El-Lobo, you are think of the 1-11" twist being the slow one.

N.E.A. , if you are shooting those 15 shots one right after the other (especially through a sporter barrel) you could be heating up the barrel enough to cause the "stiff bolt" condition you are having.

Oil on the ejector should help as El Lobo stated. If it is really stuck, try some Kroil on it and let it soak and then try the tip of one of those vibrating engraver pencils on the ejector pin. Someone recommended that to me once and worked pretty well.

As far as a tacticool style stock, the Duramaxx is a great stock. Any of the Choate Ultimate Snipe, Ultimate Varmint, or Choate Tactical Stocks would fill the "tacticool" bill and help the shootability of the gun. Personally I am enjoying the laminate stocks I have more than any of the other types. The Hart LRT from Stocky's is a great one to check out.

Just a couple thoughts.
