I made several out of cut offs I had from oak stair treads. Forstner bit & drill press. I also made me a box for my shell holders same way. I have some plexi glass 1.5” thick was going to use it but I don’t know if it would ruin my bit. I had been to cheap to by Forstner bits and got a set dirt cheap because wooden box with plastic front was busted. Porter Cable brand. Always made do with paddle bits before.
Drilled 17 rows of 3 across in a 2x4 =51 holes using pc of scrap for a splinter guard at the bottom.
Then I turned the 2x4 on edge and sawed it in half.
I glued a pc of plywood 1/4 inch on bottom of each board.
I sanded the two boards and varnished them fifty years ago.
The holes were drilled with a 1/2 inch spade bit for .45 cases.
Since then, I have used them for everything from .45 down to .25 since the holes are so shallow.
Best thing i ever did.
As for double charges.
After I get the powder measure zeroed for my charge, I carefully throw all the charges and I check them all with a penlight.
Usually I purposely throw a double in the last one to see what a double looks like.
Then I dump the double and throw a single in that one.
A double is easy to spot when you know what the difference looks like.
Normally I hold the measure in my left hand and lever out using the right.
I carry the measure to the cases.
Works for me!
I also throw a double charge on the last one sometimes to see it for the check. I don't mention that often because it could cause someone else a catastrophic mistake. I don't work between loading blocks. The only time I use one is when I spray lube rifle cases and when I charge cases. For charging I go from a Tupperware bowl to the measure to the block. Then check them with a light.
I occasionally load without a block too. Especially if I'm using a dipper. I'll charge about ten cases, lining them up on the bench. Then I check the powder and seat bullets.
