primers make a difference!

[odoylerules]

Thank you for making this post! I have read 100 times to try different primers but was just too pig headed to do so-stupid. My 300 WinMag has always done just fine with federal 215 primers. Fed 215's are supposed to be the shizit so why try others...After reading this I decided, what the hell I'll try It. I shot 20 rounds each with fed 210s and 215's. With the 210's my SD's went from 12.5 to 5.6! And my groups shrank some!!!
Thanks again guys!
