I'm thinking of trying the Predator Polymags (.25cal) in my new Sniper, but thought it best to ask first if anyone has already done so, with this setup. At $23 for a tin of 150 (plus shipping), it's a little pricey to just experiment. Any thoughts? It doesn't matter if they would fit the magazine well, as I probably would be doing single-shot-feed anyway. Also, how would they do for longer range stability ? Thanks in advance for your inputs.
