RE: Duds , misfires ,WTH.
Afellow at the range handed me 4 boxes 1 lot Federal Power Shock 150gr soft points brand new to go with his brand new 06' . Even the last of my WWII brass only tipped in about 189+- for the heavies . I use a Lyman Ohaus "M5" scale with a calibration weight and check true 0 every time I start a job and beforeI scale powder . I use the calibration weight maybe 3 or 4 times a year . The point in weighing the cases was to cull the odd cases that were beyond the 1gr over/under of the scale as my rifle is obscenely touchy see "range work ??".
I just tell it like I see it on the gear .
The powder clump was the question just wanted to give enough info .
I burned off the charge today took a second match in my burn bowl to get it to go wondering if it was a bad primer I've used about 10,000 cci's and never had a miss fire .
