Comparison of Starline, Rem & Win Brass

[TexasMac]

Hey guys,

Here’s everything I know about Starline, Remington & Winchester .45-70 brass. Based on the photo and dimensions you can see why Winchester carries more capacity. Note the difference in wall thickness and the relatively sharp transition from the solid head to the walls. Also note that Rem. has slightly thicker walls than Starline. The main reason why Starline has less capacity than Browning is the design of how the head transitions to the web region. Since a Starline case weighs more than Rem. case but has slightly thinner walls, the weight difference is in the head.

BTW, I always deburr the primer hole in my Remington brass. Based on what I found when sectioning the cases, I’d definitely recommend deburring Win. cases. I checked several Win. new cases and the burrs in all were significantly worse than Remington or Starline. Notice the ridge sticking up in the primer hole in the Win. case. It extended 3/4 of the way around the hole. Based on what I found, Starline may not benefit from deburring.

Starline kinda looks like crap doesn't it. Suppose if one could make a reamer to smooth out the inside of a Starline case it would help?

Brian,

If the inside top of the head/base is viewed with a light, you'll see a flat ring surrounding the hole, than a step up to another larger diameter flat ring prior that transitions to the wall. Personally I would not be concerned about the small step in the base.

I spotted an error in the initial posting text. It should read "The main reason why Starline has less capacity than Remington is the design of how the head transitions to the web region." I had Browning on the brain because that's the rifle I normally use.
