Being a novice with casting I have a question. I will be casting my first batch of bullets soon. I have two friends with size lubers that will help me with the lubing the new bullets.

So this is the question, one size luber is a Lyman and the other is an RCBS. I need to buy the die for my bullet size. Are these dies interchangeable just like the dies used in the reloading presses?

Thanks
