Finding The Wall
The loads for 44gr & 45 gr of LIL-Gun have a pressure limit as opposed to a timing limit. No Extractor or Ejector Marks and all rounds Extracted as Normal. The difference between loads is is a gain of 25.791fps for the 45grainers. Normal Case Head expansion should normally not exceed .oo15”. I do .003 on mine, but case life is much shorter. Recommend going to WW296 to find the Timing Wall/Speed..t
