Need 45/70 loads with Unique & 2400

[hylander]

Looking for load data with 300gr. And 405gr. Boolits.
My 4th addition Lyman shows nothing.
Looking for about 1500fps out of my Marlin 1895.
And of course looking for top accuracy.
Want to knock steel rams down at 250yd.
Thanks.

You didn't mention what you are shooting, some of the loads will destroy a Trapdoor.

[Recycled bullet]

Lyman 50th does not list unique or 2400.

Do you have any 3031/4227/4198/varget/rx7?? Under 1886 Winchester and 1895 Marlin it shows much data for these above 1500ft/sec with 292/330/400/405 grain cast bullets.

Have 4198, but saving that for other applications.
I have lots of Unique and 2400

I will look at my books but will not be able to get back to you until tomorrow. I use unique over the 405g lee.

[Recycled bullet]

I have never done 45-70. However experimenting with 308/357/38/303 it seems to me 2400 is slightly faster than 4227.

Maybe someone with a pressure estimation software can see if calculated safety to 1500 velocity is reasonable with 2400.

I wonder why 2400 and unique are not listed in my book???

[hylander]

I think the older lyman 47th is supposed to have Data.
Anyone here that can post a pic of the page or pm me the data?

[NSB]

My favorite load for my 1885 and 1886 Winchesters is 24.0 or 25.0 grains of 2400 using a Rem 405g JSP bullet. My 1885 High Wall is a true 1moa gun (five shots) at 100 yards with this load (not a “wallet group”, a repeatable group).

Holy Cow!
I just found lyman Ideal Handbook #40 and Lyman 41st edition on my shelf.

[FergusonTO35]

My Henry single shot really likes 12.8 grains Unique with an LP primer under a 300 grain boolit.

[pworley1]

The Lyman 44 has the data you are looking for.

With my 45/60 I was using 10 / 12 grs of unique, with a 500 gr bullet, start low and work up...

Here's a ton of data for low velocity loads ( not just 45-70 )
http://www.gmdr.com/lever/lowveldata.htm

[Outer Rondacker]

I use 10.5g-12g Unique for a low recoil shots over the 405g lee bullet. Honestly I use 10.5g more often as I am cheap and just need plinking loads. Should find a lighter mold as it will use less lead and kick less.

[RickinTN]

I'll try to post pictures of the data from the Lyman number Three Cast Bullet Handbook. I don't think you can get to the velocities you want with Unique but probably can with 2400. The pick that doesn't show the bullet weight is 293 grains. I shoot 12 grains Unique with both a 405 grain and a 365 grain bullet for a nice mild load.
Good Luck to you!

Favorite loads of mine are 12 gr. Unique under a 300-350 grain boolit for 1100-1150fps. 400 grain boolits get 24gr of 2400 or 28gr of 5744 for about 1350fps. The 400 grain loads closely duplicate the the original BP velocity. You don't need 1500fps to knock over the rams, even the 300 grain at 1150 is reliable with a reasonable hit and much more pleasant with regards to recoil. I suspect the lawyers are responsible for the Unique/2400 being absent from the newer manuals, afraid of someone not paying attention and double charging a case. Seems today no one is responsible for their own actions.

[Rich/WIS]

You didn't specify cast or J bullets. Lyman 45th lists 300 gr j with 2400, 30 grs/1658, max 34gr/1870

With 405 J 27 grs/1355, max 32 grs/1582

[hylander]

Today I tried 21 & 22gr. Of 2400
Under 300pb and 405gc.
Not to bad, but 1 flyer in each group
Going to try the same loads again.

[Castaway]

Lyman 44th Edition link below has 292 grain cast and also 405 grain cast data using Unique

You can download the 3rd ed Lyman cast Bullet handbook for free.
Just Google it.
You can keep it in your memory, or delete it and download it again when you need it
You can also buy the thing from CORNELL BOOKS
These are high quality reprints for low prices many other load manuals available there as well.
GOOGLE THEM.

Tried loads again today.
No consistency in grouping

[chriskendziora]

Try a magnum primer once the load density is low you may need a little more ignition?

Don’t take offense, but grouping on a two piece stock can be problematic. It takes an understanding of what forces are being applied to the forend, stock, and rest shooing a two piece stock to get the best groups. I can shift POI on any of my two piece stocked guns simply by allowing my cheek to sit “heavier” on the stock, or “lighter”. Moving the point of rest can also shift it quite a bit. The best load in the world won’t shoot good if there’s any inconsistency in the shooting process.

I do better with 13 gr of unique and a 405 gr bullet in my trapdoor reproduction. Steel plates dont stand stand a chance at 300 yds.

Hello
Lymans Cast Bullet Handbook dated 1973 has loads listed.

292gr cast slug mold #457191
Unique start gr load is 14.5 grains at 1285fps but goes up to max load of 18.0 grains of unique at 1460fps.
2400 start gr load is 24.0 grains at 1350 fps but goes to max load of 30.0 grains of 2400 at 1680fps.

405gr cast slug mold #457193
Unique start load is 13.0 gr at 1110fps but goes to max load of 16.5 grains of unique at 1260fps
2400 start load is 22.5gr at 1240fps but goes to max load of 2400 at 28.5 grains of 2400 at 1510 fps

As another already mentioned if your looking for speed then best look at IMR3031 because a 292gr cast slug can be pushed to 1720fps and the 405 gr cast slug can be pushed to 1640 fps as max loadings.

Head ShotOf note the Uniqe data mentioned slides down too 12.5-17gr in later lyman books and disappears in the 4th cast bullet book altogether. 2400 isn't listed either I found an old Alliant book that had both listed in Cowboy data.
