Barnes 70gr TSX fouling?

[TacticalTaco]

I've been reading reports of the extreme copper fouling caused by Barnes TSX bullets in rifles. Some people are claiming their groups expanding from 1 MOA to 4-6 MOA after 30 rounds.

There are some articles claiming Barnes has fixed this issue with the introduction of grooves within the bullet to ease fouling and lower the pressure. Does this provide any significant relief of copper fouling or is the difference minimal?

Can anyone confirm just how bad these bullets depreciate accuracy after only 1-2 magazines?

Thanks in advance!

Damn man, you live on the boarder and regularly piss off the cartel?

What kind of range you planning to be shooting people in “self-defense”? 4 MOA is headshots at 100. 4 MOA is body shots at 600.

The bore of my main rifle I last cleaned all the copper maybe 3,000 rounds ago? Upon inspection with a bore scope there is still no excess copper and more importantly it shoot sub-2 MOA with about anything, and sub-MOA with handloaded match ammo. I typically shoot about 100 or so rounds of Barnes through my rifle before hunting season and I’ve never seen any notable degradation in accuracy.

I believe you’re over-thinking this.

There’s a military organization that issues ammo with this projectile. They shoot an eff ton. I doubt many use a copper solvent, and they definitely require their weapons to work for more than one mag.

Unless your barrel looks like a sewer pipe, you’re overthinking this.

Even worse, downtown Atlanta lol.

Thanks for the input, were those 3,000 rounds Barnes TSX?

Nope, but as I said I will shoot 100 here and there. Usually getting geared up for hunting and then actually hunting deer, coyotes, etc. Of that 3,000 I’ve shot a good 300-350 rounds of Barnes in the mix.

I plan on using the 70gr TSX in a KAC SR15 for self defense and hunting. I'm now unsure if these would be ideal for using mag after mag in a prolonged self defense situation.

Bwhahahahahahahahaha

Easy enough to test using your own rifle, I would think.

Maybe not these days, with the market like it is.

Well for one these days you can't even find any Barnes TSX at least not in 5.56.

Midway has been getting batches of 70gr 5.56 about once a month.
