Had a better shoot yesterday, found out some stuff -

This CBC M80 ammunition is a pain to eject the spent casings, or is it the firing chamber that needs attention? Had to palm slap the bolt handle hard to drag the stuck casings out. The steel case ones I used first did not have this issue. I seem to remember back in the 80's seeing guys shooting rifles by Swing having this same issue all the time.

100yd shoot, first 10 rounds missed the 9" paper plate target.... was sure I am a better shot that that??? Then checked the rear sight and it was set at 600yds, hmmmmmmm, sure I did not do that on purpose so I return it to as far below 200 as it will go and try again. Hit the plate this time at least but with just 1/5. Look again at the rear site and it is at 300yds. Turns out that with every round the sight jumps forward so without returning it to the bottom after every round it creeps ever upwards. For the last 10 shots I returned it back after every one and finally started to see a result on the targets, nothing to yell about yet but its coming. All were center or slightly off to the right, and one nice cluster of 3 in a 2" group.

I am REALLY not liking this blade sight arrangement and even taking into consideration the feeling I get here that the Ishapore 2A1 is not very accurate and 'Barney Fife's' choice of rifle I remain sure it can shoot well if given some love. I beg for guidance to fit proper ring foresight and an aperture rear!
