I'm putting together a wannabe .375 Lee Speed on a Long Lee action with an original worn-out .303 Enfield barrel re-bored to .375-.303. I'd like to get the rise between front and rear sight heights close to the original. Would someone be able to tell me the difference in height above bore (tip of front sight and bottom of 100yd V-notch) on the original rifle? Then I'll be able to calculate the height of front ramp to use with the express rear sight that I have. Thanks.
