[QUOTE="Shortmagman, post: 194271, member: 10723"] Gary, Iron Workers advise is good. I also own a 270 WSM with a long throat. I can not get the listed velocity using the loading manuals as a guide. I was using IMR-4350 and getting only 3050ft/sec with Nosler 140 Accubonds at the max load listed in Nosler Manual #5. I switched to RL-22 and slowly moved up the powder charge. I am now getting 3150 ft/sec but I am over the max listed for RL-22 using a 140 grain bullet. However, I have no pressure signs and I can reload my brass many times without neck splits or stretched primer pockets, so I am not worried about the pressure. According to Nosler Manual #6 you should be able to get 3200 ft/sec out of a 24 inch barreled 270 WSM using three different powders (Magnum, Viht N170,Magpro) I don't know if you can get either powder. I am very pleased with RL-22 for both accuracy and velocity. You might try it if you can get it in New Zealand. Good luck. [/QUOTE]
