280ai reloading help

[slapshot88]

Hello all,
I have a Weatherby backcountry 2.0 with a 1-9 twist 24" barrel. I have 145 Barnes lrx and 160 nosler accubonds. I have N555 powder. Looking to build up a load using nosler brass for this coming season. Any help would be appreciated.
Cheers brothers.

I havent tried N555, but I have worked up a decent load with N560 and 160 accubonds. I started load development for my 280AI about 2 years ago using Nosler brass, but ultimately transitioned to Peterson brass. I just find it is much more consistent.

My preference is RL23, although it is difficult to find most of the time.

Im not at the house right now but I'll share my recipe that works well in that gun. I cant remember if its 7828ssc or 4831ssc. Buddy brought it into town and we made a load for it. It took Nosler and Peterson brass well. 150 and 175gr Accubonds. When I get back into town Ill snap a pic of the recipe board.

Not a lot of help but I’m using H4831 with Berger 175’s.

I haven't tried n555 in mine but it seems a bit fast for me. What does the vihtavuori app say? I would start at max 280 rem data for that bullet weight and carefully work up from there.
