.45-90
« on: October 07, 2006, 11:31:19 AM »
Does anyone know of a source for TrailBoss powder data in the .45-90? IMR has none and isn't responsive by e-mail.

Thanks

Try calling the powder co. tech. support number.  I used the 45-70 load data in my 45-120  and it shot so light I looked down the bore to make sure the bullet left the barrel.  I called about a year ago and they said they might work up load info. for more cartridge.  Got tired of waiting and will stay with Acc.5744.

I called Hodgdon Powder Co. today spoke with tech reference using Trail Boss in my Uberti 1885 45-90. His advice was lay the bullet next to the case, mark it with a pencil fill it with Trail Boss and that is a Maximum load. Multiply it by .7 to get 30% for a starting load. He also stated you could fill the case up with Trailboss and light it up and not cause any damage........

I read this before and didn't believe it until I called them myself.

If I agreed with you then we would both be wrong.

Trailboss is pretty hard to over charge.....but that doesn't mean it will be an accurate load.

You should have ask what kind of velocities and pressures you would get with that load...published  pressures seem high for the velocities produced.
