Stalker 5 1

I experienced the same problem some time ago. The round was skewing off to one side for no particular reason, other than the fact that I just took it all apart for cleaning, then re-assembled it. It turned out to be due to the inner barrel not being straight to the outer barrel. Some barrel spacers (made by wrapping lx tape round and round the barrel) sorted it out nicely.

Lafta - I think you are right on this. I am prone on the ground, and the target is probably at a height of about 6 foot (I try and make my practice as near to the real-world as I can). This is probably the reason why the hop-up affects the round in a different way. Infanteer - I usually cock my leg to shoot. And I don't mean Hard Routine! Samurai - Thanks for your input, but I'm quite an experienced marksman so this is not likely to be the problem. All in all, thanks to everyone for giving a few minutes to comment on my observations. I think it means I will be making a lot of shots from standing (using trees for support) or from the 1st floor of any buildings. I've still got fairly good accuracy from prone position, it was just interesting to see if this was a well-known phenomenon or just specific to me. Good luck in your various endeavours!

Jedi_Master - When fitted, the magazine is flat to the weapon, so doesn't rest on the ground. I have experimented using a bipod and unsupported positions when prone, and can't see any noticeable difference between the 2. It still has poorer results compared to standing. I thought it could be due to the the eye relief and hold in different positions, but to be honest I only experienced this with an SA80 at much longer ranges (200m+), so shooting at 30-40m shouldn't account for the significant changes I have seen. Anyway, thanks again for your input.

Wow, I only posted a few minutes ago and already some replies! Thanks for showing an interest. In response; Rock-climby-Dave - Yes, there is an improvement when kneeling, but not to the extent of standing. I've not experienced a cut off point, but firing from 1st floor windows at places like Longmoor I still see good results. I've fiddled plenty with the hop-up, but if this was the issue it wouldn't be selective about firing positions. Proffrink - I might try lowering the target (or firing from an elevation like a slope) to test the theory. Sararathe - all the testing I have done is outdoors, unfortunately I can't find a 40-50m indoor space to use. They may frown on me using the veg aisle in Sainsbury's!

I've been zeroing my L96 recently, and have noticed something strange, I wonder if anyone else has experienced this; When firing at about 30-40 metres from a prone (ie lying down) position, I get a grouping of about 40cm with most of my rounds. But when I stand up and fire from the same distance, I notice that the accuracy improves massively, to the point that the grouping reduces to about 20cm. This is counter-intuitive, as I know from shooting real firearms (SA80, 307 target rifle) that it's much more difficult to hit a target whilst standing. It seems as if the added height of standing vs prone is making the round travel differently through the air. I hope I'm not being too technical, but is this the parabola of the round being affected by not having to travel 'up hill' to hit the target? Am I making this up, or has anyone else seen this?
