JGray: Well thank you for the heads up on the Win 40 gr PP's!
I have not had any troubles as yet with them?
When you say they "won't work in the tight chamber" do you mean they are inaccurate or that they won't function (fire, extract, eject etc)?
I definitely WILL be on the lookout for any troubles related to a tight chamber - I am assuming that perhaps all the 541's have the tight chamber you describe?
Thanks again.
Hold into the wind
