Barrel life

[Fuj]

do not understand how that would make it shoot better unless the rifling was gouged and the crown beaten with a hammer. I dont think you did that.
I would think if a guy thinks his barrel is shot out is to have a smith set it back some by cutting a new chamber and getting rid of the burnt throat.

That Wilson barrel in question, was originally just a recessed straight cut.

With a 10 power lupe you could see the crown edge was no longer sharp
but also seeing what looked like fine bead blasting into the muzzle. Bore
scope showed it better, and thus the decision to cut and re crown. Simple
do on my end being a retired tool maker, with lathe and Bridgeport set up
in my sons shop. The Wylde chamber itself still looked decent in my
opinion and the barrel showed no fire cracking to worry about. I do need
to get a reamer on the shelf, but it shoots good as it is......A little side note.
this particuler rifle has seen nothing but IMI Mod-1 77grain Sierras. Also,
if you don't have a bore scope with your tools.....Teslong is your friend.

In my experience, the barrel life depends on the number of rounds fired. I have found that if you are shooting long range, the barrel starts to lose accuracy around 500 rounds.

Ok I want to think all of the people that replied your suggestions help a lot. I am going to check a few things that I should have done before I asked. One more question I am going to order a another barrel just because I have the funds available and can wait to get what I want. So here goes with suggestions I normally shoot Berger 80.5 gr through a 1-7.7 want to get a 1-6 or 1-6.5 how much better do y'all think it will be for stability don't shoot less than .69? Let me know opinions as I have time to wait for what will work best for what I shoot target off the bench between 2-600

I cant imagine you will need a 1-6 or 1-6.5 twist to shoot 80 gr bullets. Twist rate selection is obviously dictated by several factor including but not limited to bullet weight/length and achievable velocity. I shoot a 7 twist and 90 Bergers @ 2825 fps in one combo and a 6.8 twist with 95SMK @ 2750 FPS in another. The freebores are pretty long and will force you to shoot the 88-95 class bullets unless you want to jump the lighter pills quite a bit. If you plan to stay in the 80 grain bullet wt I would think 7.5- 8 twist should be fine I dont see a need to go faster unless you want to shoot heavier bullets or will be shooting lower than normally achievable velocity

If you like the posts that answered you and/or you read a post that you like you can click the little "like" icon at the bottom. This lets the poster know you like it and read it. Good luck sir!!!!

All of the replies helped sometimes we get complacent and don't go back to the basics and that's what I did it is nice to have a form where you can ask a question and get answers from fellow shooters again thanks guys keep shooting

the lightest bullet I shoot is a 75gr a-max and the barrel I have will do that with absolutely no trouble the majority of time it's 80.5 Berger's I have a couple hundred 85.5 again Bergers the folks at Berger say that the 85.5 will shoot through a 1-8 that seems like a stretch to me southern precision has a 1-7 in stock a while back I spoke with the gentleman I think his name is Bob about the 85.5s he said he was shooting them through a 1-6 with a 30” barrel and had good luck at 1000 yds that seems a pretty good stretch for a .223 I just wanted a little feed back on the 1-6 and after looking at it I am going to stick with a 1-7 29” heavy target that will cover anything I will be shooting so thanks again

Basically, what paperpuncher said.
Twist rate is important. The faster the twist rate the faster the bullet spins - yeah, I know - duh!
But, if the bullet is spun too faster, it will have a greater tendency to come apart.
Hornady recommends their match bullets to have a max of 280K RPM; Sierra 260K RPM.
At the same time, the bullet needs to spin fast enough to stabilize. I haven't heard what Berger recommends. There are stability calculators at Berger and at JBM Ballistics.

The formula for RPM is RPM = MV*720/Twist rate
A bullet in a 7 twist barrel with a muzzle velocity of 2700 fps has an RPM of 278K.

So, you need to consider the MV of the range of bullets you want/expect to shoot through the rifle and see what their RPM would be with the twist rate and whether they would be stabilized.

I shoot 73 through 80 grain bullets and go with a 1:8, 1:7.7 or 1:7.5. I'm guessing that a twist rate that will stabilize a 90gr 223 bullet would be marginal for a 75 grain one.

you are certainly a skilled guy that knows what you are doing. I figured the rifling had to be damaged at the end of the barrel. how did it get that way? did it come from the factory like that?

4400 rounds total at match grade by the calculator assuming a number of things.

A .223 barrel can be destroyed in 500 rounds. Takes about one afternoon to do it.
It’s not nearly as much about round count. Rate of fire is the HUGE variable.

The time before last was shooting about a shot every minute shot fifty rounds and it was shooting excellent then last time was not pretty need to check a couple things then try again. But like they say a bad day at the range is more fun than a good day at work

Several years back I was in a local gun shop and he had a heavy barrel Savage 112 in .223 Remington sitting in the used rack. I was a little cosmetically distressed and we agreed on a price and it went home with me. I fit a new recoil pad and stripped and sanded the stock with the intent of refinishing it. While waiting for the varnish to dry I thought I'd scrub the bore and see what twist it might be. After I cleaned it, I put a jag and a patch back on the cleaning rod, got it started in the bore and measured between the handle and the back of the receiver and made a flag of masking tape to show me when I'd made one revolution. When I started pushing the rod through the bore I noticed my flag wasn't turning. I removed the jag/patch and used a larger/thicker patch thinking maybe the first patch was too thin to engage the rifling. The second patch had the same results, the flag only moved after shoving the rod in about 6 1/2-7 inches up the bore. A closer examination with a really bright light confirmed what I thought. The first several inches of that barrel looked like alligator skin or worse. How many rounds of .223 ammo would have to have been shot to do that kind of damage to a barrel?

Well went back shot some more at 200 today good news it's not the barrel it was the person at the other end me have to write it off as a bad day gun shot under 1 min at 200 that's good news bad news now I don't have an excuse to but a new barrel lol thanks for the in put from ya all

Don't just easier to justify. Buy it and have it on hand before they decided to tax the hell out of that next problem be best
