12" monster barrel and bolt

[Wethepeople]

Missed that rabiddawg, thanks.

guys see the bolder part. Removing the o-ring won’t help

Maybe not but we will never know if he doesn't check it.

My thinking is it's something to do with the o-ring creating to much pressure when trying too work with the harder steel caseing.

If the chamber works with brass cases then it should work with steel cases as well.

The only thing I can see causing the issue is the o-ring.

It's a quick test and will either proff irs the problem are that the problem does indeed lay in the barrel.

I need help I put together a 12" monster barreled grendel and it was getting hung up at first so I lubed and shot it to loosen it up and still having feeding issues with only steel case ammo.

10/4 but yes I haven't had any failures with factory brass only with wolf steel case.

It's short stroking will no pick up the next round.

Thinking about this. Often things will be tight when new and loosen up as the parts work into each other.

Works with other factory ammo but not Wolf.

Wolf is notoriously underpowered.

What if your gas system has some kind of blockage, as if the gas block was not well-aligned with the gas port?

This could explain early troubles with all ammunition, but then as parts worked in and the whole system loosened up, only the underpowered Wolf remained affected by some gas blockage, leading to short stroking?

Bolt works in another gun with a different gas system?

Double-check the gas system?

Then, again, doesn't explain multiple bolts fitting tight in an empty chamber....

If bolt-to-extension fit is too tight, I suppose that drag could slow down the carrier velocity enough that it shows up on underpowered Wolf, manifesting in short stroking.

Couple theories here. Will check when I receive it.[/FONT]

I sent bolt and barrel back to you I believe they should be there today. I looked at it before I sent it back it looks like the feed ramps are off

[Huckleberry75]

My 12" group buy bbl has a just a hair of overhang with the feed ramps. Bbl feed ramps stick out just a smidge past the m4 cuts in my LMT upper. It does not feed the Federal 90gn TNT factory load worth a rip. Meplates get hung up on the lip and it just jams the bullet into the case. Going to put the barrel into a Precision Firearms upper and see if it still snags /hangs over. The barrel is quite accurate and I love the weight / length, just need to sort these feed ramps out and it will be GTG.

You could probably blend the feed ramps into each other with a dremel and hone and then smooth them up with a soft tip and some polishing compound.

Or use shims to bring the barrel forward from the upper.

If it does the same thing with the second upper, that will most likely be my solution. Take it slow and polish it up with Flitz and buffing tip.

Here is what the feed ramps currently look like. Cutting lots of copper off the nose and gouging some of the side of the ogive. I may need to soften the corners on the center lug face that is catching the bullets as they go by to chamber.

Did you mention anything about magazines? Maybe one brand feeds rounds slightly higher than another?

Oh this is a "thing" I've noticed between brands. Some of my e-landers present the bullet tip darn near horizontal were my c-products have a bit more angle to them.

[BluntForceTrauma]

I hear ya. I've had to bend a couple E-Lander feed lips ever so slightly with a crescent wrench to get the correct feed angle.

Crescent wrench allows you to gently grip most of the magazine feed lip to bend it as a whole without bending just the tip and making it weird.

[Huckleberry75]

Running all E-landers. I will tweak one and see if it helps. I appreciate the tip.

[Huckleberry75]

Tweaked the feed lips and it seems to have improved from the initial feed with Chg.Hdl. Need to take it out for a little test drive.

As an aside, I took it to the range with my 95vmax/h335 hand loads and connected on prairie dog silhouette at 250yds, so that was fun.

Glad to see your getting it worked out sir. From what I seen when I was useing the elanders, the mags spring rate (force) was way way too strong. And that caused most of the feeding issues I saw with mine.

I did have to fix the feed lips on a few as well, but it was mostly the spring force causing the issues.

[Huckleberry75]

I left these loaded for a couple months and they seem to have broken in a little.

What ended up being the issue with the barrel???

I too, would like to know that!
