I'm not one of those guys with dozens of moulds. But I am one of those guys who believes it's worth it to buy a mould that the bullets drop out at pretty much exactly the dimensions I want, with minimal sizing required afterwards.
I have some RCBS 35 caliber rifle moulds that are very, very good, despite the fact they don't throw bullets of exactly the dimensions I would specifify if ordering a mould.
One of Veral Smith's moulds from back about 1993. Also very, very good.
Also an NOE and a SAECO... also pretty good.
I haven't tried them all but I turned to Accurate Moulds after... what's his name now... Rob Applegate?... became famous and turned to churning out his designs as fast as he could for the Cowboy crowd. No more custom work.
Anyways, I have purchased three Accurate Moulds, all brass, each of the two cavities being a different design. So, six different bullet designs, altered to conform to my measurement specifications. Every one of those mould cavities drops it's bullets with dimensions exactly as specified.
And he has dozens of different mould designs that you can use as the basis if you want to alter them.
I don't know if Accurate Moulds is the best, but their ability to put exactly what I specified in my hands is good enough for me if I ever want to add to my mould collection.
If I remember correctly, my last two cavity/two different designs mould cost $160 USD.
