Yes, there is a logical step by step approach. If a case came out of a chamber it should go back in. If it doesn't after its sized, its a re-sizing problem. If the empty resized case will chamber but doesn't with an uncrimped bullet, its a seating problem. If it chambers loaded rounds but not crimped rounds its a crimping problem. The line between seating problems and crimping is a little blurry, but basically start at the beginning, break it down and stop whenever the wheels fall off.

Ok have been on vacation and have not been able to do later tests. Do intend on tearing the rifle down again to look over things noted in thread.
No I do not crimp the loads.
I started the handloading with the dummy round first, so I retested that. No primer in dummy round, the round loads, bolt in, good to go but as it goes click and does not fire, it's hard to see success or not. Will create another dummy round with the new SB dies.
Thanks guys. Appreciate your notes, hints and help.
Fall back plan is for her to shoot the factory rounds this hunting season. One shot should be all she needs after we redo zero on the scope for the new rounds.

Load a sized and primed case, pull the trigger and see if you get a clicking sound or a surprisingly loud banging sound. If the former, some or all of your wheels have fallen off. You might want to do that is a safe location, and definitely not when your wife is polishing the wedding crystal.

Many crimping problems are caused by people who didn't think they were crimping. The purpose of troubleshooting is to systematically eliminate possible problems, even those that you're sure are right.
How hard are you crimping the bullets? Are the case lengths all identical? Some times a hard crimp will bump the shoulder back and out causing a bulge in the brass. After reloading Mic the brass down the entire length for possible bulging.
If the cases are out of speck the chamber can resize the brass allowing a successful firing when re chambered .

I'm late to this discussion but will add a couple of comments. I hunted moose for quite a few years with a BAR in .270 Win. First off, I agree with the use of small base dies although standard dies set to cam over might be worth trying first.
With regard to stove piping I had this problem. Finally determined that I had gone way past the time for cleaning the gas system. (I did a lot of practice shooting with the gun.) After the gas system was properly cleaned up the stove piping problem was eliminated. From that time forward I made it a practice to clean the gas system annually.
These are great guns if you like auto loaders. I used mine for about 12 years before converting to bolt guns when I started to hunt in the western US.

My belgian 270 bar had the same issues . It cycled through federal blue box like a house on fire. But throw a full sized reload in her and it and Id have to use the bolt handle like a foreward assist. I just shaved a few thou off the bottom of an old full sizing die and it solved the problem.
