Longshot? And a general hello.

Welcome to THR.

I do not have any experience in what your looking for but someone will be alone that may.

Howdy and welcome from Texas

Hogdon's website doesn't list any standard .45C loads with that powder but they do list loads for "Ruger - T/C" pressures. Looking at the data, there is only 9/10ths of a grain difference between min and max instead of the usual 2 - 3 grains. This tells me that the powder really isn't a good fit for this cartridge.

.40

LOUDShot is fairly decent for +P loads in 45Auto. That is nearly twice the pressure of the Colt.

There is a reason to call it that too.
Its in the group with Silhouette and Power Pistol for medium case volume pistol cartridges, accurate and boomy.

It’s been working for me in .38 special and 9mm. Not fond of it so far in .40 and haven’t tried it in anything else. Welcome to THR

Don't claim to be an expert handloader, but...
I bought a pound of Longshot to use with 10mm loads.

For .45LC I use Green Dot and a few others.

Get a look at any powder burn rate chart, and you will see that the powders for low-pressure loads like .45LC are pretty far up the chart from powders for higher-pressure pistol loads such as 10mm.

There are a lot of powders out there, and there is a good reason for that. While you can make just about anything go "bang", it is not always a good idea (and may end up being painful).

Powder is cheap.
Knowledge can be expensive, especially if you do not follow good advice.

As Walkalong said .... Longshot is best used at near full loads and it is a good powder when used that way ....I don't have any experience with it in your cartridge .... I really like it in my 357 SIG!!

Not recommending Longshot in .45LC. That powder is great in the .40cal, but Unique is better in the LC.

Where are my manners?

Welcome to The HighRoad, @chadzk25!
A clean, well lighted establishment!

Welcome to the forum.
First off the 45 Colt cartridge was made for use with black powder. It has a HUGE case. When using Longshot a little dab will do ya. A small charge range and what little there is floating around in there. First and foremost this will cause intermittent ignition problems. Then add the possibility of a double or tripple charge and nobody in their safety shoes will recommend it. There are many other safe propellants that will work and be economical to use. This is the reason you will not find data in any of the manuals.
I would use the Longshot in a newly purchased hand gun that I got specifically to use it up and stick with something that would at least half fill the case in those 45 Colt rounds.

Howdy, from Texas. I'm in the "Longshot no-go for 45C" camp.

I'm with .40_caliber and Walkalong. I used it in 9mm and it worked well for heavy loads. I can't imagine using it in a 45 colt with all that room around it.

Actually, LongShot is one of my go-to powders in the .45lc.

I started using it in the lc after reading an article by Brian Pierce in “Handloader” magazine. Like Unique, it leaves flakes in the bore and throws embers at low pressures, but for midrange .45lc it’s the best I’ve found.
11.2gr under a RCBS 270gr SAA SWC runs 1,120fps and is VERY accurate and is safe in the S&W 624 MountainGun. (per Brian Pierce) as well as the New Model Vaquero. In the article his son took a treed bear with it. It worked.

I find that load a bit much as we don’t have many grizzlies in Georgia, and our black bear are scarce in west central Georgia. My preferred load is 9.2gr under the Lee 255gr RFN for about 900fps from my 4” S&W 625.
From my 24”bbl Win. M94, I’ve driven the Lee 255 diagonally through deer and pigs.
I’m down to about a pound in my latest 8lb keg, so it’s time to restock.
Many newer powders have come along, but for its uses I haven’t found better. I use it instead of Unique or Universal.
For 9mm, heavy .38Spl, .40S&W, and .45lc, It’s unexcelled.
I’ve got two NRA PPC National Record certificates I shot using LongShot under the Lee 124gr .356” LFNC in 9mm. I’m sentimental...

I like PowerPistol too. My first lot# was labeled BullsEye-84. Predecessor to BE-86.

ps; I also use it for 20ga slugs, buckshot, and 1oz shot loads... .327 Federal...

These are NOT standard.45colt Colt SAA loads. However they are safe in NEW Modern actions and are only slightly above SAAMI published pressures which have been described as “burrito fart” loads... Use discretion if using...

2400 is my go-to powder for hunting loads in .45 Colt.

A very accurate load in my Bisley Blackhawk 45 Colt is the Bayou coated 225 gr. TC bullet over 10.7 gr. of Longshot with WLP primers. Gives right at 1050 fps and average of two 5-shot groups at 15 yards of 1.12 inches.

You might be glad you have it. For about 4 years there was ZERO pistol powder available during Obamascare I and II. It's a good powder.

It's a good powder for 357 sig and 10mm as others have said. Excellent for heavy bullets.
Just keep it, but dont use it for .45 LC

You might be able to find someone local that'll swap a jug or two strait across for something you can use. I would start there.

I use longshot almost exclusively for my 12ga handicap trap loads and love it for that.

Longshot in 9MM and .40 for me. Know it’s loud but groups pretty damn good out of my G19, 43X 9mm’s and Walther PPQ M 2 in .40

Yep, works great for 9mm
