"Cowboy" loads

I'm loading a 255gr "Keith-style" SWC for a Thomas 1873 Revolver in .45 Colt.
I'm using Trail Boss 5.5 gr, max 5.8, at a depth of COL 1.595".

I'm not unhappy with the results. I'm just unhappy with the Trail Boss being distributed in 9-oz containers at $16.95 (better than local Cabela's, when they had it) which translates to $29.97 a pound.

Aggravated, probably to no avail, I lookd at alternatves and came to Unique, 8.5gr, at $22.98 a pound, and wondered if I should transition to this even though the bottom line equals 0.03 a round difference to my advantage.

Which takes me to this question: what are you all using to load a cast .45 Colt these days?
 
i use TB, Unique, and Win 231 in 45 Colt for cowboy loads.
all perform well for me, and I do not sweat the slight cost difference between the powders per pound.
My light plinking load is similar to yours, 5.8 gr TB under a 225 or 240 gr cast RNFP. I step up a bit power wise when I use unique or win 231.
 
For your 1873, it's tough to beat Red Dot. It's a fast burn rate powder that is not dense, so your case fill in that voluminous .45 Colt case will be good.

Thanks,USSR, I was thinking about a powder that occupied more space than TB or Unique.

To all: what's your experience with screws getting loose (more frequently than I would expect?)

I don't mean mine - I mean the gun.

Trail Boss

I don't think you're going to find anything that occupies more space than Trail Boss.
 
The 45 Colt is in the front line of my shooting and reloading since 1976, so I will share some observations:

First of all, in your gun, a replica of a Colt Single Action Army, more-or-less, right? If so, then do this: Get that Unique, get it while you can. 8.5 grains of Unique is perfect for your 255 grain lead bullets. It should yield right around 875 fps, + or -, depending on barrel length, cylinder gap, etc. You might be able to push it a little bit harder with Unique, and I do, but in my Vaquero, which is a stronger gun. If and when you need the most you can safely get out of your gun, I could suggest some other powders..... But your original post strongly implies an emphasis on economy, so....

With economy in mind, there are a couple of ways to go about it in terms of propellants: On the one hand, you could use a powder that is suitable to use at low charge weights, thus yield more loads per pound. In your application, Titegroup, Red Dot, and Bullseye will all run around 6.0 grains; green Dot around 7.0 or so.
And on the other hand, not all powders cost the same, so the equation doesn't always balance out the same cost per grain; you are looking at cost per loaded round. The reason I recommend Unique is that it gives the best balance of power, accuracy, and economy that can be obtained for the 45 Colt. Other powders can give you little more velocity than where Unique can safely go, but we're looking at burning perhaps 15 grains or so to do it, with so little to gain. if you could only have one powder for your 45, Unique is perfect. Having said that, in times like these, you could find yourself having to make do with what you can get.

I've tried a lot of powders in this caliber, some I liked, some I didn't; I'm currently using seven and I have some definite favorites, Unique being on the must-have short list.
 
Tried trail boss. Hate Trail boss. It's ok in small cases like 32long but it's lousy in 357 and bigger. I never could get a load I liked with it. I suggest you work up a load with Unique. It's an old favorite with 44mag and 45 colt cast bullet shooters and works pretty well and is accurate.
 
Since my RCBS powder measure hates Trailboss, I am not fond of that powder either. It does work acceptably with Lee powder dippers.
 
Unique at 8-8.5gr is very noticeably more accurate than anything in .45 colt I've tried using Trail Boss for several different firearms. I really tried to like TB, even purchased more last year with the intention for use with a conversion cylinder in a Remington NMA - but that setup even more so than than the others showed a huge preference for Unique. Can't really explain it but it is what it is I guess. I also had great luck with Red Dot but Unique is what I'm well stocked on, so I doubt I'll ever load .45 Colt with anything else. Other than black powder that is.

cdoc42,

Never said it would fill the case more than Trail Boss (it won't), but it's a much more versatile powder than Trail Boss, which is a one-trick pony.

With regard to screws...on my OM Ruger Blackhawks, I either use blue Loctite or screw a small piece of 10# monofilament fishing line into the threads. The Loctite is easier to deal with.

USSR, sorry, I misinterpreted your post based on your statement about density.

I loaded up 12 rounds with 8.3gr of Unique, just under the 8.5 max. Now if the rather constant 12 mph wind and 28-degree temp would change, I'll be ready to go.

Old School, thanks for the Locktite tip.
 
I think you will find that is NOT a "Cowboy load." 8.5 gr Unique has been the factory equivalent for a long time.

So true. And when you back down the charge weight of Unique for "Cowboy" loads, you have Unique operating at a lower pressure level than it is best suited for.

Oh, my. I'm going to have to go to the apology drawer again, it seems. I really wasn't looking for Cowboy competition loads, but just .45 Colt load for what I consider my 1873 to be - a "Cowboy" gun. I guess the quotation marks did not deliver that meaning Sorry if you all got pulled off track.
 
Yep, that 9.5-grain load is what the top BP loads came closest to. I read a book of Hatchers written in 1927 that mentioned that. 930 or 940 fps. Something like that. I don't recall the manufacturer.
 
My .45 Colt general purpose 250g RNFP load is 7.0g Green Dot. My chrono showed around 900fps out of a 5 1/2" barrel. Easy shooting all day type load. Works well under 255g SWC too.

While I still use Unique, I've moved away from it in the .45 Colt. Not that it is a bad powder, far from it, but powders like Green Dot, Universal, BE-86, 20/28, CFE Pistol, and True Blue I find are more consistent. Ie. I see lower extreme spreads over the chronograph. For reference, my ES for the Unique load I shoot was 59fps. For the True Blue load I shoot, ES was 22fps. That is almost a third of the Unique load. The Green Dot load mentioned above ES was 40fps. Now at normal handgun ranges, not a biggie... Still easily minute of tin can. But when you start reaching out there, ES becomes more important. The idea is to look for loads that are consistent... and accurate.

I should mention I still have lots of Trail Boss powder here too. But it sits in the back of the cabinet. I moved away from it as well. Consistency wasn't bad (30 to 40fps or so) but not really up to shooting at the velocities I like to shoot. It is a good powder to beginner reloaders though as you can't 'overfill' the case. If you follow the simple rule of 'never compress' your golden. Under fill is easy to spot, and a double charge overflows the case. For the Cowboy Action shooters I would think it works rather well if not messing with Black Powder.
