Trailboss Powder data

Does anyone have a PDF of the trailboss powder load booklet?
Since it has been discontinued I can't find anything online.
Specifically for 44-40. I want to find velocity and powder weights.
Failing that has anyone had experience with this load?

Scroll down to find Cowboy Action loads where it lists Trail Boss and other powders with a 200gr RNFP bullet.

Gee, I don't even weigh trailboss anymore, I just fill to the bottom of the bullet seating depth (no compression) and all it good. I do this for 4 different firearms and the results are the same, easy comfortable shooting. In my opinion, easier for me to just load by volume instead of weight. I think I have 3 or 4 containers left, fun to shoot; I'll miss having it once it runs out.
I have some info on that powder laying around, I'll see if I can scare it up for you.

Thank you, I have a big jug of it which I was using for 30-06, and .223 😏, .
I have finally committed to reloading the .44 and find that they have stopped making AR2205 so I will use the trailboss. I have done a couple of loads and find that to fill to the base of the bullet is 7gr.

I just use my BP measures and load as BP by volume.

It's been discontinued? I just thought it was hard to find.

OK, officially it hasn't been discontinued, they just aren't making any in 2021 or 2022. There are letters from the factory posted online.

I still get it at gun shows and shops some times. The next time I see it for sale I'll probably buy as many as I can.

information: curiosity 🤓


People like to know what’s going on and Australian Munitions should realise that not communicating vital and timely information leaves individuals to speculate. As they admit in their own web post: “This isn’t some big conspiracy designed to short-change our Australian customers and, contrary to the rumours we hear all the time, no, we don’t ship propellant offshore to the USA to the detriment of Australian hand-loaders.”
There’s also been a bit of a shake-up in production and packaging of the AR and Benchmark series of rifle powders in that some are being released in different-sized bottles and others are not being manufactured at all this year. The so-called ‘popular’ rifle powders AR2206(H), AR2208, AR2209 and AR2213SC which are produced routinely and regularly haven’t been affected by any change, these propellants still available in both 1kg and 4kg bottles and produced continually throughout the year.
While AR2217 is outside the popular range it’s still made several times a year but will only be offered in 4kg bottles in 2021 as will AR2225 and AR2218. Benchmark 1 and AR2205 propellants will not be manufactured this year but there is stock of AR2205 for OSA and Winchester to access as required. AR2207, AR2219, Benchmark 2 and Benchmark 8208 will continue to be produced in 2021 but only in 1kg bottles for the foreseeable future.
