Now my greenhouse is finished (three connected end to end) it's not quite long enough for 10m but will easily accommodate 6, so my plan is exactly that (otherwise my Steyr is doing nothing).
I have been looking on the 'bay for target holder/pellet traps and it boils down to two styles.
Flat back or funnel type? Price wise there's not much between them and I am currently leaning towards the flat type because it will be easier to mount on my intended backstop.
What are your thoughts on both types please?
