To answer your question; Yes, & to reduce muzzle blast, & recoil. & I don't have a thing against saving powder. An over-charge is an over-charge, no matter the burn rate of the powder. One can overcharge 4350 as easy as Red Dot. That is why I weigh & process every round one at a time no matter the powder used. I don't trust powder throwers for one reason, I use a Lot of bulky powders. Like 800x, SR-4759, & stick powders. -06
