I'm not a very good shot at all, but I do consider myself a good player - taking into account objectives and team support.
But I think I finally found a setup I can shoot with. It was always the panicked recoil that would get me, and I've tried dampening it with silencers and burst firing and all the rest but I still ended up shooting somebody's feet while they plugged me in the head.
So weirdly, it's less bullets that work for me I'm finding - but GOOD bullets.
M39 EMR with a holo sight (and that's important for quick ADS - I always ADS just can't change that habit) with or without a silencer depending on how the feel of the map is going. But here's the thing, I play with it basically as an **** rifle as I'm always at the pointy end of things anyway.
And as an **** rifle it rocks baby. If you have trouble with recoil try this setup (or maybe one of the other semi-auto snipers). It's smoooooth and really effective mid-range (real short range you got your Magnum, haven't you?).
Of course long, long range sniping I wouldn't try too often, especially against a sniper with a proper scope as he will win. But if you're in the front lines and want a quick smooth killer - use this baby as an **** rifle and she may just change your game and your aim completely as I believe she's changed mine.
