I have 284 win with 22" barrel and mag limit of 2.8". Never had any sort of trouble with feeding but I have had some trouble getting near max velocity loads that will also shoot accurately. The rifle is extremely light and mabye thats partially to blame and also the throat is very long so every bullet has a huge jump to the rifling. The best combo so far has been 140 ttsx, the closer to 3000 fps the tighter the groups get (sub moa), but I keep it around 2950 and deal with a little less accuracy. The heaviest bullet I've tried is the 154 sst but the ogive is so long (not sure if thats the right term), that the case mouth doesnt touch the bullet when seated at 2.8", I can run them over 2800 but accuracy for this rifle and that bullet is best at mid 2700's. I may try 160 accubonds if I can ever find any. With high BC bullets and most suitable powders, you will be dealing with compressed loads.
