The specified angle for the angle at the front of the cocking piece is 4 deg. I understand that (perhaps) Envoy/Enforcer and perhaps L39, the angle was varied, to say 7 degrees.

I have two No4 cocking pieces adjusted to 7 deg and intend to try them out.

Anyone got any info on this area?

Predictions on the effect on the let-off weight would be appreciated.
