Any others out there using the 280 Ackley??
One advantage I found with the longer barrel like in my 280AI loading powder like IMR-7828ssc using Nosler data start load is 57.5gr @ 2856fps and max is 61.5gr @ 3043fps. I load 58.5gr/IMR-7828ssc @3038fps with 160gr AB and 56gr/R-17 same bullet @ 3046fps. I had my 280AI throated little longer and if I went to max loads using IMR-7828ssc I'd be well over 3100fps same with R-17.
Don't get me wrong I'm pushing powder I using and I'm sure anyone putting 28"long barrel would understand advantage to doing that. I started couple grs under start loads.
