510 Whisper

[600NE]

Looking for suggestions for a bullet mold for my 510 Whisper -- Something 650-750g.

Accurate Molds and if the stock designs don’t move you you can design your own. MP molds has a great 525 grain solid and it drops at 500 grains when the large hollow point pin is used b

Depending on what you hope to accomplish, I don't see much advantage going over 500-600 grains.

I had a NOE 513-888 mold at one time, but sold it to someone on here. I usually shoot 450-600 grain cast boolits. After shooting those, I just didn't see what an extra 200-325 grains would get me excep emptying the pot faster.

What is your twist rate? Mine is a 1-14 twist better suited to the lighter boolits, although the 513-888 was supposed to be stable as well.

If you want to try some boolits, I have the 513-580 spitzer gas check and plain based as well as two MP 640 designs, a 450 GC HP and the 525 plain base HP.

I Have a couple of NOE 650 Round nose, and a 525 HP... They drop nice and very consistent boolits. Been Shooting 645 Gr Pulls. They work well too.
