I’m considering a 1911 long slide and converting to either 45 Super or 460 Rowland. Goal is a 75 yard deer/hog gun. From what I’ve researched, it looks like either would get the job done. Leaning towards the 460 Rowland simply for increased terminal ballistics.
Curious if anyone here has experience along this path and willing to offer any guidance?
Thank you.

.460 Rowland is a great round. My Clark custom long slide in .460 is a killer on deer  |

Haven't got a Long Slide .45 (yet) but do have a 5" Kimber Stainless Target II in .45 ACP that has been set up to run .45 Super... It will run 250s at 1100 and 230s pushing 1200...a 6" will get another 50 fps..does one need more than that?
Also mine will run standard .45 ACP without even changing the recoil spring...
Kimber makes a Stainless Target Longslide in 10mm and .45 ACP with no firing pin safety. Picked up a LNIB 10mm for $750 at a local shop... Fusion also has a Longslide available in most calibers for $1200...

Appreciate the links. I’m leaning towards the Fusion if/when I buy. I’ve heard the Kimbers can be hit/miss on quality. |

Flat bottom firing pin stop and extra power MAINSPRING (26# or 28# I think) to retard the slide opening and a 22# recoil spring. Some also say the barrel should be fitted but the standard Kimber setup is running fine...and use Starline .45 Super brass.
Have owned four Kimbers...
Stainless Target II .38 Super with extra .45 slide setup
Stainless Target II 10mm
Stainless Target Longslide 10mm
...excellent fit finish and zero issues.
20 years ago had a ProCarry HD in .38 Super that would not run. It didn't seem that the slide was coming all the way rearward as it should...like it was not machined correctly. Finally sent it back to the factory and they sent back a new gun... My friend still owns the gun.
They got a bad name when they tried to change over to an external extractor ...which was a disaster...have a lot of friends with Kimbers and no issues...

I know historically Kimber had a "rough patch" where issues were an issue, but it seems most of that is well behind them. Likewise, I was looking pretty hard at Fusions as one seems to get a lot of gun for the money. Then I started running across reports from owners who had honest issues (fit and function) and the lack of customer support. That cooled my jets pretty quick. I'd like to find some folks who've purchased a late model Fusion as they do seem to be a LOT OF GUN for the money. |

I have a couple of 460 Rowlands (HK USP and 5" .1911). Pretty easy to get 1,100 - 1,200 fps with 250 and 265 jacketed/cast bullets without pushing it. The comp on the 1911 Clark Rowland conversion that I have is very effective. To me, the non comped 45 super has noticeably more recoil the the comped Rowlands. If you have multiple 45 ACPs the Rowland keeps you from accidently chambering a hot super in a standard ACP pistol. No fun with out pics - Frankin Rowland (modified Colt Delta Elite lower, Colt 1911 A1 upper, Clark Conversion). .  . Need some new sights but keep getting sidetracked. . Paul |

Putting a .45 Super in a 1911 not set up for it isn't going to break anything...just going to wear it out faster... Like running .38 Special +P in older .38s not rated for them...nothing blows up, just gets to the rattle point quicker...

Bob, Agreed if you are using loads produced by Buff Bore, Underwood or equivalent thereof. However, there is some really scary load data on the internet - here's one example: "As I posted earlier, I had an opportunity to have a few loads pressure tested by a friend in the industry. This was a limited opportunity and I only sent 3 loads for testing in their pressure barrel. These were the top three loads I'd previously fired in my XDm 5.25. All used new Starline 45 Super brass and Fed 150 primers. DO NOT USE THIS DATA ................... 230 gr. LFN, Montana Bullet Works, 1.230" OAL 9.3 gr. Power Pistol, 1155 fps, 33,000 psi avg. 275 gr. Hunter's Supply cast, 1.240" OAL 8.3 gr. Power Pistol, 1035 fps, 37,000 psi avg. 8.7 gr. Longshot, 1063 fps, 40,000 psi avg." DO NOT USE THIS DATA ..................... You could easily blow a case head if you get some of this 275gr HS of data in std 45 ACP pistols -- I've had "glock smiles" in HK USP with substantially milder loads. Not trying to be argumentative, just suggesting caution. Paul |

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.

The 230 grain load looks to be based on data that was released by Triton right before they went under. The Triton data uses the 230gr XTP over 9.4 grains of Power Pistol (Fed 150 primer, 1.220" OAL, 28k max pressure). I'd love to see those two bullets side by side. It might shed some light on a few things... -Rod |

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. |
