C.T. fail safe-nos. accubond-hornady interbond

[Gallahad]

 questions about all three, 30 cal. bullets

combined tech fail safe- for those of you who have used this bullet, can you tell me what effect the black coating had on your barrel, accuracy, etc.  does it make a mess out of your barrel, and do you need fouling shots?

nosler accubond- did it foul your barrel, and did you need fouling shots before a shooting session?

hornady interbond-same question as nosler accubond.

Thanks for any help you can give!

One comment: I think the fail safe is in a different niche than the other two. It's for maximum penetration on big animals. Expansion is slow to occur. The other two expand relatively quickly.
