I suppose I really don't have a specific question folks. Mostly hoping for other's thoughts to ponder right now. Thanks to folks here and lots of time reading threads, tutorials and researching, I've become a so-so caster and real enthusiast about the art. I recently assembled an AR pistol in 5.56 from a Palmetto State Armory kit and am quite happy with the results. Accurate and just plain fun, I have another lower receiver waiting for surplus cash to appear (grin) to fund another kit. I had decided the next would be .300 Blackout because of the ease of casting for the round and powder coating the slugs for use in the gas operated gun. I'm a range shooter. I cannot hunt any more. I'm not a competitor either, shooting hundreds of rounds weekly. I also am on a fixed income and jacketed slugs are pricey.
Conversely, I've aged though and wish to limit calibers somewhat.
Am I missing an opportunity to enjoy casting for the 5.56 cartridge, experimenting with loads, and learning powder coating and gas checking? The .30 caliber round has more options of course. But is the 5.56 a good candidate too but I'm missing the signs? DO folks think maybe I'm setting myself up for frustration and likely failure wondering if I should just choose another 5.56 kit and learn to cast for this cartridge?
Thank you all for taking a moment to offer thoughts. Don.
