1876 in 45-60 Trailboss powder loading data

[Slainte]

Could you please help me ?

I am shooting a Uberti 1876 in .45-60 with 300gr lead bullets.
So far I still have a bit AA5744 powder left, but cannot get any US powder here in Switzerland/Europe anymore.
Some kind of newer EU regulation with cancer stuff. Don't know the excat reason, anyhow lets not drift into politics.

I can get a Swiss made powder called RS 14 , which is made according to the producer to Trailboss specs. The producer recommended Trailboss loads minus 5% as starting base.

So to test that, I would need some Trailboss loading datas for .45-60

Thanks for your help.

So, the only question I see is asking for help. What help do you need, specifically? Trail boss loads? Fill the case up to the bottom of the bullet, no compaction, about 11.0 grains.

Yes, please give me some Trailboss powder loading datas for .45-60 with a 300gr lead bullet.

Thanks a lot

Slainte,

From the 49th Lyman Ed of Reloading Handbook (I do not have the newest Ed) it lists the following:

Lyman 457191 (292 grain) --- Trail Boss 10.5 grains - 1069fps  TO   14.8 grains  -  1256fps

Lyman 457122 (330 grain) --- Trail Boss 10.0 grains - 992fps   TO   13.0 grains  -  1098fps

Hope this helps and sorry it is all, I have.  I too loaded my latest casings with 5744.  With Trail Boss back on US retailer shelves, I am thinking of getting some, to try.

Let us know how you like your results, after choosing a load and shooting your rounds.

BRS

Thanks for the datas, will start with them (-5%) using the RS 14 powder.
