Loading Data for the 45-60 WCF

<< < (2/40) > >>

Silver_Rings:
Howdy folks,

Some of you are probably wondering about why I am working up loads that are this fast.  First of all I am having fun doing this.  I have shot my Chappy 76 more than any of my other guns , with the exception of my CAS match guns.  I have shot over 600 rounds through my Chappy 76 without any problems.  I pulled the side plates on it after my last range session and there is no sign of problems.  Once I get the speed that I am looking for I will work on finding the most accurate loads.

I figure the 45-60 in a modern reproduction can match the performance of Springfield 45-70 loads and that is what I'm trying to do.  With the 300 gr hard cast bullet I am looking for 1700 fps, which I have about reached.  With the 405 gr hard cast bullet I am looking for 1500 fps.

These loads have not been tested for pressure so use at your own risk.  These loads are NOT for original 1876 rifles.

They were fired in a Chappy 1876 reproduction with 28" barrel.

Brass by Jamison
OAL 2.26 crimped using Lee's professional crimp die

Remington standard large rifle primers
alt 6100ft temp about 50

I'm now using a target in front of my chronograph and that has improved the consistency of the reading I am getting.

Loads with filler use a 1/2 x 1/2 x 1/2" poly filler

I've started work on loads for 405 gr hard cast lead bullets.

Joe Lansing:
    Does anyone have any experience using 4895 or 4759? I'd be very interested in loading info using 4895 and 4759.

RedBaron:
I am extremely reluctant to respond, but here goes. Since this forum's inception, I have read, and used, the under- powered loads  listed. Some of been so low that the bullet barely exits the barrel, if the ultra light powder charge (4198,etc) even ignites.
Fiirst of all, I have been casting (RCBS 320 GR GC), loading, and shooting a 45-60 WCF for nearly 4-years. Several thousand rounds.
The toggle-link (modern repo) is not nearly as weak as some think it is, or as strong as some want it to be. Mr. Lansing asked about 4895. I have used that powder with good results, very accurate. The best ,however, is a slightly compressed load of H4831. After 500 + rounds of that load, I have found that it is by far the most accurate and consistent of anything I have tried. Before anyone responds, check out Ken Waters Pet Loads for cast bullets in the 45-70. Interpret from there, with common sense, of course.

Powders used with best results (with consistency,pressure, and accuracy as the standards):

1. H4831
2. 5744
3. H4895 (actually tied with 5744)
4. 2015

What is H4891? I've used H4831 and H4895 for years, but H4891 is a new one on me. Something I've been ignoring or...?

RedBaron:
Sorry. Thanks for pointing out my typo.  H4831..corrected.
