It should be right on the nose at SG=1,40 from a 1:9" barrel going 1100fps.

When the mould gets here i can cast a handfull and mail to you.

Subsonic in the 17 squirrel is:
Below 1 grain of RED DOT
Right at 1 grain SOLO 1000 and CLAYS
And a whopping 1.4grain TrailBoss

Subsonic in my 17VHA is the same with the 32gr N.O.E., it puts a silly grin on my face using 1 grain of H-S700X. With 12.75gr H2O case capacity it is a happy, quiet, & an easy to load well mannered little cartridge. It does roughly the same with the old 25gr REM PLHP.

Solo 1000 is in the QL database, while H-S 700X is not. By your calculation using QL and my experience using the 17VHA 1.0gr of these powders both produce subsonic velocities in these two cases. Solo 1000 and H-S 700X both lie on the same line in the QL burn rate chart found in the QL manual. They even look a lot alike.

What do you suppose the calculated gain in ballistic efficiency of the 17 Squirrel compared to the 17VHA using your load in the Squirrel case and with the same 1.0 grain of Solo 1000 in each?
