Dasher Troubles...

[Northridge]

I have had several X caliber 3 groove barrels through my shop, all have indicated in as well as the best makers. All bores have been right around the .237 mark all have shot small in testing from 100 yards to 1000 yards. All chambers were 6 dasher and & a mess of 105 class bullets, there not overly particular on what they will shoot. Velocity can start out a tad slow in break in but falls in to what I know in the first 150 rounds or so but never really fast so that is suspect. Something has to be being missed mechanical etc. Are you sizing brass enough if marginal this can be problematic. Could it be your simply shooting rifle to loose ? Sounds like you have been trying to narrow it down good luck. I would recommend .002th to .003th neck bushing under loaded round.

I've had about 6 dozen x-caliber barrels through my shop and you're right all have been as good or better than cut rifle barrels. All other barrels shot well from the start, that's why i know there's something wrong with this barrel. The action is a 40x bedded and pillars, there are no screws touching metal that it shouldn't be touching, the trigger is pinned to the action with no slop or movement. You get that feeling, when you just know it's the barrel.

Adam,

No grass growing under your feet. Looking forward to great results from the next tube.

Diagnosis is: it'll shoot 80s into a .5" group for five shots. Still won't shoot 105-108 bullets. It's an 8" twist, but it's broken imo. I didn't buy the barrel to shoot 80s, so off it goes. If the guys at X-caliber will take it back I'll send it back. First barrel I've had that has done this.

It's like buying a car that is supposed to get 35mpg, but only gets 19mpg.

What tube did you get ?????

Totally agree. That is just very strange that the 80 will shoot. I'm with you. If I wanted to shoot 80's I would order the barrel accordingly. Looking forward to your next one hole group.

Brux .236" HV @ 31"

I`ve got one here.......all smiles.....

That would be the inverse of the groves, which should be .243".

Checked the twist, it was good, 8" to the turn.

I switched the scope, torqued it all to specs. The stock and bedding have been ruled out with a dial indicator, trigger is secure. Still not grouping worth a damn. So a few minutes ago i put a tuner on it to try and slave it into harmony, still isn't happening. Groups are erratic and not repeatable. That to me is the nail in the coffin.

When you slugged the barrel the measurement you gave was that the groove diameter or the bore if it was the bore what kind of tool are you measuring with those things would help most people here conclude your problem.

That was the major diameter of the bore, i was using a .0001" caliper, not dial caliper either. But it was the barrel. The thing will shoot 80s like it's boring, just not any heavier.

All 80gr bullets, no load development, just 35gr of RL15 and a bullet.

Well you've got a nice varmint rifle barrel...
I wonder if the button slowed slightly at the muzzle end when it was rifled.

Thought that myself, I tried it out from both ends and it was equal with the patch and paper method.

Update on the barrel:

Called X-caliber this morning and the first words out of Hunter's mouth were "we'll have a return shipping label for you ASAP". They didn't have to take this barrel back as it shot exceptionally well for the lightweight bullets, but they did. Actions speak louder than words.

That`s good..........

Keep us posted.

Fantastic customer service!

 

[cj8vet]

not related to the problem but I am curious--you have 2 bolts for this rifle? or did you open it up from 223 size to 308 size?

Adam, I don't know why you would bring all this up on a public forum before contacting X caliber. They have probably the best customer service in the barrel business.

You should have figured there was an issue when you determined which pilot should be used for the reamer. I take it that you skipped that step?

 

[boltfluter]

I personally think this is a great opportunity for the manufacture to step up to the plate. And, they did just that. A win win in my book. I think Adam was just covering the bases to make sure he didn't have a brain fade. As we all do from time to time. Personally I see no malicious intent here.

I contacted them days prior to this post.

The twist is perfect, the bore is tight with no lose spots, all this has been stated in my previous posts, several times over. I guess you skipped that though. There's no abnormality that i can find other than it won't shoot heavy bullets, must have skipped that post too. Please, next time you go on a fishing expedition, do it somewhere else or read your PMs and the post before commenting.
