Helping a cousin in law get into reloading for his Ruger American 6mm CM and showed him how to size the cases to the chamber then showing him how to establish the point where the bullet contacts the rifling.

It was at this point I noticed that was well short (0.158”) from where factory ammunition was seated to, he has been shooting.

The bullet tips are distorted from using a rod to free them from the lands, otherwise they will pull and remain in the bore.

Left, you can see contact is being made at that depth but they will chamber and eject. The center is one chambered and tapped out at factory seating depth, right is round from box.

Seems like an awfully short lead, anyone else have one they can marker up a bullet and see if and if so, where factory ammunition contacts?

I was mainly wondering if that’s how they intended it to leave their factory.?

I'm 99% sure I gave my buddy Dell a couple of boxes of those 103 ELDX's, let me ask him to measure the overall length that his 6 mm creed predator will take.... If not I'll see if I can get him to bring the gun with him to work tomorrow and I'll do it myself.

I'd say that looks like an awfully short throat to me though.....
 
I have American Predators in 308, 6.5CM and 223. I had a standard American in 308. I don't handload for 223, but I've had issues with loads that wouldn't fit the Ruger chambers that would fit in my other rifles in the same chambering. That is with all of them other than 223, which only shoots factory loads. Never had a factory load that wouldn't work in any of them though.

I had issues with some of the very long high BC bullets not even feeding from the standard 4 round magazines in my 6.5. I tried one of the 3 round magazines intended for 450 BM ammo that actually works much better than the mag that came with the rifle. My 308 takes the AI magazines and 223 uses AR mags. Those feed fine.

Based on my completely unscientific observations it is my opinion that Ruger cuts the chambers on those on the tight side by design.

I like the Rugers well enough for what they are. I liked them a lot better when I was buying the Predators for $350 and you could catch standard rifles under $300. IMO they are now over priced for what they are. They are accurate, I'll give them that.
 
Picked up the 6 mm today but Dell forgot to bring me the 103 ELDX is to test.... Only bullets I have on hand are 95 grain ballistic tips and they're coming out it 2.80 to the lands

I must say Ruger was much faster than I expected. 12 days, 7 business days from shipped to received back at his house.

Not sure how they got to the “no markings left on projectile when extracting live round though because this is the result he had when he checked. After getting it back, had to tap it out as well.

They also didn’t return the dummy round marked and sent with it. Makes me wonder who they have doing QC/return inspections and why they thought a new bolt and chamber polishing would help a rifling/throat issue.?

They gave him another RMA though, and said they will call him upon when they get it this time. Maybe a little conversation will help, I figured the photos and sample would have done it.
 
Just a follow up, they confirmed that their bolt swap and polishing didn’t cure the problem. Instead of repairing the rifle they want to send another to an FFL. They did say they would send the aftermarket stock back to him.

I am sure it is easier to grab another off the line vs find and rectify the problem on an assembled rifle but that doesn’t necessarily mean it won’t have the same issue, unless they have changed the process in manufacturing.

That’s nothing I didn’t know before and why I started this thread back in April, to see if that is just the way Ruger makes them or an anomaly.
 
That's frustrating!

I just bought a Ruger American Predator in .308 and noticed some of my reloads were a bit tight when chambered. I believe factory spec is 2.80 for OAL and I had to load mine at 2.77 for my rifle.
 
I had an American in .243 that I bought new probably 6 or 7 years ago. When new it was very hard to close the bolt on a Remington green box PSP Corelock 100gr standard hunting bullet. By hard I mean you could not close it unless hitting it with the base of your hand. I did not have any other ammo to try at the time. I took it back to my LGS and they shipped it back to Ruger. Took about 3 weeks but they replaced the whole rifle the first time. It's not the first I've heard of the Americans being tight.....
