Hey guys, long time member, just don't post much. Question for y'all. Anyone here ever used Thunderbird T322 for loading .223? I just picked up (3) 8lb jugs of it on auction from a shooter that passed. I know this stuff is regarded as gold by 6PPC BR shooters, but powder in larger lots is still damn near impossible to come by in my neck of the woods and I need something to get my 3-gun ammo loaded for the 2015 season.
Now information on this stuff is kinda all over the board, from what I've been able to find. Some say the burn rate is close to H322 which would usually make it a little hot for heavy bullets in .223, but I've also found someone say it was like magic for their 77gr loads. I've also read that the burn rate is closer to TAC, which is generally known to work well for the heavier .223 bullets. Yes, I understand burn rate doesn't always correlate with how a particular powder/bullet is going to perform. Just looking for information from some of the fine, knowledgeable folks on this board.
So has anyone here actually used this mystical fairy dust to load 77gr bullets in .223? I know this is gonna make some folks cringe, but if it doesn't work well, I'm most likely going to end up using it to load 55gr FMJ's for hoser stages that don't have shots beyond 2-300 yards and some 50gr V-max loads for varmint hunting. Looks like it should be excellent for light bullets.
Any input is appreciated, Thanks
