I'm anxiously awaiting a new custom rifle that should be completed soon and I'd like some load information. My gun will have the ARC Nucleus action and a Proof Carbon Sendero 26" barrel chambered in 28 Nosler with a 1:8 twist, throated for ELD-M 180gn. bullets. I'll also load Sledge Hammer 143gn bullets that are supposed to be insensitive to seating depth. I will be using N570 powder.... (I got lucky and actually found some N570!) Can any of you with similar barrels tell me where your accuracy nodes are and what bullets they are for? I'm looking for high nodes as well as lower nodes.
