I'm looking to get a list together of shorter bullets 150 grain to load 2.800 COAL 284 win. I'm not interested in loading 140's, in my mind if I was gonna shoot 140's I could have got a 0.277 or 6.5 gun. I tested some #1913 sierra gamekings and the accuracy was erratic vertically with 0.5 powder increases. The nosler partition was what I was hoping to load but the bullet is 1.220". This is on the max of bullet lengths I want to use. At this length they start to intrude on powder space. The 145gr Speer HotCor might be the closest to what I'm looking for......even though it's a touch light. The Speer grand slam 150s I think discontinued may be good too. I wanted to try the flat base bullet next to see if the gun likes them better. Idk the twist rate but I'm guessing it will like them better. The Winchester PowerPoint 150 shoots good, if I if it's sensitive to charge increase/decrease because this is factory ammo I'm referencing. That's supposed to be a flat based bullet. I see I can buy the win PowerPoint components to reload, that may be my best option. On a quest to get the gun to shoot to same point of aim as factory win PowerPoint........buy the same bullet for my reloads!
