Ok I’m looking for some education here with a long range rifle. Everyone keeps on talking about the 308 being a good reach out and grab you round. Sometime between now and next deer season I plan on buying a new rifle/scope. I’m planing on going with a browning a-bolt in 7mm mag. I have had a 7mag for a few years and really like that round, but haven’t ever went for any shots past 150 yards yet. I find myself wanting more and more to test and learn long range shots. In comparing ballistics and between the 308 and 7mm it’s seems the 7mm is a better round all together. The 7 is faster , more impact and less drop at all yardage. Now That’s what is on paper if I read it corectly, is there something else in the real world that would make the 308 a better round?
I seriously dought that in the field I will shoot past 500/700 yards and probaly wont go for a deer past 400. There have been a few times that I wanted to take a 600/700 yard shot at some bobcats and wild dogs but I usaly pass. I have hit a bobcat at 530 yards and I’m not worried about my ability to shoot. Also I don’t know shit about scopes either, so what would you guys recommend?

The .308 is cheaper and that means cheaper practice/range time. :D
They're really for two different purposes. If you're not hunting outside of Texas, there's not really a reason to buy the 7mm Mag. If you're going the A-Bolt Medallion route, and using it for 150+yd deer shots, 7mm-08 is the best deer medecine I've ever used. My cousin has one in that combo, and I've never had one move more than 10yds when shot in the 150-250yd range. My crazy cousin shoots em in the neck, and they just lay down. :D

I plan on going with this. I have always owned and liked browning shotguns and used one of these a few times and loved it.

I'd go with the .25-06 or the .270wsm in that model. G/L, bro!

I've shot a Remington 7mm Magnum for 20+ years. 7mm trajectory is much flatter than a .308 as it is being driven at much higher velocity.
.308 Win is based on a shortened .30-06 Springfield. Remington 7mm Magnum is based on .375H&H.
Remington 7mm Magnum shoots 139gr, 140gr, 150gr, 160gr and 175gr factory rounds and is a medium game rifle.
You can get 20 rounds of Winchester CXP1 150gr at Wally-world for 19$. With .308 Win, you can get bulk ammo, tracers, etc.
Belted Magnums are harder to accurize than a .308 Win.
.222 Remington and .308 Win are tops as far as "inherent" accuracy.
I think 150gr, 168gr, 180gr are pretty common for .308 Win with others available.
I think 168gr is pretty close to sweet spot for both calibers: 7mm Mag, .308 Win.
7mm is a .284 caliber. It is the next size down in common calibers from .30 calibers.
For .300 Win Mag, 180gr is pretty common.
.30 caliber rifles are very popular. Hence all the avail. cartridges: .300 Win Mag, .300 Whisper, .300 Jarret, .308 Marlin, .300H&H, .308 TC, .30-06, .308 Norma Mag, .300 RUM, .300 WSM, .300 SAUM, .300 RCM, .etc.
To me, it is like comparison of Crunchy to Smooth Peanut Butter. Depends on what you like. You may like both. You may like lunch meat.
If you are going to be a one rifle man, I recommend the .308 Win.
Both rifles are pretty big for Texas game.
Remington 7mm-08 is a necked down .308 Win to 7mm caliber.
.260 Remington and .243 Win are also based on necked down of .308 Win.

For scopes:
Shooting long distance. Look at BDC(bullet drop compensator) scopes.
I shot a long time with a 3-9 Tasco on that 7mm Mag. It held up for years in Alaska hunting of -35degrees. I have a Burris 4.5-14x44 now. bun
Burris, Nikon, Leupold are nice mid-priced scopes. These will run $200-$1000. Leupold has some models going into 2k range.
High-end scopes: Swarovski, Kahles, Schmidt and Bender, Zeiss. These run $1k-$3k. But you can get a nice Zeiss Conquest 3-9x40 for 400$.
Impressive hitting a bobcat at 500+ yards. Damn things get cocky during deer season when they know you ain't going to shoot at them.
Rule of thumb: Spend as much on scope as on rifle.
www.swfa.com has awesome prices and selection. They have a huge bargain bin as well.
