Re: Looking for the right scope and bullet for a 7mm rem mag
If you're only shooting to 600 yards this should be pretty easy. For the use and ranges you described the 160 gr Accubond or Long Range Accubond would both work well. As for a scope, I would not use a 4-14 sort of scope... I would opt for a 2.5-10. You want all the field of view you can get for thick foliage and 50 yard shots, while 10 power will get you way past 600 yards on deer size targets. I would also suggest you certainly don't need two guns for this.
Here's what I use for elk at exactly the ranges you posted.
270 WSM in an Allen Precision custom bolt gun, with a 2.5-10 Nightforce. Scoped the rifle weighs in at just 8 lbs. No problem with the short shots, and I have used this rifle to take numerous rock chucks between 5 and 600 yards. This rig has also served well shooting paper from 800 to 1077 yards. I am using 140 gr Berger VLD's, but from what I have been reading, the new long range accubonds are proving to be another good, high BC bullet.
An accurate factory gun will make a minute of buckskin rifle to 600 yards.
