So after some free time, I was able to test some more brands only slight improvement.
I took a little plastic off the stock in a couple of places and we are winning.
I went out today and shot a 13mm group @ 50 metres with out trying too hard.
I can probably get better out of it but I'm happy with that, I brought it as a bunny gun or some entertainment when camping. It was cheap and you get what you pay for in the end.
I appreciate the advice, Cheers.
