284 Win barrel life

Has any forum member shot their 284 Win to the point a barrel change was needed? How many rounds and what load.

A friend and I have built 284's for 1000 yard F-Class competition. He is of the opinion that barrel life is going to be over around 1500 rounds and I am thinking more like 2500. We shoot F-Class so they are shot pretty quickly (20-22 shots per relay) and usually around 70 rounds total in a day during a match.

My gun is shooting the Berger 180 gr Hybrids with 54.2 grains of H4831SC through a 30" long, 1.25" diameter, Kreiger 1:8.5 twist barrel. I clean you barrel at the end of each day at the range.

morn george,

i think you friend many be closer to the answer than you. having said that, that could go out the window it the bullet will take a lot of jump. 40-50 thou???

we don't know the answer to that question yet. also depends if you 'chase the lands'. and than add the 'max' jump - it could be a .140-.150 throat loss, [may need a 'throat' cleanup with a 'throater' along the way]. would it lose it's accuracy?? maybe so/maybe not. depends on reaction within the case with the bullet being moved out that far.

i only 'neck size' 1/2 of the neck +/- .125, so neck tension should not be an issue, but with the 'air volume' increasing, would 'that decrease' accuracy???

i am dedicating one bbl [brux, 1-8.5, 32"] to that 'test', using the very same load as you' have 424 rds through bbl and throat loss is only .0025 and is still a 'bug hole' shooter - 1/4 MOA. didn't clean the gun this past weekend and it shot better the second day than the first [day 150 rds down range]

pls keep in contact with me so we can compare notes - ronhermspnw@aol.com

will you be shooting at LODI in a few weeks?

My 5R Bartlein went south around 2000. I shot it a total of 2300 but the last 300 weren't all that great my X count went to almost nothing. Mine was shot exclusively in Fclass. It will all depend on cleaning habits and the particular barrel as no two of them are alike.
 
Ron - I have a 32" 1:9 Brux and will be at Lodi so we should talk. I have just over 500 rounds down the barrel so far, with Berger 180 VLDs into the lands using H4350.

jim,

roger that. will be staying at the 'bridge motel' in lodi. will be arriving on friday nite and shoot sat & sunday [18 & 19] before shoot. will pm my cell# to you.

RICK - BEST OF LUCK IN IRELAND & SCOTTLAND!! don't let DARRELL fill you with too much BS.
 
I,m on my 6th 284 barrel now.
1st one was shot out in approx 1500 rounds, but I spent half of that trying for too much velocity, using N560 and max pressures so I cant blame the barrel.
The next one was retired at about 600 rounds because it was a dog which would never shoot, showed no wear or erosion though.
3rd one was shot out in 1000 rounds (approx 200 shots were using max pressure) but was very very accurate, just a very tight bore. I freind hardness tested the outside of the barrel and said it was very soft, but when it was machined, apparently it machined like butter. Only 2" of barrel has fire cracking so I will be reusing it after cutting off 2" to 29" long. It would still shoot well for 12 shots or so, but that was it, it started spraying them.
4th barrel (a Shehane) never shot well, but I put maybe 500-600 shots through at very high pressure and another 400-500 medium pressure loads. It showed almost no fire cracking at all, but was a dog so I put it away.
The 5th barrel went very very well for over 2500 shots until a freind (I use that term loosly) machine guned 96 shots through it before a big shoot. (another story).
Borescope showed little erosion before the machine gun event, but had bad throat erosion for 2-3" after that. I cut 2" off, rechambered to Shehane and accuracy came back and I have got another 1000 rounds out of it and has only just started to lose its accuracy. (Very few hot loads through that barrel).
6th barrel only has a hundred fireforming shots, 60 or so max pressure loads and 24 medium loads so I will see how its life goes in a few years.
My medium loads were H4350 at 2700 or 2830 fps.
My max pressure loads were either H4831SC or VV N560 at 2900+ fps
Talking to other 284 users, it seems hot loads cut the life a lot, but different barrels are softer or harder than others and some barrels just erode a lot quicker than others. On average peak accuracy is 2000-2500 rounds
 
[QUOTE = "Travelor, post: 35961386, member: 135122"] ¿Algún miembro del foro ha disparado sus 284 Win al punto en que se necesitaba un cambio de barril? Cuántas rondas y qué carga.

Un amigo y yo hemos construido 284 para una competencia de clase F de 1000 yardas. Él es de la opinión de que la vida del barril va a ser alrededor de 1500 rondas y estoy pensando más como 2500. Disparamos a la Clase F, por lo que se disparan con bastante rapidez (20-22 disparos por relevo) y generalmente alrededor de 70 rondas en total un día durante un partido.

Mi arma dispara los híbridos Berger 180 gr con 54.2 granos de H4831SC a través de un barril giratorio Kreiger 1: 8.5 de 30 "de largo y 1.25" de diámetro. Te limpio barril al final de cada día en el rango.

I just got done replacing a 284 barrel with 1450 rounds on it. Things started to go downhill on this particular barrel about the 800-900 area. Fire cracked pretty bad for the first 5 inches. Shooting 54 g of H 4831sc and 180 grain hybrids. Trying a Brux now with the one in eight twist,we'll see how this goes.
 
I got 1800 out of mine and it still shot just over 1/2 minute. I ran 8 lbs of H4831 through it and finished it off with H4350. Bartlein 8.7 twist.

EXACTLY!
I couldn't have said it better myself!

And I've been pondering it for the 6 1/2 years that it was dormant
 
Depending on your load and velocity will determine barrel wear. H4831 running around 2800-2850 with the 180s guessing 2000 will be your number. 1500 -2000 with hotter loads and Reloader 17. Get what your looking for from the barrel and don't look back . Barrels aren't crazy expensive.
 
For big matches, my barrels are retired before 1,000 rounds. I'll shoot it to maybe 1,500 rounds for local matches and it'll go on the classifieds afterwards. Barrels are truly like tires. I don't want to run a tire to the point the tire is about to come apart. Same in a barrel. There is too much risk in having a barrel go out in the middle of a match (or in the middle of a lap in the case of tires), especially a big one. Keeping a barrel under 1K when entering a big match ensures I don't have this problem. Plus, the barrel is at its most accurate under 1K rounds anyways, IMO. If the barrel shoots right off the bat, I have no problems taking it to a big match with less than 200 rounds on it.

FYI, I shoot a 284 Shehane in both Brux and Bartlein barrels. Typical loads are almost always around 2800-2870 fps with 32" barrels. Having shot this setup in 8-9 barrels so far, load development is a breeze since my load is nearly the same from barrel to barrel.

I have had maybe 1 or 2 barrels that did not shoot as well as others. Those typically get used to about 1K in local matches or fireforming and they go up for sale rather quickly. No point wasting ammunition and time trying to get a barrel to shoot. If it doesn't show signs of a good barrel off the get-go, then it never sees a big match regardless.
 
I built myself a 284 years ago, right after Browning came out with the 1st A-Bolts. I've shot that rifle mostly at deer, coyotes, and groundhogs, and the past couple years I've noticed the groups are starting to open up from the usual 5/8" for 5 shots at 200 yards, to a now 13/16" for 5 shots at 200 yards. While I don't have an exact round count, I can come pretty close at an estimated 2,400 rounds. I've always loaded for optimum accuracy, and if velocity was up there icing on the cake, but secondary to accuracy. I've used different weight bullets, but long ago settled on 140 gr Ballistic Tips. When I rebarrel it, I'll be going with a higher quality barrel than the Shilen Select this time around.

Not sure what you mean by going with a higher quality barrel than Shilen Select Match as those are generally exceptionally accurate.

I am running Berger 180 hybrids through an 8 twist barrel with a MV of 2850fps. Both Bartlein and Kreiger tech guys tell me that I will start seeing an opening up of groups at 1200 rounds (which, for me, means any day now)
 
I got 1800 out of mine and it still shot just over 1/2 minute. I ran 8 lbs of H4831 through it and finished it off with H4350. Bartlein 8.7 twist.
That's awesome barrel life from faster than 9 twist. Goes to show how easy H4831 is on barrels when run at conservative velocities.
