M1 Garand Slightly Under-gassed

Normally been running stout Hornady 178gr ELD-M or Nosler 175gr RDF loads. Ran some light 125gr Sierra TNT's and needed to open the gas port two more clicks. Love this M1! Want to put a scope on it, or maybe some National Match sights. I don't get on well with the giant front post & 4 MOA adjustments of the stock Garand sights xD

Load is:
125gr Sierra TNT
47.9gr 8208 XBR
Lapua case
WLRM primer
2.75" COAL
