Re: 38 loads
Yes, just use the lead bullet loads for the same weight plated bullets.
I was not kidding about the pick. I had to use a pick to get the lumps of lead out of my barrel every time I used cast bullets. This was after a bunch of time using a lead removal cloth too, and a lead removal tool.
Sizing the bullets to match the barrel sounds good but buying plated bullets is easier although not less expensive. I go for easy. I don't cast my own either... been there done that... but not again. It s too dangerous and way too much work for too little savings.
