Prosport shroud...again

I have a 11.9ft/lb 177cal prosport. Today my shroud end cap of my came out and the 1st baffle looked very close to the edge of the shroud about an inch away.. I tapped it back both back in and now it seems like my accuracy went to crap. Is there a preferred depth of the beginning of the baffles and how far should the end cap go in? Im in the US and I have a HFT match Saturday so your help is needed quickly.
