Lazzeroni-who buys them?

I wasn't saying they were not precision.

I was saying a sniper or match shooter would burn the barrel out in practice before they got tuned up real good.

Then have to rebarrel and start all over again.

This.

The 7.82 warbird pushes any bullet about 200 FPS faster than it's nearest competitors, the .300 RUM and .30-378 Weatherby. Those two are already way over bore capacity and eat throats.

I would be surprised if the best barrel could take 1,000 rounds of the 7.82 warbird without seeing significant throat erosion. 1,000 rounds is nothing for someone who is serious about precsion shooting.

As noted above, a PPC barrel is typically replaced at 700-800 rounds. A 6.5-284 barrel can last 1,300+ rounds, but it might need replacement after 1,000 rounds or less.

When winning or losing a match comes down to thousandths of an inch at many hundreds of yards, any degree of accuracy-degrading erosion is unacceptable. For anyone not in serious competition, the change in accuracy these BR guys won't tolerate would be far less than their typical deviation from group to group. An average, decent shooter would get many times more rounds down the barrel before he began to see a noticeable, consistent decrease in accuracy.

What RCmodel is talking about is a serious degredation, something you'll notice even as a casual shooter or hunter. Cartridges this overbore can truly ruin a throat in a few hundred rounds. The Warbird is burning more than 130 grains of powder behind a 180 gr bullet in a .30 cal bore.

I understand, not trying to pick a fight at all but "tuned up" depends on the intended use. I have a lot of hunting rifles that will likely never see 1000 rounds, even after I am long gone.

In any case I bet they would hold their own against a sabot round from a 50 BMG in accuracy, that would be the next closest speed demon.

.338/50 Talbot. 50BMG case necked down to .338 and "improved". Barrel life of about 250rds. Equals the velocity of the Warbird and a 150gn bullet using a 250gn bullet. And it's a target round.
