Home Forums Hunting & Shooting Hunting Rifles Ruger American with a shallow chamber

What’s the details on your rifle( I assume)?

I bought some from Norma at an Ungodly price just to have a base line- they took my money 2 weeks ago but I’ve not received a shipping label yet.

There is none to be had at a brick & Mortar from Texas to Georgia along I-20. I stopped and/or called every place & on the maps I could find.

Thanks Hiden.

Have you tried going shorter than 2.795?

That is only .005 shorter than the SAAMI Max of 2.8.

I would go deeper before trying anything else. No harm in doing so.

No dice as in no marks in the Sharpie? Does the bolt close on an empty chamber? Rail screw a bit long?

Or on an empy brass.

I would also be interested to know where Hornady loads their factory loaded ELD-X Precision Hunter to as far as overall length goes.

Just looked in an older manual, not an ELD-X but they were loading their sleek bullets, SST & A-Max to 2.755.

Just food for thought.

Another thought, did you sharpie the shoulder really good and see if it is set back far enough?

Couldn't see it on my dark phone screen but it looks like the bolt is closed in one of your pics so disregard the rail screw thought.

You said left hand 7-08 and are sizing .260 brass, by any chance will a factory 7-08 chamber! I didn't read every reply. But I think that information is crucial, before any conclusions can be drawn! Or am I missing something by not reading all the replies?

H sell , mine is a Ruger American predator model in 6mm Creedmoor. It will not accept Hornady factory ammo either the 108 gr eldm or 90 gmx loads. Saami spec is 2.800 according to Nosler manual or Hornady #11. Ammo is loaded to 2.78" and will not chamber easily as the bullets are being forced into the lands. I put a round in and it came out sans the bullet with the action full of powder. Had to knock the bullet out with a cleaning rod. I put a round in my inertia bullet puller and whacked until I had the bullet far enough forward iron the crimp.out then seated by trial and error until it chamber easily at 2.69". That's .09" shorter than the factory ammo. It simply wasn't throated to the correct length. ...mb

I bought one for my son. I'll measure the chamber after xmas. You guys have me worried...

Wouldn't worry. There was another thread somewhere in here of somebody else having an issue w Hornady ammo.

Hornady factory not an issue for the OP but Hornady bullet.

Why would you make 7mm 08 brass out of .260 Remington brass?

I would use .308 win. and neck it down to .7mm 08.

I dont think its as simple as just running a .260 case through 7mm 08 sizing die and depending on the expander button to make things right...your neck thickness could be off. That's a hard push and pull for an expander button.

If it was that simple we wouldnt be having this conversation.

The "snag" is going to happen when he tells Ruger he was making 7mm 08 cases from .260 Remington cases and they won't chamber in his gun....

People at Ruger are going to think this is a prank call.

Same parent case, only difference is neck/bullet diameter.

I edited and added to my post after you captured it......there's a little more to it than it being the same parent case.

LFC is right about 1 thing the op needs to try some factory ammo before complaining to Ruger. Period. Mb

Are you saying the new Nosler brass being upsized could be off but down sizing it wouldn’t do the same?

I’m not sure I follow.

Norma finally Sent an email With tracking info so I’ll have some $3/ round Factory Norma ammo for a base line sometime this coming week.

That was my thoughts also: maybe LFC is on to something.

As long as they use the same receiver, they can ship it directly back to the owner.

Box up your rifle and call RUger they will come and get the rifle and probably have it fixed within a week and returned back to you.

Wrong. see my post
