Nice pattern - doesn't take long to get a LOT of patches cut. Some guys use office supply sheet paper shears. Faster yet with the larger models.

Found this picture in my camera - couldn't remember if I'd posted it or not as I remember I was going to.

This is my bullet patching block & patch pattern - .45 or .50 cal. I think.

The block-tray, works for any sized bullet. The 1/8" wide groove, with the patch under the bullet, allows you to get a good grip as you push down and roll the bullet up out of the groove. It makes patching much easier to get a nice tight fit of patch to bullet. Running black lines gives reference to align bullets the same each time.
The bottom of the block has a couple 1" wide stips of maple screwed or glued to it, for clamping in a vise or supporting on the table, off the surface. This also helps with rolling on the patches.

310gr. .375 for illustration purposes only. The bullets were given to me, I've no idea if they are commercial or not, but appear to be - all well cast and lubed with Rooster Red.
