Review of Starlines new 270 Win Brass:

I purchased factory direct their bulk packed 250 count box, these will be used to form my 06 series JDJ cartridges. I?ve only fire-formed two trial cases which formed beautifully to 280 JDJ, case length of 2.490" and internal case capacity of 75.8 grains of water.

Very glad to see Starline continue to extend their brass offerings!

Arrives loose boxed in a large plastic bag.
Case necks do show some dents which is common with bulk packaged brass. Full length resizing would be recommended to square the case prior to loading.
Primer hole is very uniform and appears to be clear of burrs.

I weighted 25 randomly chosen cases from the box

Average case weight 189.8 grains
High weight 194.0 grains
Low weight 188.6 grains
Extreme spread of 5.4 grains
Case length 2.530"
Case neck thickness .015"

When compared to other brands:
