I tried to shoot those in my Optima, and they fit loose in the bore for some reason. I had to shoot with a dirty bore for them to even group. If I cleaned the bore, it would almost sound like a misfire but the bullet would barely come out. After about 3 shots I could start firing. I did this twice before I figured out my gun didn't like them and it wasn't going to be safe for that gun. I wanted to like the bullet, ended up giving over a box away. After looking at reviews, others said they had problems sealing off also. Maybe some of the older CVAs had a slightly oversized bore or something, I'm not sure. Anyway it looks like it worked good for you, good job on the doe!
Sooo. I bought these to try out of my Traditions G4 Ultralight with Blackhorn 209 since I was headed to Colorado this year.
Their legal blackpowder guns are full bore projectiles only, no sabots, loose powder only, and iron sights only.
I've never liked how powerbelts performed on game when compared to my 240gr 45 cal XTP's, so I tried these with the BorLok.
I can say in the traditions with 110 grains of Blackhorn, the gun goes off like a rifle, and is holding a nice 1.5" group at 100 now that I've got the Nikon back on it.
I've shot 3 with this load since last Saturday. Two were very big mountain does that fell in their tracks at 25 and 58 yards. The smallest of the 3 made it 15 yards from impact after a 70 yard shot. This has been the only recovered bullet after 3 high shoulder shots through both scapula's.
