Forgot to mention the gun I use is ingersoll's 2135timax10yr with what they advertise as 1100 ft/lbs. Pretty sure it's actually around 780 ft/lbs. Very strong gun though, that's what broke the hf sockets.
Shallow sockets wouldn't help me at all being I have swivel sockets, the gun is to large to fit in small spaces anyway, so an extension and swivel socket get in that same place.
are those impact swivel and extensions or regular ones?
