Looks like I got a short chamber

[LRRPF52]

I didn't call manufacturer because I was not sure the barrel was %100 short chambered and I didn't know if someone would suggest something that could be done to fix the issue , without me having to tear it apart ,ship it back and put it back together. Going from previous post it seemed likely my barrel is short chambered as the hornady rounds stick, wolf ammo doesn't. I also didn't notice any high pressure signs so I didn't know if I could shoot another 200 rounds and the chamber would open up a bit or if it was unsafe and it should be sent back right away. Which is why I was asking.

But I did also add that maybe the grendel 2 chamber wasn't as bad as people have made it out to be because there seems to be a lot of post around about people getting short chambered saami barrels. From what I gather the saami spec is best but it must be much harder to make barrels that are in spec with the compound throat.

There are several guys with unknown or Grumble 2 chambers who have contacted me via PM with short chamber issues, including excessive high pressure signs. Some are reluctant to send them back because they are shooting so well (this is common when the bullet doesn't jump at all). I've seen it on other cartridges as well with rifles I have owned or that people have brought to me, in .223 Wylde and .308 Win.

One particular .223 Wylde from one of the most renowned companies for making SPR profile barrels shoots lights out with 77gr and 69gr OTMs, but jams the lands and blows primers with M193. Owner asked me what he should do. My recommendation was either shoot the target ammo with longer ogive radii, or have it reamed so he can shoot the tangent ogive 55gr FMJBT fodder and possible lose the accuracy he has (shoots bug holes with 69gr SMK and 77gr SMK).

So this type of thing is not limited to any particular chamber. Another problem with the variant chambers that have no industry standard to them is that you're at the mercy of the reamer maker to tell you what the spec is, and they can and do change it to fit their interests.

How do we even know what the variant chambers are held to for throat length? They certainly aren't being held to set length in production, as I've seen them run anywhere from ogive contact at 2.250", to 2.340" with the same bullet. One would be fine from the mag with that particular bullet, and one has to be single-loaded to get even near .020" off the lands.

With a properly-cut SAAMI chamber, I can load everything from an 85gr Sierra HP Varminter at mag length, to 140gr AMAX at mag length, no jamming the lands.

All the 123gr bullets shoot great for me, as do 129gr SST, 129gr ABLR, in multiple barrels, all run at mag length COLs.

That's the whole purpose of the SAAMI chamber, to work well with a wide range of bullets when loaded to AR15 mag-restricted COLs.

If the leade is short in any of the cartridge chambers, you will see a certain bullet profile work well, usually more streamlined target bullets or shorter bullets, while longer and heavier bullets with an ogive that hits the lands early will jam.

If any rifle you have is this way and you want it to be able to shoot tangent ogives or some of the heavier bullets loaded to published COLs, you can have your chamber finish-reamed and polished.
