I'd build the whole belt then color it, then recondition it. Good old pure neatsfoot oil and/or skidmores are my go to for conditioning.

I discovered that if the case mouth is dented that he resizing and belling dies do not restore it to round and it will wrinkle when attempting to seat a bullet.

I have a short tapered mandrel made from an old punch that I use to remove any dents in the case mouth before resizing. Since I started doing that I haven't wrinkled another case.

Jusr checked Hodgdon's website and they do not list H4227 anywhere. They only lisr IMR4227.

I know at one time there was both an H4227 and an IMR4227. But to the best of my knowledge H4227 was discontinued several years ago. Lots of discussion about the similarities, differences, and possible formula changes but no concrete data from Hodgdon to back up those opinions.

I agree that if the grains are of different sizes and colors that the only fitting use for that bottle is as fertilizer. That said, you could call Hodgdon and ask them.

Yes I'm having fun, yes I am glad I talked them into doing it on the 18th instead of yesterday.  When the surgeon asked why I wanted to I showed him a picture of me with Cub Scouts and told him another group of kids was expecting me.  He said one of the best reasons he ever heard, and waiting is not dangerous just an extra 2 weeks to hurt, so used to it that it don't matter.

Well, it's set up to go for Saturday's Match. Got the magnets mounted to help keep the long guns in place. Using bungee cords as they are easy to mount and dismount. Using a pistol case at the bottom of the long gun seat to hold the guns in place and found out it holds a box of 12 Gauge shells perfectly.
