320grit lapping compound for FL die neck area

[DSbur]

Honing out a Redding .308 FL sizing die in the neck area, anyone local have a small supply of 320grit Clover (oil) lapping compound they can direct me to? Don't know what I'd do with a 1# can I'd have to buy otherwise...

Redding doesn't offer a service to hone dies in this regard.

If anyone has experience here please chime in. My current Redding Type S bushing dies work fine but I get a nasty donut at the shoulder/neck junction that I'd like to bump out with a modified FL die. (It's a .308-F/TR thing...)

Planning on using a modified AcroLap barrel lap.

Thanks in advance-

Maybe try a NAPA store. They have a couple of different compounds in small quantities for about $5.
