Versatile
I have used this for years for Cowboy Action shooting.38/.357. Recently I inherited an 1874 vintage Trap Door in .45-70. I found a nice light load for 405 grain bullet at 925 fps. It makes the gun a pleasure to shoot. (Original load is 1200 fps. Gun is 149 years old and I am cautious.) Trail Boss meters well, is bulky enough to see in the case, shoots clean, and is reliable. Very pleased to find it here.
A Really Different Powder
To get free shipping and hazmat with my TiteGroup order I included a bottle of Trail Boss since I've been wanting to try it since it first came out. Loading it is not like any other powder as it has BIG flakes which makes it easy to set the powder measure in my Dillon 550. I've loaded different charges behind 200g & 255g coated bullets for my .45acp. This weekend I plan to target practice and see how they perform.
Allows everyone to enjoy shooting
I started using Trail Boss Powder after reading about it in a couple of Gun Mags. It sounded too good to be true! I have been an avid hand loader for thirty five years, and loaded for everything from .38 S&W to .458 Win Mag. I became interested in six shooters and lever actions while attending the armorers classes at Suzanvilles Lassen Community Collage for my Sheriffs Department. I started doing pistol smithing for friends and grew interested in Linebaughs .475 and .500 big bores. Even modest loads in those beauties wear on yer nerves after a full afternoon. So, TB allows mild but satisfying handloads even the grandkids can enjoy, and the fact that an overcharge is practically impossible to produce, makes it the perfect learning powder too. Kudos to the makers of such a fine product, that can only help to grow interest in my favorite sports!
FUN STUFF
Makes 44 magnum and 450 marlin comfortable to shoot. Good for young shooters that may be turned off by recoil.
Great for CAS
I had an incident with another brand powder when I accidentally double charged one case to which it split the case in the chamber of my rifle. As a result, I had to take it to a gunsmith to extract it. A fellow shooter recommended Trail Boss powder. I got some and never looked back. You can not double charge a .38 special case with Trail Boss because of its large cylinder shaped flake, it takes up a lot of room in the case. It is a good powder for competitive shooting because it burns consistently and is not too dirty. The powder feeds very well through my Dillon 550B. Because I do competitive shooting (CAS) I have not really looked into how accurate my groupings are. If I shoot at the target and I get a pinging sound of the bullet hit, that accurate enough for me.
Expensive but hard to find
Ridiculous price for 9 ounces but it was something I wanted and almost impossible to find. Supply and demand I guess

This powder is great for the application.It would be a safe powder for people who are new to reloading,to prevent doubble charges.my only complant is it should be in larger size=8LB. thank you william Brockman
Beware the seals and lids
It is nice that ADI finally produced enough to ship a batch to the US late August of 2025 as I was down to my last bottle for 308Win subsonic loads.
Of the four bottles I ordered, three didn't have the seals properly attached to the bottle. As soon as you unscrew the cap, the loose flakes of powder in the cap go everywhere. One of those three didn't have the lid screwed on right as it was cross threaded. Which means that bottle was not air tight. Powder in that bottle smells ok, but I have marked that bottle for extra load testing.
Discussing this issue online, others had the same issue. But at least it was available again!
