No personal experience with the Bushnell, but I have had a lot of Burris #200293's (and still have a couple). They are great all-around scopes that fill the bill for many uses. I've used them for big and small game hunting, for predator hunting, shooting IHMSA big and small bore matches, and this older model 2-7 will take the punishment of handcannons quite well. Assume the newer model 2-7's would be about the same other than maybe the last one.
Never got around to trying any Nikon IER/EER's, but their UCC Monarch rifle scopes impressed me years ago and I started buying them instead of Leupolds, etc for my rifles. Had several Leupold pistol scopes at one time, but liked the Burris scopes better so they replaced them. Have heard good things about the Bushnell from folks who have them.
For the 7-30 barrel... a Burris 2-7 or 3-9 are solid choices, but so are all the others probably.
