.45 Super

[yondering]

Triggerhappy, a flat bottomed firing pin stop is a good idea if you're going to work up some hot loads (you sound pretty familiar with 1911's and may know this already.) This is a common addition for full-house 10mm loads in 1911's. EGW makes them, not sure who else.

I have one in my Para P16-40, it's nice in that it delays lock time a little, and lets you get away with a lighter recoil spring (I don't like really heavy springs since they are hard on the gun too). My P16 handles full house 10mm level loads fine, but still runs with real light .40 S&W stuff. You should be able to get the same results in a .45, with something that will handle Super loads but also work with standard 45 ACP. I have not installed one in my .45 though.

I've been messing with the 45 Super for more than 12 years. If you need anything, let me know. I will say that favor a longslide for 45 Super use. I have also never had a problem with load segregation.

We were making 45-06 brass back in the 60s. Everyone thought we needed more power than a standard ACP would give. Live and learn. Most folks know better now. If I need more power I will carry my 44 mag. It that wont handle it I do have a few rifles.

Dean Grennell strikes again - I remember that period and finding steel cases from ww2 to coat with something (teflon?) putting in double springs and making 255 keith SWC loads at like 1100 fps we guestimated - someone actually cracked a frame with the stuff we were playing with.

only1asterisk, load data would be nice. Not much around. Hodgdon has some, but its limited to 20K CUP which isn't much more than standard and less than +p pressure

[mtgrs737]

45 super brass from Starline also has a different heat treat and the thicker webb section.

[Ridgerunner665]

+P brass, 230 grain Hornady XTP, and a large dose of Alliant Power Pistol.

Not in a 1911...but in a fully supported chamber (XD), I liked the 230 grain bullets at 1,050 fps. Thats not quite 45 Super...more like 45acp +P+.

I did play around with much hotter loads...but that one was powerful enough, and scary accurate.

I'm sorry but I'm not gonna post the load data...but if you have a Hornady manual, the load is not much over the MAX load listed there.

Would an EAA witness with a buffer and heavy mainspring stand up to .45 super? Rowland- (a comp is available)?

[Grapeshot]

Wasn't there a .451 Detonics Magnum floating around in the late 1970's? I understand that had a case that mirrored the .45ACP, or was it a few thousandths longer? In any case what I read about it was that any gun chambered for the .451 DM could shoot .45 ACP as well.

Then we have the .45 Winchester Magnum and the Wildey (SP) pistols.

[only1asterisk]

Couple to get you started:

These are to be considered MAX! Developed in a ramped barrel, use in your barrels at your own risk . Reduce 1.2 grains and start from there.

BD45 (239grns, Water dropped, WW)12 grains AA#7
SAECO #058 (222grns, Water Dropped, WW) 9.5 grains Longshot

AA#7, Longshot and Power Pistol are the best powders I've found. I 'll post some links and more data after a while.

[MtGun44]

My understanding is that Power Pistol is THE powder in .45 Super.

Also - for your application get some Hornady 230 FMJ FPs. Drill DEEP.

Having competed with the 1911 in IPSC for over 30 yrs, I know what you mean
about the skill set, but when I backpack in Wyoming near Yellowstone (Griz, blk
bear, wolves and DEFINITELY moose, plus 2 legged predators) I carry a S&W 329
loaded with 20.0 gr of 2400 over my own cast Keith 250 gr - usually H&G 503
but the 429421 and RCBS 44-250 K are also used.

Reading these above post , I just have to ask myself WHY? the 1911 45acp works very well just the way it is. yes its fun to play with other so called inprovements (a few more FPS). But if I had to trust a gun to save my hide I would rather take a chance with a gun that worked every time with 230 grain hardball than a (super whatever? ) that may or may not have problems running. don`t take me wrong , I like ALL GUN `S and calibers and like to tinker with them. a good 44mag 4 inch might be a better gun to use if you might run into a bear

[HeavyMetal]

fivegunner:
I think you ought to go back and re read Triggerhappy's post number 11.

Not to beat a dead horse but his reasons made real sense. Basically once a stuation goes bad we all do as we are trained PERIOD!

Using the same type gun all the time increases chances of survival no matter what goes down. The chances of having to use a weapon weak handed or picking up a discarded weapon are non existant and have never, to my knowledge, been documented in a police shoot out.

Carrying a 1911 with a little more power for those few outings in the woods once again makes sense, For Triggerhappy, perhaps not for the rest of us.

Glad you guys re visited this thread I am curious as to what Triggerhappy decided to do, perhaps he will re vist this thread and update us.

[tek4260]

Here you go. Thread is about 265 CP at around 1K from a 45 auto

[only1asterisk]

My understanding is that Power Pistol is THE powder in .45 Super.

I've never had much luck with Power Pistol under lead. It is the jacketed bullet powder of choice for sure.

[MtGun44]

I would assume that most of the developers are using j-bullets for .45 Super,
a friend loads this caliber and swears by Power Pistol. He does not use boolits.

I’m contemplating 45 super. Where’s the best source for load data? I’ve got a 230 grain hollow point mold and I’m not really interested in lighter weights.
Thanks

There's a lot of "45 Super" data out there on the net and a lot of it is well up into 460 Rowland pressure territory. I used a chronograph and limited max loads to velocities shown on Buffalo Bore's website. I worked up slowly starting with a slight incr in 45 acp +P data, checking velocity and looking for case head bulge ("glock bulge"). I've mostly used longshot and AA #7. I've experimented with both 45 Super and 460 Rowland. I don't push either one of them - plenty oomph without going to the edge of the envelope.

45 SUPER AMMO


ITEM 45S185

45 Super is externally/dimensionally identical to 45 ACP or 45 ACP +P and is designed to be used in 45 ACP semi-auto pistols that have been fitted with stronger than normal recoil springs and a shock buffer, plus a couple of other modifications. While you can shoot 45 SUPER out of some stock 45 acp+P pistols such as the Glock 21, HK USP, or the full-sized all steel 1911, you will batter your pistol if you do not have them modified to handle the extra pressure and slide velocity of the 45 Super.

To learn about the modifications your 45 ACP pistol needs to reliably and safely fire 45 SUPER, contact Garey Hindman at 936-402-3484. Garey is the foremost authority on 45 Super modifications/conversions for your 45 ACP and Garey performs such conversions for a living.


The below velocities were fired from my Colt Gold Cup Govt. Model (5-inch) that was converted by Garey.

➤ 1,330 fps -- Item # 45S185 - (185gr. Jhp)
➤ 1,235 fps -- Item # 45S200 - (200gr. Jhp)
➤ 1,131 fps -- Item # 45S230 - (230gr. Jhp)
➤ 1,133 fps -- Item # 45S230FMJ - (230gr. FMJ-FLAT NOSE)
➤ 1,090 fps -- Item # 45S255 - (255gr. HARD CAST-FLAT NOSE)

As always with Buffalo Bore Ammunition, we use real world firearms to give you real-world data and results.

All our 45 Super ammunition is loaded with flash suppressed powders so that if you have to fire in low light (when the criminal element is out) you will not be blinded by your own gunfire at the worst possible moment.

All three of the JHP loads were designed for anti-personnel use and for hunting small big game-like deer. The two solid bullet loads were designed for breaking large bones like a bear's shoulders or skull but will work for anti-personnel use as well if you need to shoot through cover like car doors or stick frame walls.
