I bought a box of cast bullets from my local gun store. They are 230 gr round nose. I've set my powder measure to 4.8 gr of Winchester 231. The OAL of the cartridge is 1.269". The bullets have a horizontal line at the base of the head of the bullet about 1/8" above the wax ring. The line is approximately 1/16" above the casing. Is that a problem? Hope that makes sense.
