What I did when my father passed away was take some of his ashes and make sure all his kids, grandkids and hunting friends got some. Here's how I did that:
I took some of the empty brass from his 7mm Mag and cleaned them up in a case tumbler after I neck sized them. I put a small wad of cotton into the cases and them put his ashes in and sealed them with a bullet. I then put a small eye screw into the primer hole so they can be hung up and I engraved his initials in the brass.
I gave them to the people and everyone of them hung them on the rear view mirrors of their cars and trucks. So, now Pop still gets to go hunting and fishing with his family and friends every time they go. I find a lot of comfort knowing he is still in the woods with me.
