These look just like the Rocky Mountain Bullets and Chinchagas (what I’ve been using for several years). The 375 grain .375cal Chinchaga aluminum rebated boat tail is 1.97” long (the Parker listed as 1.96”) and really has a G1 BC of .8, which isn’t bad. You would have a hard time convincing me the Park’s BC is near the .938 advertised. I’m sure it is basically the same as the Chinchagas I’ve used. So far I have had exceptional accuracy our to some pretty far ranges and down right terrorizing terminal performance on game.
