Thread: 284 win vs 280ai

I have a 280ai on a M52 Cooper 3 lug action. It feeds perfectly and there is no catching on the case when drawing the bolt. The sako may have a different lug position though. The benefits of seating bullets longer are overstated generally and If i was in your position I wold throat the chamber so the loaded round would fit the magazine. Im still shooting whats left of my 162 Amax supply. Seated with a .040 jump at 3.380 OAL and running 2950 from a from a 23 inch barrel. The only time you will see any real gain in seating long is if it gives you enough room to drop a burn rate but modern powders like RL 23 largely negate that.
@Puffin your comparison on the other thread is flawed in that by using 2209 you have picked a burn rate the suits the 284 but is faster than ideal for the 280ai putting it at a disadvantage. . I would also add that of all the combinations Iv run through QL over the years the 280ai consistently showed the the largest discrepancies.
