I must warn you that you may not enjoy the tiny, narrow lube groves in the end.
In the past I tried to keep the mold design as close to the original as possible and ended up with poor lube retention and leading. Regret not using a modern bullet profile.

Kinetic pullers are easy to make out of ABS or PVC tubing. A length of each 1/2" and 3/4" tube would last a while and allow the pullers to be essentially disposable.
