Uberti 58 Remington Cyl Conversion45schofieldloaddata

I have an Uberti 58 Remington Cattleman's Carbine in 44 C&B. 18" barrel 1:6 twist. Currently I'm using 30gr. FFFg behind a 136gr. ball. Drives tacks all day. Never Chrony'd it but I'm geussing approx. 800 FPS. I don't have a conversion cylinder yet. Maybe a Kirst. I have new Starline 45 Schofield brass.Winchester WLP primers.Hunters Supply 160gr.FP bullets.452 Dia. The best numbers I can find so so far is for a 200gr. bullet.40gr. FFFg. I'm estimating 28gr. FFFg for this load with regard to CUP. Any ideas? Thanks... s s

You will not get 40 grains of FFFg into a 45 Schofield case. That is a 45 Colt load, and even that is pushing it with modern solid head cases. My normal 45 Schofield load is 1.9CC (about 28 grains*) of FFg under a 200 grain J/P-200 Big Lube bullet. To figure out how much powder you need with your 160 grain bullets, determine how deep the base of the bullet will sit when seated.

Take your prospective bullet and line it up with the crimp groove even with the case mouth. Make a mark on the outside of the case even with the bottom of the bullet. Now make a little ruler from a small stick, with a mark on it the same distance as the mark on the case. Fill the case with enough powder so that the end of your little ruler is submerged about 1/8". That is your ideal amount of powder for that particular bullet. If you want to weigh it, go ahead and weigh it. If you have some sort of volumetric powder measure, set it to throw that amount. That's it. Fill the cases so the bullet compresses the powder by about 1/8" when seated.

* I said 'about 28 grains' because different brands of powders weigh different amounts. If you use my method to determine the correct amount of powder, you can weigh a charge and write it down in your notebook for future reference. However if you change brands or granulation, you will have to weigh it again to find out the weight for the new brand of powder.
