Palmetto State Armory has some very attractive AR pistol kits in the .300 Blackout cartridge. I believe they are 1 in 8 twist barrels.And I have an unused Aero lower receiver. Casting for 5.56 doesn't right now interest me, but the 30 caliber is quite attractive. And I read that the cartridge can use 110 to 220 grain slugs, for great versatility.
I'm sure it's been done and I've read several threads about it, but now that the cartridge is becoming mainstream and there are a number of different powders new to the market, I'm wondering what folks here think of casting for this new darling of the sport? Cast slugs in a gas operated platform is completely foreign to me. Lube clog gas ports? Gas checks give troubles near the gas port?
I prefer to stay close to subsonic. Not because I have a suppressor, but because that's my favorite way of shooting.
Thoughts on the latest findings and experiences sure appreciated.
Thanks as always. Don.
