I have a bunch of ss109 pulled 62G penetrators that im trying to get loading data for. Can anyone help me out with some data for IMR 3031 or IMR4198

When I don't have load data for your specific bullet, I go with a similar constructed bullet. The SS109 has lead under the biggest portion of the bearing surface, so I would use these numbers as a starting point.

This is the data for a 62gr Swift Scirocco bullet.

62 GR. SFT SCIR IMR IMR 3031 .224" 2.260"
20.3 2700 43,500 PSI 22.0 2940 53,100 PSI

This is the data for a 63gr Sierra Softpoint.

63 GR. SIE SP IMR IMR 4198 .224" 2.200"
18.5 2756 48,100 PSI 20.0 2946 53,500 PSI

So starting charge 20.3 for IMR3031 and 18.5 for IMR4198. Hope this helps.
