I did a five shot group average with 5 targets of 0.875 and a best group of 0.63 . Type -99's are not inaccurate as a rifle , but are hard to get a good group average with the large peep sight . I can cut my groups in half with a small hole clip on aperture for the rear sight . 6.5mm rifle are all over the board on what bullet and load they like depending on bore size and what type barrel they have on them . The 7.7mm's seem to fall into two groups , chrome bores and non-chrome . In most 7.7mm rifles the Hornady .312 150 sp in the best bullet , the .312 174 rn will help with some really large bore rifles . Speer bullets are bad and the Sierra's are just ok . With the chrome rifles it seems the faster you shoot them the better they shoot .

Also for the OP . Type -99's have large to extra large chambers and PPU cases are too small , plus dies make the case too small . You can see the soot ring around the case head where it was too small to seal and did not expand enough . Neck sizing fired cases with a 7.62x54r die will help .
bob q, Can you share some of your favorite loads with us? I'd like to know what other field tests were like. I'd love to visit you someday. I've seen all those nice pig hunting videos in Texas and I want to try a cast lead bullet for hunting. CA made hunting with lead bullets illegal.
