The 43 and 43.3gr charges were still too hot, producing sticky bolt lift. The 43gr group wasn’t too bad at .999”, and with the 43.3gr charge, eight of the ten went into .538”, but two “flyers” opened the group to 1.423”. Had 15 rounds of prepped brass left in that box, so loaded up five rounds of 42.4gr and 10 rounds of 42.7gr. I wasn’t impressed with how the 174s were grouping thus far, so also loaded up some 168gr Tipped Matchkings, which my hunting rifle really likes, and for a 168, has a really good BC with a .535 G1. For the TMKs, I was more cautious and loaded up ten charges, .2gr between charges, starting with 42.7gr and ending with 44.5gr, the charge my hunting rifle likes. These were just to find max, to give me something to work around. Before this range session, I wasn’t happy with how I mounted the scope due to reticle cant, so remounted it, this time to my satisfaction. This range session, I started with the TMKs, using the first charge as a sighter then made all the adjustment my zero stop would allow before grouping the next nine. The next nine of 9 different charges went into .495”, though by 43.7gr, bolt lift was getting sticky again. I then fired the ELD-VTs. These grouped better than heavier charges, but nowhere near as good as the TMKs did. This rifle definitely prefers the 168gr Tipped Matchking over the 174gr ELD-VT and once I finish up with this box of 174s, I’ll not be pursuing them further.
