I have a new tikka 308 win. with a 20" bl. supposedly with an 11" twist. I have some win.760 witch Barnes says is fine for the 200tsx in a 308 winny. Problem is Barnes recommends a 10" or faster twist. This would be a 200 yard tops california blackbear load. Plus I'm bored. Anyone with experience in this load? How about anyone experienced shooting a barnes bullet at a slower twist, especially in a t3x that is recommended by Barnes?
