[QUOTE="4bycamper, post: 375105, member: 17128"] F210's are pretty hot so I don't know if WLRM's or F 215's will help unless in very cold weather. Even my WSM"s with their short fat powder column get a mag primer when hunting in Colorado snow country. My 7mm RM also likes WLRM primers all season long. I picture that long narrow powder column needing more heat to ignite well. Your first target shows a round group. I have no suggestions how to improve it. The second target shows 2 shots close together wit one further away. This suggests (to me ) to try a shorter bullet seating, for more bullet jump, say from .004 to .006 to .008" off the lands. Don't know why but this plan has been working for me for years. Good Shooting [/QUOTE]
