I load 225gr Speer and Nosler bullets in front of 69.5 gr IMR-4831. That has been my load for over 30 years, with my Rugers. I load 67gr for my TCR, same bullets same powder.
Never heard of Deep Curl bullets
OK I looked them up. New bullets made by Speer. I'd check the Speer manual, but believe the load I use would still be the same if I switched bullets.
