24" 8" twist Brux 130g Nosler accubond, Barnes 127g Long range 41.0g of win 760 cci 250 Hornady brass, fired many times shoots less than 3/8" groups 3130 fps
3180 is a safe max working load; groups opens just a smidge
Velocity seems very high to me, for that bullet/charge weight. Nosler data shows 2900 fps as a realistic expectation, fwiw.
