[QUOTE="RT2506, post: 877693, member: 10178"] As to how you load a 6.5X55 depends on what action your are shooting it in. If it is a modern action the load data that you find is low pressure and you can boost it up quite a bit. If it is a small action Mauser action like the Swede military rifles used then you need to stay with the data published for under 46000 CUP. IMR 4895 is a bit fast burning to get best velocity. The 6.5X55 likes the 4350s to H4831 powders for best velocity in any barrel length. For 129 gr Hornady bullets and IMR 4895 in under 46000 CUP loads 40 grs would be about max. In a modern action you can go up but you are on your own because there is no published data I have seen for the higher pressure loads. I would suggest that you get some IMR 4350 and work up toward 46 grs to stay under 46000 CUP but in a modern action you could work up to around 49 grs safely. I shoot the 6.5X55in the 96 Mauser rifles and for a hunting load I used Nosler 120 BT or Sierra sp with 46 grs AA4350. From the 29" barrel it does right at 3000 fps.
