I doubt that I qualify as hard core, but I sure qualify as cheap. I also demand high levels of performance from me and my gear.
Rattle all that in a box and I cut at the muzzle when I'm playing at being a range rat, then "cut at the muzzle" to load my block for hunting. It's so darned easy, works so well and is so cheap I can't convince myself to stop.
Cutting at the muzzle (or loading block) will teach you new meanings for sharp knives. When yours is sharp enough, it will do it easily with a single pass. Even a little dull and you'll get frustrated sawing away at your patch material.
Paste- or grease-type lubes rather than liquids work best for me for hunts when loading from blocks. I have confirmed it at the range, cuzz I always shoot from the block to start each range session. Haven't found a liquid yet that does as well as paste or grease after the balls have sat in a block for a week or two.
Here's a useful tip: Adjust the thickness of your loading block to match the caliber. The blocks work best if you seat the balls so they stick out the bottom a little. That just makes it easier to find the bore with the ball when you're in a hurry. You want the block thick enough so that when the ball is sticking out like that, the top of the ball is just below the top of the block so you can cut the patch in the right spot once the ball is seated. Turns out that if the block is the same thickness as ball diamter, it's just right for deep seating the ball and cutting the patch as I describe. I adjust block thickness using my bench-mount disc sander.
