my pro hunter shot BH209 great.. best groups ever with 115 grains! My problem was a hangfire 3 days into the hunt. I keep all my parts spotless on my encore. Clean the breech like its gonna melt LOL. I went back to T7 after that.. BH209 grouped about 1inch better and I miss using the stuff. I just dont want to get a hangfire again. I had no issues what so ever testing out of 30 shots.. but the one day of the hunt I decided to takema buck it hangfired and the sabot went maybe 10 yards and thumped to the ground..
