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?
 
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.
