Unique in 40-65?

[JohnnieDavis]

Good afternoon all. I'm looking to do some smokeless reloading for my Shiloh sharps in 40-65. I use unique in a 38-55 Rolling Block as well as a 45-70 Trapdoor. I don't see any published loads for unique in 40-65 nor anything on the web. I am imagining somewhere in the 9-13 gr range would work well for a 410 gr lyman 410663 boolit. Any input would be greatly appreciated.

I understand the whole little bit of fast powder in big case could equal detonation argument but don't think the above charge would be an issue.

folks been loading 10 grains of unique in different rifle cases for a very long time.

My preference is to use a powder for which published data are available (4198, 4895, 4227, etc.)? BigTed's advice will get you there too.

I use 11g Unique under a 300g lead bullet in 45-60 with a 3/4" square of single ply toilet tissue to hold powder against primer. Very light recoil and super accurate.

I shot a lot of Unique in mine but don't remember the load now. Start at 10 and work up and you should be fine. I used the 350gr RCBS boolit.

Stay away from the long heavy bullets with Unique. I used 12 grains of Unique and got very hard impacted leading just ahead of the chamber.

21-22 grains of SR4759 is much better and more accurate.

Thanks all for the replies!! I'd love to use 4759 as it was my go to powder. I am waning myself off of it because when they discontinue it I will just end up having to find another new load for it.

I am experimenting right now with 41 mag bullets sized 408 in my c.sharps 40/65. They weight @ 210 gr. I started with 8 gr. up to 12 gr. So far 12 grains is best, so I am going 12-14-16-18 next week, If I remember, I will let you know results. using Unique.

I use 15 grains of Unique behind a 300 grain bullet in my 45-70 with good results and no leading. When I acquired my 40-64 for whatever reason I started using 18 grains of 4759 with equal results.

let 'em discontinue and hoard all the smokeless they like - gimme black powder for my roller and sharps, as it was in the beginning and ever shall be. 8-) :smile:

for smokeless and 19th century replicas that can handle the nitro, it's hard to beat aa5744 and sr4759 - those are the top powders for the top long distance smokeless shooters. dang it all! use that 4759! :)
