Learning peck drill

I need help. I have a 90° 1/4” spot drill, then 3mm (.118) pilot drill, followed by C (.242) drill finishing with a .2495 reamer. The reamer cleans up the ID but the .242 drill eats up the top and its bigger than .250 What am I doing wrong? Second picture is the program for the peck drill .242. I figured shallower cuts would be helpful but it’s not… I know it says D .246 but I changed bits. Material is copper
