IMR Trail Boss Powder

Registered Users do not see the above ad.

I am excited about the new IMR Trail Boss powder. This will be a bulk powder like the old shotgun bulk powders. This will work well in the .22 Hornet with cast bullets and the .25-20 and .32-20. The new Winchester .25-35 with cast is another candidate. Velocities will be low with lightly compressed loads. IMR/Hodgdon designed the powder to meter smoothly from powder measures including the Dillon press. The powder is intended for the Cowboy shooters but cast target shooters and hunters should be happy about it too.

Hodgdon/IMR response

"Trail Boss is designed specifically for low velocity lead bullet loads suitable for Cowboy Action shooting. It is based on a whole new technology which allows very high loading density, good flow through powder measures, stability in regard to temperature variation and most importantly, additional safety to the handloader." Quote from IMR website.

Their data includes:


I emailed Hodgdon Powder Company/ IMR Powder Company a copy of "IMR Trail Boss Powder" post, along with my comment: " I intend to use this new powder for light to moderate cast bullet loads in my 25-35, some 357 Mag plinking loads, and 45 Colt, and hope some data will be published so I can also load my 22 Hornet, 25-20, 256 Mag, 38-55, 45-70 (I'll interpolate 50-110 loads from the 45-70 data when published!).", along with: " I too was excited when I read the Shooters Forum "This will be a bulk powder like the old shotgun bulk powders.",... " and inquired whether this might be suitable for mild shotshell loads also.

Their response was:

Trail Boss is NOT like the old bulk powders. It is going to have very specific uses and is not a product which is good for experimentation.

The person on the Beartooth forum has never seen our Trail Boss and has nothing but his opinion of what it will do. His opinion is wrong.

Trail Boss should be used for what it is intended, lead bullet loads in pistol cartridges.

Wow, seemed a little short, almost nasty! I don't know whether they're just nervous about any liability, but I certainly wouldn't be experimenting - leave that to the experts! - but it seems reasonable that we use many shotgun powders for handgun loads, even low-vel lead bullet rifle loads.

Thanks for the heads-up (this one got past me, didn't know it was offered), does sound like I'll give that powder a try within the listed data. If they didn't want people going off on their own they shouldn't have skipped the .38SW or at least offered an explaination of why it was by-passed.

Well, they are right about that!

"Trail Boss should be used for what it is intended, lead bullet loads in pistol cartridges."

Thats where I intend to start.

" Wow, seemed a little short,"

It does, but I am not sensitive!

" I don't know whether they're just nervous about any liability,"

They probably are. I may have made it appear in my post that I would try to use Trail Boss by volume rather than with measured loads.
If we depend on the powder companies and the reloading manuals to work up data with todays powders for our lever rifles and cartridges we might as well use them for fence posts. None of these companies are going to spend time developing loads for the .307 or the .356 with todays powders. None of these companies are going to do anything new with the .25-35 when Winchester puts them out later this year. I have a 24" .32 Magnum TC barrel. If I asked a powder company for load data they would send me data developed for 2" barrels. This is no different than working with a wildcat for which there is no loading data. We use caution and work slowly. We'll do fine!

Sounds like a plan, Slim -

Methinks Hodgdon/IMR is very sensitive on the liability issue. The response probably came from their legal representative for issuance by the "Customer Satisfaction Manager" (boy, what a title!). This same response would have been given for every new powder brought out in this age of hypersensitive company lawyers.

I had bought a can of Trail Boss hoping to use it for reduced loads in a 30-06 and found no Data on it with DuPont. Being somewhat Adventure inclined I filled a case about 2/3, put a 200 gr Lee bullet on top and found this combo to shoot just fine. I don't have a Chrono so I can't even guess to the Vee. The powder burned clean and the primer looked just fine. The I used a 150 gr bullet also from a Lee mold, added a bit of powder and the results are just fine. This was out of a Rem 760 Carbine.

What was the recoil like with the 30 caliber BBF?
I have been meaning to buy some of this powder for reduced loads for some time now.

I happen to know Mike Daly a bit (had lunch with him at a SHOT Show) and can only say that his reply may seem a touch curt, but he isn't like that in real life.

It may be that he'd just answered 453 emails from guys either complaining or wanting to do idiotic things with IMR powders, and his "big smiley" supply had run dry. YOUR email may not have been so bad, but if you had traded places, maybe your reply to you wouldn't have been so nice, either. Not casting an aspersion either way here, but cut Mike a loop of slack. Dealing with the public is not an easy job.
To see my books and articles, just Google my name.

I had forgotten about this thread. Scattered all around this forum there is quite a bit of Trail Boss data for various cartridges posted by several shooters. Trail Boss works very well for light loads in bottle neck cartridge cases and fills the case well.
The one hard fact most of us learned quickly was that Trail Boss does not like being compressed. Case filling loads with the bullet just lightly touching the powder charge seem to work well - this is not load data, just a comment.
We have used Trail Boss in quite a few rifle cartridges with good success. I believe I prefer using light charges of fast powder in rifle cases but these require special caution on the part of the handloader and are not for the novice.
Forum Member John Kort shot quite a bit of Trail Boss and his information is scattered around the forum too.
He didn’t hurt my feelings; I don’t expect any of the main stream companies to spend a lot of time developing data for lever action rifles or their cartridges.

I would compare it with a 223 Rem or similar 22 centerfire at most.

The barrel was still slightly warm from shooting full jacketed loads, I fired about 10 shots with the cast loads and the barrel wasn't any warmer. I came up with the 12 gr by just pouring in powder until I had about 1/2 case filled, then I put it on a scale and came up with close to 12 gr.I also shot those loads from my Stevens 30-6 with a 22" barrel and they did fine. Depending on how accurate you want to be you can play around, I went up to 15 gr and found no signs of pressure etc.

I know it's an old thread, but when you are looking for answers and the information you find is inaccurate or obsolete it is frustrating.

Unfortunately, the people in Customer Service are rarely users of their own product and are typically departmentalized from R&D and Manufacturing.

You can make reduced loads with Trail Boss in almost anything.

Several months ago Handloader magazine did a article on this powder in rifle cartridges. Very basic proceedure too determine correct charge even for cartridges that they have no load recommendations.

Seriously thinking of trying a load in my 32 S&W -- you can find lots of load recommendations for powders in 32 S&W long but not so much the original. And I don't want to stress it....

I have a couple well used .32 S&W break tops. I load 1.2gr Bullseye on an 78gr Meister or LC bullet. They don't get out often. I'd like to develop some milder Trail Boss loads myself. I hate to do load development in an old revolver. Maybe I'll use the Ruger .32mag. Do you think the freebore would affect relaibility tests?

My neighbor shoots "half a grain" of Trail Boss behind a piece of 0 buckshot. You can find the basic principle in the Lyman manual. I haven't checked to see how much that fills the case. I know there are strict warnings against compressing Trail Boss.

He says some of his "shooting buddies" are just using magnum primers and a piece of buckshot with no powder. I havn't tried it. I know CB Caps work on that principle. Maybe it builds up enough pressure in that tiny cartridge. I would think bore diameter would have a lot to do with that one. I'd like to see it on a chronograph.

With that small a charge, there has to be a very fine line between getting a bullet lodged in the barrel and destroying the revolver. I'd want to confirm the bullet left the barrel with each shot.

Probably should have started a new thread ...

Trail Boss OK for .38 Henry?

I'm new to cowboy action, shot 2 matches. If I use trail boss powder in my Ruger Vaquero, will the same load work in my new Henry Big Boy? I'm shooting lead 125 gr rnfp. I want to stick with 38 special instead of switching to 357 mag. I guess a light load would be required to stay under the 1400 ft per second max allowed for the rifle. Thanks in advance.

I use TB for 45 Colt and 200g lead bullets.

I love it.

I wish they has something like it which gave a bit more punch.

One of the shooting mags did a review of Trail Boss last spring. I cant seem to find it.

Basically it said to use as a max-the case filled to the base of the bullet-NO COMPRESSION. That was good for lead or jacketed bullets.

When I get caught up with the beaver, Ill see if I can find it and reference tha mag and issue.

For thoser who have not seen it-a Hodgdon black plastic powder jar that usually holds a pound of powder (not full) is just about full with 9 OUNCES of Trail Boss. The 8 pound big one holds 5 pounds of TB.

Take a look next time your in the reloading section of your gunshop.

Trail Boss fill the case to the depth of the bullet, weigh the charge - that is the max load
You can start at 70% of that and work up to a load that is not compressed

loads less than 70% may be dangerous

That is the same data I saw in the gun mag. Worked fine in some 223s. They ended up about like a 22 mag.
