My first impressions of the SR338 is that it is a DMR with all the sniper rifle scopes. I'm really surprised this is in the same category as the rest of the sniper rifles. This gun reminds me of the SKS from BF3.
This gun is definitely a DMR except that its only good for medium range. Up close shots and you need at least 2-3 shots to kill an enemy at point blank range. This isn't good at all for my style of Aggressive Recon. I don't see how you can get 3 shots off in time when it has a bigger accuracy penalty than a regular DMR with follow up shots. Any other gun could easily take you out in a fire fight up close.
