If you check in the Firearm Review Forum, under Rem.BDL SS280,you can check out some groups shot at 200 yds with Rem 280.One group really stands out but plan on doing a lot more testing,soon as I am able.I had a heart atack on the 5th and not going to be able to shoot for a little while(hope its just a little while).
My 280 is a bolt action,not a pump,but I do have a Rem in 742,in 30/06 and it is no slouch at hitting the middle of the bull,compared to a bolt.So the pump should with todays powders and bullets be close to the bolts in hunting guns.
Think you picked a good cal and rifle for deer or hogs.
