I had a long throated Argentinian 7x57 with long 29" bl., that with the old Norma 205, I got just over 2,700fps with 175gr. bullets.
I used it & that load with 175gr. Hornady SP's for a 3-position match (Vancouver Croatian style) of bench, sitting and standing. Using the battle sights, I placed second to a guy using a scoped .222 Sako. LOL - they didn't invite me to shoot with them again. That was 1976 - I could see and shoot then.
