I'm just getting into casting for 30 cal rifle and was finding it hard to find any 30 cal moulds in the big box stores in Regina. One of their "experts" was quite surprised that one would cast bullets for rifles other than large black powder calibres. I know my cast .38 bullets work well in my 35 Remington. Anyway I found Leo at Boomer's Moulds in Regina and he custom built the mould I was looking for and also was selling a hand built locking mould handles that are nicer than the lee type that I have now. I learnt lots from Leo as well. I was impressed and am happy with the result.
