Honestly, Varget is not really an ideal powder for the HAGAR (too bulky, especially for mag fed rounds where the bullet sits back in the case). Take a look at this link for load data with various powders:

You may seriously want to consider Benchmark - - here's some load info on Benchmark:
Note - All loads shot from an upper with a 28" Krieger 1:8" twist barreled upper with a HAGAR chamber suitable for highpower. The 105 - 108 gr. bullets were all loaded long for single loading only and all bullets less than 105 gr. were loaded at 2.340" OAL and used with modified magazines.
