Its a pistol powder that I buy from maine cartridge co.It burns a little faster then unique but slower then 231.The best part is the cost.30 pounds of the powder is min order but its only 10.00 a pound delivered to the door.My favorite loads are;
45 acp-185 gr swc-6.2 gr
9mm -115 gr jhp-4.2 gr
I allso have loads worked up for 38 sp.
If interested email ma and will give you there phone number.They do not take credit cards and shipping is a little slow but it allways gets to you.I have ordered a total of 90 lbs so far.Split with a number of other reloaders around here and everyone likes it.I have one guy loading 30 carbine with it.
