My figure float border is always larger than the textwidth

Question

My float border, regardless of the image size, is always wider than the textwidth. Reducing the textwidth percentage simply makes the vertical size small (as it keeps aspect ratio) but does not make the float border any smaller See image, note the border extends beyond the textwidth:

Welcome to the site! It would help if you made your example a document that people could test (removing presumably irelevant packages such as lipsum, csquotes etec, and using ``example-image` as the image name (which is a sample image that most people have already in their tex distribution) — David Carlisle, Nov 19 '15 at 09:02
unrelated but \newcommand{\at}{\makeatletter @\makeatother} is equivalent to \newcommand{\at}{@} — David Carlisle, Nov 19 '15 at 09:03
Is there a suggested protocol for uploading an example document? — Doctor David Anderson, Nov 19 '15 at 09:12
Weirdly in the example image, the border is going wider than the textwidth. This perplexes me. — Doctor David Anderson, Nov 19 '15 at 09:21
In the complete document as posted in the edited question the border is textwidth exactly. — David Carlisle, Nov 19 '15 at 09:28
I suspect it is the trim=0cm 0cm 10cm 0cm which is forcing things, try deleting that. — David Carlisle, Nov 19 '15 at 09:29
It's certainly something to do with \floatstyle{boxed} it just is stubborn and refuses to make it fit around the image when the image is scaled. Apparently it is a problem with floatstyle http://tex.stackexchange.com/questions/25016/figures-with-borders-problem http://tex.stackexchange.com/questions/32457/make-all-figures-and-tables-framed-by-default But why does it work fine in the sample? I do not know. — Doctor David Anderson, Nov 19 '15 at 09:42

The float boxed style is always slightly wider than \textwidth. If you don't want the box around the caption, just put an \fbox{..} around the image.

\documentclass{article}
\usepackage{showframe}
\usepackage{mwe}

\begin{document}

\begin{figure}
\fboxsep=1em
\fboxrule=1pt
\fbox{\begin{minipage}{\dimexpr \textwidth -2\fboxsep-2\fboxrule}
\centering\includegraphics[width=0.8\textwidth]{example-image}%
\caption\blindtext
\end{minipage}}
\end{figure}

\end{document}

Here I implemented everything as an environment.

\documentclass{article}
\usepackage{environ}
\usepackage{showframe}
\usepackage{mwe}

\NewEnviron{boxedfigure}[1][]%
{\begin{figure}[#1]%
 \fboxsep=1em
 \fboxrule=1pt
 \fbox{\begin{minipage}{\dimexpr \textwidth-2\fboxsep-2\fboxrule}
 \BODY
 \end{minipage}}%
\end{figure}}

\begin{document}

\begin{boxedfigure}
\centering\includegraphics[width=0.8\textwidth]{example-image}%
\caption\blindtext
\end{boxedfigure}

\end{document}
