NOE is your best bet. Accurate molds is my go-to mold maker but they don't make 25 caliber molds.
The Lymans are hit and miss at best, the quality control is not what it was and they regularly are cut undersize and drop bullets that are too skinny. RCBS makes some good stuff still, but availability and price means you can get a 4 cavity NOE for about the same price as a single or double cavity Lyman or RCBS mold.
If you order a GC mold from NOE be sure to order gas checks at the same time and save extra shipping charges.
