The 6.5X55 Swedes are throated so you can load the looooooog 160 gr RN bullets. I have 4 of the Swede military Mauser rifles , one sported with a scope that I hunt with some, and they all have the long throat. I have found that loading 120 to 140 gr bullets to an OAL of 3.050 which is as long as will work through my magazines well works great. One other thing that I have used in other rifles that have long throats that has greatly imporved the accuracy is to use a Lee Factory Crimp Die on the loads. This die makes it's own crimp groove so you can use it on any bullet. The principle behind it is to hold the bullet for that mill-a-second in the case just like the bullet hitting the lands will do in rounds loaded just off the lands so the pressure builds up good before the bullet leaves the case. I don't know if this is the reason or not but I do know that when I use this type crimp on long throat cambered rifles it shoots more accurate than loads not crimped. The only caliber that I could not tell the difference in is my Swedes. They both shot the same which is pretty good.
46 grs Accurate Arms 4350 with a 120 Nosler ballistic tip or 45 grs Accurate Arms 4350 with a Sierra or Hornady 140 gr bullet really shoots and scoots in my Swedes.
