So I have an update on this. The local took/die shop I talked to for modifying the type S die quoted $50-100. The guy mentioned earlier in this thread that does alot of these mods (JLC precision) quoted me less and it was really affordable. I think the price was also the same for having my FL die modded to a bushing style die that could use Redding bushings.
Talking to the Redding CS guy, he said they could hone the neck in my die to a larger diameter (0.335 specified by me), even though they don't typically do that. So, I decided to return the 6.5-284 die I bought. If I need/want to, I'll just send this FL die to JLC Precision. I received my die back today, and it looks like they just made a new one for me. When I sent it, I didn't include the recapping stem and expanding but because I don't use it. They included one with the new die they sent... So that's cool. On the return sheet it says they replaced the die due to the probkems I had with it but it didn't say anything about honing the neck.
So, I'll size a couple tonight and we'll see!
I think it was overall a 2.5ish week turnaround.
Thanks Jay at Redding!
