Anybody here shooting a .45 Super in a 1911?

[Ithaca Gunner]

I've been looking at calibers other than .45ACP for a future build, and the .45 Super has caught my attention. It's a bit less than the .460 Rowland, but more than a .45ACP+P. Wondering if anyone here has one and could give opinion of it in a 1911.

If you want to build one, crank up your google fu , I would start with the required stuff for a full pressure ten mm.
Ramped barrel , flat bottom firing pin retainer, heaver springs, maybe a buffer, metal plates under the grips [ or Pachmyers] if you blow a case.
I have an officers 10mm being built and every thing is important.

I have throated a couple of KKM and Lone Wolf barrels for the Glock guys who run .45 Super seated out long in .45 ACP brass and it works out well from what they tell me, shoots lights out too! This one has .300" of .4525" freebore and will plunk anything that will cycle through the mag.

You would be well advised to seek out a good 400 series stainless barrel that is good for 70,000psi not that you will run that much but a standard barrel cannot take the .45 Super pressures without risking a KB. Karl Lippard sells a 416R heat treated barrel that's good to 78kpsi for a little under $200 which is along the lines of what you would need for this build. I like his barrel links too, takes a LOT of the slop out of the bicycle chain type original 1911 toggle link.

I run 45 super, but not in an auto. Guess I could in my 1911, but it works fine in ACP, and I only have so much brass. I use it in my blackhawk with a conversion cyl. It is a step up from ACP, not as much as the Rowland. Im not really restricted in bullets w mine. I had a bunch of the 225 gr flex tips so have been using them in the super. I looked at stuff like the 400corbon, but the super is so easy, no dies or anything to buy.

Thanks Groo& Doug Guy, mine will be a 416R stainless Combat Commander with all the features you stated with the exception of the ramped barrel, the barrel is an Ed Brown 416 stainless barrel. I may do the Karl Lippard link, it looks like a simple mill job on the frame and effective. A Fire Dragon dual action recoil spring system, flat bottom firing spring stop, extra power springs, Pachmyer Signature steel insert grips, and Star-Line .45 Super brass. My loads will probably be more on the .45 ACP+P side than Super, a 200gr. JHP at around 1050-1100fps.

Never thought of using the Super in a revolver, but looks like a great idea in a Ruger convertible.

Please re think ramped barrel unless you shoot 45 super brass only!!!!!!!!!!!!!!!!!!!!!!
The weak link of the auto system is the cut away section where the ramp is.
Where a revolver uses the brass as a seal [ there is steel all the way around] in an auto
the brass is part of the chamber [ where the ramp is] and must support the pressure.
Also be sure you use Pachmyer grips with load development as splinters are not fun.

Was shooting some of my supers this weekend. I have the midlength barrel on my ruger, so not much different than a 1911. Mine are not max loads, use power pistol. The 200gr XTP avg of 1156fps, those 225gr FTX were running 1101 avg. They wont quite fall out of the cylinder, just need a fingernail. Friend of mine likes the 45 super now that he knows what it is, is planning a 1911 build. Its not much behind ruger level 45 colt. The same XTP with a warm ruger load of unique in the same gun were 1174 avg fps. That conversion cyl is nice, its hard to buy 45 colt cheap, but it eats any kind of 45 acp you can find.

I meant to put it in my previous post. I have 500 new Star-Line .45 Super brass on the way. Later this month 1911builders.com should be offering several 416R stainless frames cut for ramped barrels, (I've been begging for these for some time now) and I want to be one of the first to get one. The Super will be more a +P gun than an actual Super. Frame, slide, and barrel are all 416 stainless with a Fire Dragon recoil system, (22lb. spring around a full length duel action guide rod that buffers itself during the final stage of recoil). I've been thinking about a compensator also, but probably won't need it, the plan is to carefully work up to around 1,100fps with a 200gr. hollow point.

IG,

Been doing this quite a while on 1911's. I have had complete success with Clark comp'd 45 acp barrels, one fitted Ed Brown barrel, and one fitted Kart barrel . All of this on a full size 1911 (also in a S&W 625). All three barrels exhibit about the same amount of ramp throating (unsupported case) and all will easily do 230's to 1100 fps in Starline 45 Super brass, and Longshot powder. 200's should not be a problem. The 230's at 1100 fps seems to be about the top end of where the recoil and gun functioning get harsh, without running a comp. You might find this "ceiling" a little sooner, in a Commander.

I would only caveat that the full support would be good if you have a situation of extreme bullet setback when feeding, however you set up the gun. A safety margin, if you will.

Thank you. Glad you did an Ed Brown. I like their barrels.
