Well I've had trouble finding good brass for the .300 win mag the past few years. My last lot was once fired brass from federal fusions, which were surprisingly the best I've come across in a while.
I picked up some Sig Sauer brass in 300 win mag because I need new brass and figured I would give it a try.
Here are results of the 50 pieces
By weight
254.4 grain HIGH
249.5 LOW
252 AVERAGE
Selecting a 3 grain range from 250.5-253.5 nets me 44 pieces. 3 were lower 3 were higher
By length
2.613 HIGH
2.603 LOW
2.609 AVERAGE
43 fell between 2.608-2.611.
By neck wall thickness
0.0165 HIGH
.011 LOW
.013 AVERAGE
45 fell between .012-.016
If I used the 3 different ranges I would keep 40 to reload.
It looks like I would have to run about 20 out of the 50 thru the sizing die because the mouth is quite out of round. I resize them all anyways but for those who wouldn't, their is a very high percent of damaged case mouths.
