My 6.8 shoots Silver State Armory 110 grain Accu-bonds flawlessly, however when I reload the same bullet, same overall length, I cannot get the gun to run more than a round or two without a stoppage.  I have been all over with the H335 powder charge, from min to max, same results.  Should be noted that the reloads are very accurate.

Any advise would be appreciated.

what do you mean by stoppage? not feeding? short stroking?
What is you max H335 load? I have run it all the way to 34gr with the correct spec barrel so I am just guessing here if you are following
the load data in a book then the loads are still light if you are having short stroke issues..

It would shoot and eject ok, it would just not pick up a new round, the bolt would close on an empty chamber.  I loaded H335 up to 29.5 grains, but then I started getting pressure signs.

What pressure signs are you getting?  What are the details on your upper and barrel?

16in bbl w/Midlength gas port position?

If you have settled on H335 as your powder, because of the accuracy, then you'll need to enlarge the gas port...which is at what measurement now?

Or go to a faster powder.

Go to RL-10X or H322

H322 is my favorite powder for the 6.8.

You probably should switch to RL10X (IMHO)...

What charge are you using?  I just bought some H322.

Thank you.

I've been using 28.0 gr with a Sierra Pro Hunter 110 bullet. Shoots just a fuzz over moa groups at 100 yds.
I think it will shoot better when I'm not shivering. I haven't chronoraphed it yet, Ill do that when the weather gets better.

edit: I should note that I'm using Remington brass
Winchester WLR primers and C.O.A.L. of 2.260 inches.
