Major Power Factor vs Target Velocity??

[UT PROSIM]

i was looking at Missouri bullet co's 45 acp bullets and i saw that they have two different types of 200gr SWC bullets, Major Power Factor and target velocity.

I am shooting 200gr SWC's right now and need more, whats the difference in the two?
thanks

The Major Power Factor bullets are harder alloy - Brinnell 18 - than the target load bullets - Brinnell 12 - meant to be shot at lower velocity.
Or that is what it says on their website.

what are the pros and cons of harder alloy? they both cost the same.

Most USPSA/IDPA pistol matches mandate shooters to meet Power Factor required for their shooting classification since light recoil loads will give unfair advantage.

To meet these power factors, bullets must be driven to mid to high load data range. Harder lead bullets (BHN 18) can better withstand the high velocities without leading the barrel.

The softer target (BHN 12) lead bullets will obturate (base of the bullet flattens from primer igniting powder charge/gas expanding and seals bullet base to rifling) well even with start to mid load data range, providing accuracy and less leading.

It depends on how you reload your bullets. If you stay in the low/mid range and get some leading, you may want to consider softer 12 BHN bullets. If you stay in the mid/high range and do not get leading, you may want to consider 18 BHN bullets.
