Does anyone know the barrel life of a .22 br? Looking for life until loss of .4"-.5" grouping at 100 yards. Thanks
.22 br barrel life

There are two many variables here to give a comprehensive answer. For one, it's possible that this would be the best accuracy at the very beginning. While a 22 BR is accurate, it is less so than a 6 BR or 6 PPC. In the hands of the average shooter .5 MOA would be about right. Then it will depend on which bullet. A heavier bullet, meaning a higher pressure load will erode the throat faster.
You might tell us what twist and what bullet you intend to use and you can maybe get a clearer answer.

I've consumed 2 .22BR barrels with the majority of the work in P-dog towns. Both barrels would shoot less than .2xx when new and would still shoot less than .600 when I trashed them. The throats got rough enough to start damaging jackets and smoke trailing to the target. They both lasted about 3500 rounds. They will last longer than most people think.
Going for 88-95s with a 7 twist. Looking to this or a 22 bra as i already have 6bra dies.

Doesn’t surprise me at all.

So 6mm is more inherently accurate why? And where do we draw the .5 conclusion from exactly?
My shot out barrel will still shoot under .5 after rechambering. If the new barrel does not shoot close to .250 with a little load work I would be incredibly surprised.
Scoreboard. In nearly twenty years of benchrest competition I've never seen a single 22BR ...ever. Possible reason is overbore. Whatever the case, they are not as accurate as the calibers I mentioned. Don't blame me, it is what it is. You have a decent barrel, good for you. Although .5 isn't all that great.
Barrels that will agg .25 aren't all that common although keyboard shooters would say otherwise. Maybe I should clarify that. 2.5 MOA rifles in the hands of keyboard shooters aren't that common.

I have not been able to shoot out a .22BR yet. I have several with well ever 2500 rounds that will still shoot from .25 to .375 moa easily. They just keep on going. One of my all time favorite rounds. If a new barrel will not group in the .2's there is something wrong. At least in my experience.

Not trying to piss anyone off. But having a rifle that will accomplish an occasional 3 shot group in the .2's is far different than a rifle that will consistently agg in the .2's. I just looked up the results from the NBRSA Regional Match at River Bend in November. 2nd place went to an agg in the low .2's. The next 10-12 places were aggs. in the .2's. After that it was .3's and I think near the end some .4's. My point being, these are the most accurate rifles available handled by accomplished shooters and they are struggling to shoot aggs in the .2's. I'm not criticizing you are your rifle, but I'm comfortable saying that a 22BR with over 2000 rounds won't agg in the .2's. It wouldn't do that the day after it was chambered.I have not been able to shoot out a .22BR yet. I have several with well ever 2500 rounds that will still shoot from .25 to .375 moa easily.

Anyone shoot 88 or 90s with xbr in a .22 br?

Yes. Works fine. 7 twist here and plan to do some work with the 95s also. Have not done enough to make any confident conclusions. At some point I will put up my results after I am comfy with things.
Valid points, Rick, but it doesn't make the "keyboard shooters" dishonest in saying their rifles shoot 0.2moa. They just don't look at aggregates as the measure of how accurate their rifle is. They dismiss the occasional flier as a mistake or bad bullet and the bad groups when they feel like they aren't shooting well. They look at the good 5-shot groups from the good days and say, that's what it can do without me messing it up. Many well built rifles will shoot in the 2's with these rules applied, and it's not a dishonest approach to accuracy, it's just a different standard.
What kind of speeds are you seeing? Do you think an 8 twist would be ok with the 88s? I've got a 1:14 twist 22-250 that I'm bored with, so I'm thinking about re-barrelling to a fast twist 22-250 or a 22BR for a change of pace and like the idea of running as slow a twist as I can get away with.
Just for fun, Rick
:My 22-250 shoots 5 shot groups like this occasionally:
53gn SMK, 35.2gn IMR-4064, Winchester brass and 1973 RWS primers.
I've got to wait for the good days where all the flags are hanging straight down for it to reward me with these kinds of groups. Good days will net maybe 2 groups like this, but not consecutively. All too often, being a human being (a.k.a. keyboard shooter) and not a benchrest shooter, I start to pull the 5th one out as I get too excited about how well I'm doing. I like to dismiss that group and keep shooting, all the while confidently telling myself and others that my rifle shoots 1/4 minute or better (so I'm really just lying to everyone, including myself
).
