Hello. I've got a question about obtaining .45 super brass. I heard from somewhere that you could trim .308 win brass down to .45 super dimensions for your brass. Is this true?

Easier to trim .45 WinMag shells. You can make them out of .308 brass but need to inside neck ream the cases as the walls end up too thick to chamber ordinary sized bullets.

I believe Starline has 45 super brass.

The question of trimming down 308 or 30-06 brass down to 45acp comes up all t the time.

I have tried it.
It is lots of work to get it to work right, and not at all worth the trouble.
The wall thickness at the mouth is too thick and needs reaming.

45acp almost every brand, Starline 45 Super, and Starline 460 Rowland brass are all of the same strength and thickness.

Starline 45acp +P is thicker walled, heavier, and has less case capacity.

The man at Starline may contradict me with his heat treat speal.
Joe at realguns may contradict me with what his cross sections look like to him.
But I know what happened in all those work ups back in 2001 in my 1903 Turk converted to 45acp and shot with CCI 200 large rifle primers.
And I know what I saw when I weighed the brass and cross sectioned it.

If I want to shoot heavy loads in a 45acp, the real problems are recoil and case support.
To shoot 45 Super loads in a poor case support pistol with a light slide, I did a couple tricks:
1) 152 gr SWC bullet makes less recoil
2) Power Pistol powder makes less pressure to get high velocity
3) Starline +P brass bridges the gap better across the poor case support with the thicker wall.
4) With a 3.16" barrel I am getting 1226 fps ~ 1257 fps

The semi wad cutter punches a big hole through paper and a big hole through animals.

I am carrying 152 gr, 12 gr Power Pistol, Lee heavy factory crimp, Starline +P brass, WLP, 1.275", resized after loaded to make sure they drop in the chamber.
This I can shoot in a Para Ord officer size pistol. Their larger pistols have great support, but the Hawg is a real turkey for case support, in the trouble to get it to feed. The 1.275" is a must to get it to feed.

In the rifle with rifle primers, I can go to ~50 psi until the primers fall out with any old 45acp brass, just as good as 45 Super brass, no difference.

He's not the only one. The cross sectioned cases look pretty clear to me.

So, what you're saying Clark is that the Starline .45 ACP +P brass is actually thicker and would be better suited for pushing the round faster than the Starline .45 Super brass? That's interesting. Looks like I've got more reading to do.

Here's a link to the 1st of a very informative 3 part article from Real Guns.

Links to the 2nd and 3rd parts are at the bottom of the 1st part.
The cross sectioned brass is in part 1.

Good Luck...

The man at Starline got part of it right when he said that +P is for guns with poor case support and that 45 Super and 460 Rowland are for guns with good case support.

Joe D'Alessandro's articles on 45 Super had a big influence on me in 2000, and by May 2000 I worked up past 460 Rowland loads with mixed 45acp brass in a 20 ounce pistol.

I am taking this data now, but the brass was probably made a few years ago:
New unfired unprimed +P 91.6 gr
New unfired unprimed 45 Super 90.7 gr
