Lil Gun and Mid level loads with 245 Interlock

[cljohnson24]

Guy's, I'm looking for any experience with lower nodes using Lil Gun and the 245 Interlock/250 FTX. Running 7.5 primer/Horn case. Bolt gun. Looking for advice on how low I can go with LG and maintain decent accuracy, Or is this powder simply not going to group well below the normal 37.5-38.0 grain loads?? Hornady manuals says 25.2 is starting load and good for 1700, and that's more than enough inside 100yds for my 16 yo to take deer, but I also don't want to waste time and powder if Lil Gun doesn't do well with anything besides full power loads.
