marcos0901 · Sep 1, 2024

My friend just built a 7mm Sherman short. We have n170,N565,h100,h4831sc, and accurate magpro. He is shooting 180 ELDMs He is using a 26 inch Krieger 1:8 twist.
does anyone have some good recipes?

Did you reference the load data on the Sherman Wildcat Cartridge website?

Yes just seeing if anyone had some pet loads.

In my 7SS for H1000, 180 Berger Hybrid, I started at 58.5 gr and settled in at 61 gr - started having pressure signs. I have some Retumbo data and IMR 4831 data as well.

Mine loves N565 for 168 Berger VLD-H and 175 Berger EH. I think somewhere close to what Para5063 said above. Start low and work up.
I am also going to work up a load with the 162 ELD-X. Likely same powder (I have about 6 lbs of it). All 3 are close in weight/length.

We started at 59. Working up. No pressure yet best load I have seen so far is at 62.8 and 63.4 of 565. I'm gonna play around with seating depth on those two charges. Started with the bullet at 2 thou off. The next round I made three just touching the lands made about a 1 1/4 group in a triangle. We should be able to get it dialed with the seating depth now.
