Interesting thread. I have a box of Remington brass from years back, new brass never loaded. Headstamp RP 7MM.
To answer the OP's question, I've been doing a bit of work in the 7x57 with RL17 getting good velocity and very good accuracy in a Winchester M70 Featherweight. Been getting over 2800 FPS with the 150 gr. Nosler partition. but will be working with the 160 gr. Speer Hot Core spitzer and 170 gr. Sierra round nose shortly. Powder will be RL17.
