I have a 9.3x74R that I feel was damaged by Barnes X bullets. I shot 36 of the 286 Grain bullets through it and the rifle was taken off face. You can also see a 'shadow' of the rifling on the right barrel if the you hold it to a bright light in just the right way.

I can't say as a 'fact' that the damage was caused by the X bullets and I can't say for a 'fact' that the damage wasn't there from before. But I think it is true.

The interesting part was how fast it came off face. I was showing it to my friend before we went out shooting (Zebra culling) and he commented on how tight it was for a 70 year rifle. Three days later you could slide a business card between the standing breech and the barrels. It was while looking at it that he noticed the rifling impressions on the barrel.

Maybe a coincidence?

I spoke to Randy Brooks about it at SCI that January and was blown off with 'it must be a cumulative result, my bullets are the best thing in the world' comment. He was not interested in talking about it, I think he was afraid others might overhear.

Much the same as his conversation with 500 grains at SCI a couple of years ago about his bullets failing.

If you put your hands over your ears and jump up and down while singing it is hard to hear others talking.
