Shot my Grendel over the weekend. Pulled the scope off and substituted my thermal. Also threw my Omega 300 on it. The action cycled perfectly, although there was some discharge through the ejection port due to the increased back pressure. Did not experience any blow back to the face. Interesting chrono results. 123 Hornady SST factory loads averaged 2464 fps. The 100 gr Hornady was faster, 2731 fps, which matches Hornady’s quoted velocity.
