[QUOTE="brianwinzor, post: 591700, member: 1067"] I do not own a 7mm RUM so I cannot give you data for that cartridge. However, I have used Viht N170 in a 25/06AI, 257Weatherby, and 300 RUM. I have found that my lot of Viht N170 is virtually identical in burning rate in the above cartrideges to AR2225 (H Retumbo in USA) In my Rem 700 300 RUM (similar case capacity to 7mm RUM) using Remington Cases, and Federal 215 primer: 180 grain Nosler BT 100.0 grains AR 2225 - 3289 (Max) 100.0 grains Viht N170- 3292 (Max) 100.0 grains Viht N570 - 3313 Max) I suggest that when using Vihtavouri N170 you start about 10 % below your Hodgdon Retumbo maximum loads that you used previously in your 7mm RUM and work up from there. Hope that the above is of some help. Regards, Brian [/QUOTE]
