ! I have a Service Armament Catalog from 1963 and the AT Guns were $125.00 and Ammo was $2.50 each ! Those were the days ! Don Shaffer N.E. Ohio

You want to fill your recoil cylinder with mineral oil if it is low but really it is just for counter recoil and that dose not matter much. 4oz ss is a little hot. 3.5 is where you should be. Original loads always max out your recoil stroke.
