Also happy customer here...And what comes on HP pin system on MP molds... On my mind it is far better than few other customer makers system. I find NOE's molds also excellent quality and good to cast but that RG pin system isn't that good. Thats just my opinion. Those brackets are more prone to move or bent etc. vs that cramer system.
Accurate is also good and you can always send mold to Eric @ hollowpointmolds to make it HP mold. If I recall right Eric uses same system on HP like MP does. If you don't need any HP boolits or under 7 mm molds Accurate is place to get quality molds also. Have a pile of all makers molds...NOE, Accurate and MP if you don't count commercials molds like RCBS etc.
