Best Powders for 12" 300-221

[jarhead1086]

That is a size I didn't know they made, I've only seen the larger ones like my brother has. My QSM is less than half the weight of my Thundertrap and smaller, but sounds as good super and only marginally louder shooting sub due to the volume like you say. It is still very quiet, but I am convinced that Hollywood quiet sub cans need volume to lower the volume : ) Since your small Jet is made as more of a moderator they may have gave the baffles extra clearance too and you could be getting some blow by. Blow by gas is supersonic and noisy. Try adding a squirt of Break Free CLP. You have a hard to get set up and it will be nice when its all together.

Mike Brown is actually a big supporter of the 300/221 and builds a lot of them on the 700 action. I'd like to get one of these for my daughter but the price is slowing me down, considering what I've spent on other things in the past few months. At one point he was talking about manufacturing ammo but I don't know what has happened with this. He chambered my Mike Rock AR barrels (12" & 7.5") with a short turnaround time. At one time I considered investing in his company but he didn't get a proposal to me in a timely manner so I increased my investment in LWRCi instead.

At one time LWRCi was going to make the 300/221 a standard offering but since the 6.8SPC has taken off it has been dropped. I doubt if any more will be built, other than my 7.5" upper.
