Recently acquired a New M1A Super Match, Pre-Ban. I was helping a friend sell some weapons and I couldn't resist this one for myself, as I've wanted one for years.

I took it to the range a week ago. Shot some Winchester factory ammo threw it. I noticed the the Op-rod showed some brassing, where the rod was obviously hitting the empty shell casings as it was moving forward. Even nocking some of them into the walnut stock, marring the wood.... grrrrrrrrrrrr.

First thought was the factory loads were to heavy.
I loaded some of my own last week, using a military match 173 grain BT, and 40.3 grains of 748. Pushing it about 2275 fps. Figured it was slow enough. Went to the range today, and I still am seeing this marring.

Whats up? any help would be apperciated.

By the way,,,,,,,,,beautiful rifle!!!! Never skipped a beat and really groups. I have a new addiction!

Sorry about the duplicate post, folks.

I moved AUTOMATIC S&W's post from the New Member Check-in section before I checked here. Thoght he'd get a little more action on his question in this forum.

Ejection problem

The problem you are having is common. Many M14 type rifles even have the brass hitting the side of the stock. It's a matter of timing. The op rod is supposed to cycle fast enough to knock the brass forward at 1 or 2 o'clock. The common fix is to enlarge the gas port slightly. Before you try that, cut about 1 1/2 coils off the ejector spring and see if it helps. There could also be a problem with the "at rest" position of the op rod. Sometimes the gas piston holds it to far to the rear. Live with it or take it to a qualified armorer. These are not things that should be done by a hobby gunsmith.
