[QUOTE="Shortmagman, post: 1106378, member: 10723"] What is the length of your barrel? If it is 24 inches 3200 is a good number. however, you may in some cases be able to reach 3300 ft/sec.. The Hodgdon web site shows 67.0 grains of H4831 reaches just over 3200, but with your accuracy you may not want to try more powder. I have shot and loaded 270 WSM's for a number of years and I have yet to find a good load that would give 3300 ft/sec.. The very hot factory Winchester 130 Silver BT's gave me around 3240 f/sec out of two different barrels. I am now using IMR-7977 with Berger 150 VLD's and getting over 3100 ft/sec but even the data given with this powder does not show getting over 3300 with a 130 grain bullet. The Alliant web sit shows that you can get over 3300 with RL-26 out of a 24 inch barrel, but I have yet to try RL-26. [/QUOTE]
