[QUOTE="el matador, post: 1040206, member: 12193"] Coopers are awesome rifles. I've got a 300 win mag Jackson Hunter that shoots about the same as your 280. I've done minimal load development with it and quickly found a 3/8 MOA load shooting 208 grain Amax bullets. I think with further load development or possibly a different bullet/powder combination I could get it shooting closer to 1/4 MOA. This gun has a great stock, crisp trigger, and a solid barrel/action. Not sure what I'd "upgrade" to since Cooper's are very good quality. A 24" barrel is about right for the 280 AI. You'll get another 50 fps or so by going to 26" but I don't think it's worth the trade off in maneuverability and weight. Brakes are fun, I have a mini magnum muscle brake on my 270 WSM and really like it. It won't help your groups much unless you're flinching but it will make extended shooting sessions more enjoyable. 1/2 MOA at 300 yards is not bad at all. There's no reason it won't hold that out to 600 or 1000 yards. Maybe a better scope would help, different technique shooting off the bipod, better rear support? It's also likely that wind is opening up your groups...are you getting horizontal stringing at longer ranges? [/QUOTE]
