That is pretty ordinary, having to buy targets from the range, do you need to be a member to shoot at the range? Are you allowed to modify their targets with your own dots or mrks? Shooting is expensive enough. Are you shooting off a rest or using a bipod? Those groups around 44.5 look promising, might be worth a five shot group.
I'm a SSAA member anyway but I don't think you have to be to shoot there. Mind you its $30 to get in there and that includes 4 targets, extra targets are $1 each.
On my second set of targets I drew some extra dots on the target but they weren't big enough so was a bit hard to see at 100m.
I much prefer to just shoot out in a paddock, don't have all the rules there.
For $60 we get a 12 month range pass and can turn up 24 hours if you want. This time of year I shoot after work in the dark. No one cares what target you use as long as you leave the place neat and tidy. How much magnification are you using?
