We buy Cheddite for 117/5000, the Win and Fed are up around 125 to 140. I've been reloading low pressure shells for around 15 years and at 7500psi and under and don't feel there's a problem with subbing in Win, Cheddite, Rem, or CCI's. I've also used many a jug of Promo because it's so much cheaper. Is there a little powder left in the barrel ? Yea, but it goes out the next shot. With a break open gun there's no problem. JMHO
