STARLINE .45 Super brass is OOS right now with no backorders but has always been available in the past....and will be again.
Have read some posters over on the 1911 Forums who have set up their guns for .45 Super and used standard .45 ACP brass for +P+ loads, which is a step down from full Super loads, with zero issues when used with a ramped barrel and retarding the slide opening...

Paul...I agree...that is a little over the top for a 275...30k psi is all I would want to go...one doesn't need anything above 250 in a .45 ACP...

Ordered everything today to build a 45 Super out of a Fusion long slide. I’m pretty sure the Super will be sufficient for my plans which is deer/hogs to 75 yards. If down the road I think more power is necessary I can always up it to a 460 Rowland. What barrel did you get? I have a Springfield V16 in .45 super but I think the MANY popple holes drain too much energy from the 6" barrel. I recently got another 6" SS barrel for it and I'm going to eventually chrono both with some stout ACP loads to see if I wasted my time. The problem with the super is getting .45 super brass. Back in the day I made .45 Win mag brass from .308 (a PITA cutting and reaming them) but since .45 Win mag brass is available nowadays, it's probably a bet that cutting down Win mag brass is an easier possibility? Anyway, If my unported barrel turns out to give me a decent velocity boost, I may go the win mag brass route myself. Since this is just a 45 Super conversion and not up to 460 Rowland, I’m using the factory barrel. |

For your described use of the gun I can't imagine the .45 Super not taking care of business. Of course you know I run in in a Glock. It is a real killer on deer and I would use it for bear defense.

Just my personal experience but when limited to the COAL determined by a magazine feed pistol- the length of you brass isn’t near as critical as to having the said pistol properly set-up for increased pressures , slide velocity , etc. , etc. Won’t indulge into exact specifics of load cuz it’s never been lab tested for actual chamber pressure etc., but a 250ish grain RFN @ a very consistent 1120fps from a 5” m1911 style pistol a handles many, many real-life game hunting challenges with authority.
Will say the load has proven to be safe in a couple of m1911s as well as 2 m25/m625 revolvers with thousands of rounds thru each with zero issues. Stole the basic powder charge from a gun writer that used the powder charge
In S&W revolvers with real Lyman Keith 255 & auto-rim brass. Changed bullet profile for feeding relability, preferring the lee version of flat nose rounded ogive style nominal 250-255 slugs

As I said earlier I have a Springfield V16 .45 super which has many popple holes in its bull barrel and a proportionally ported slide. With some ACP loads the muzzle flash is very bright (disconcerting to others nearby not me) and the gun innards get really filthy which is bothersome. Recently I started to think about getting an unported .45 ACP barrel for it to eventually chronograph the differences between the ported and unported barrels. Since I have no plans on actually shooting .45 Super in it I'm not interested in the published velocity of super loads, for that I have a 10mm. Good thing too because Springfield's super barrel was claimed to be better supported than an ACP barrel.
Luckily in their wisdom, foresight or whatever they called it, Springfield made the bushing cuts in the slide! Egads! Even in the late 1990's and early 2000's when this one was made, a manufacturer making unnecessary tool changes and spending additional build time with no immediate benefit was a huge surprise. So, I found a new drop in 6" non-ramped unported "NM" barrel online at around half the price of an unfitted bull barrel, and I have to get it out and stretch its legs this weekend.
More to come.

I've been playing with and loading 45 super since about 2005. I started with a 6" springfield without the ported barrel and factory BBA 185g 45 super ammo would run just over 1400fps and 230s would be in the 1180fps range. Duplicating those numbers was pretty easy with power pistol. I later added a threaded barrel and compensator setup and tested various 45acp brass strength to see in 45 super specific brass was "needed". Running winchester, remington, federal, blazer and a few others 45acp brass i could get up to full rowland level loads without any case bulge in the unramped barrel. I then setup a factory ruger sr1911 for 45 super with a flat bottom fps, buffer and heavier main and recoil spring and again worked up to full house 460 rowland data in the factory ruger barrel. These loads were 1500fps in the ruger with 185s and 1600fps in the comped longslide. So brass strength is not an issue at least in 1911s, I have had some bulge in a factory g21 barrel with super loads in acp brass so I swapped to a threaded aftermarket barrel and haven't had issues since.
The posts above are correct, the key with the super and rowland level loads is setting the pistol up for such. In your case where you would be in the +p-+p+ loads (which is plenty for most scenarios) i would get a flat bottom fps and a little bit heavier recoil spring and call it a day. I also throat my barrels to run swc and wider meplat bullets seated out to what the mag will take and doing that really makes the 45 super setup very versatile.
