Can't speak to that particular bullet/ round, but even if there is copper fouling, just use some M-Pro 7 non-ammonia copper solvent to remove it. It's not a big deal to worry over.

I've ran nearly 1K of the 110 TAC-TX through my 10" BO, i haven't really noticed it being any worse than any other bullets.
I always clean it after each range session though so it sees maybe 100-200 rounds per. |

Iv shot ALOT of 62gr TTSX @ 5.56 pressures, and never had a issue.(1x8 twist)
Shot maybe 300rds of the 110gr 300 blk load and same thing. Never noticed anything (1x7 twist) |

Non issue. I’ve fired several 1,000s of Barnes bullets out of many rifles including 300BLK and have never had a single issue of copper fouling being a problem.

I may be looking at this wrong, but whether the interior of the bullet is copper or lead, the part that’s engaging the rifling is copper. So why would a TSX foul worse than a regular copper/lead bullet?

I've shot a combined ~460 TSX & TTSX bullets out of my 338 Federal Kimber Montana and 6.8 SPC AR. I've never really been concerned with copper fouling nor have I noticed any difference from my other guns shooting primarily lead. I wouldn't worry about it as long as you are half decent at maintaining and cleaning your guns.

Quote HistoryQuoted: Because they use a softer copper compound than a standard copper jacket. I think it used to be worse and they made a change at some point because in '12/'13 it seems there were more reports of excessive fouling with what I can turn up on google. Brass = Alloy https://en.wikipedia.org/wiki/Brass |

Who's talking about brass? Talking projectiles here.
Unless you're pointing out that jacketed bullets actually use copper alloys, not pure copper. Gilding metal, cupronickel, etc. |

Pure copper is very soft compared to steel, but it’s not like lead - you’re not going to scratch it with your fingernail. And it’s not going to “smear” or otherwise cause copper fouling just because...
Standard bullet jackets are made from gilding metal, a brass alloy of 95% copper and 5% zinc. The zinc makes gilding metal more elastic, and tougher. Pure copper is not very springy, which makes it seem softer, but it really isn’t. Worked copper has a Brinell hardness of about 100, while gilding metal’s hardness is about 114. That small difference in hardness is not enough to worry about. |

I've been unable to corroborate those posts on any other site but the ammo forum here moves pretty slow. |
