You shoot em the chest and they fall down. Is the verticle stringing with H110 a subsonic thing because I sure haven´t noticed it shooting supersonic with a long barrel?

I did buy a can of vv110 and a box of 220 matchkings to load subs. My new SSK Encore barrel came to the house the other day. Looking forward to seeing what I can do with the big bullets quietly. I will apply for the suppressor stuff and put a can on after this hunting season.

H110 strings mostly in subsonic loads.

I am about to give up using it for SS loads and it will be strictly for supersonic ones.

Watch for neck thickness and neck tension issues, especially with faster powders trying to keep sub speeds. The slower powders have time to build speed after the bullet has engaged the rifling and its less of an issue.

Measure the thickness if you can and shoot over a chrono. SD and ES numbers really impact groups when you're below the speed of sound.
