I think a correct answer is largely going to reflect on what kind of "match" or competition shooting you will be doing. The problem isn't finding a rifle that will harvest deer or a rifle that will shoot at competitions, What you will have to do is find a compromise somewhere in the middle. I see that you stated most of your competition shooting will be inside 200 yards? If that is correct then you will not have a hard time at all finding a rifle that can do both. With this being said, I assume that you will want to shoot pretty accurate groups in your competitions, is this correct? Accuracy has alot more to do with practice and the set up of the rifle...ie..scope, trigger work, stock bedding ect. than it does with the actual rifle round itself. Also, it doesn't hurt to reload your own ammo if you are competition shooting, you will notice far better accuracy from your own reloads than nearly all factory ammo. When you are hunting, accuracy doesn't always have to come down to minute of angle precision. Thats why alot of guys on here will recomend getting 2 rifles. One for competition, which could be heavily modified with stock alterations and trigger works ect.and the other for just plain old hunting. Preferably you will want your hunting rifle to be easy to carry, so a "typical" match rifle would not be suitable for hunting. I use the term "typical" loosely because in your application for competition shooting, a 20 pound rifle might not be neccesary for you. You will see larger modifications done to rifles that shoot 600 meters and more. Like I said in your situation, these modifications might not be neccesary. Another thing, If you will be competing at 200 yards in these matches, then the shots you take at live game should not be much farther than that. This is because that is the distance you are used to practicing at. With all this being said there are alot of "GREAT" rounds that will harvest whitetail inside 200 yards and providing that you start reloading your own ammo these same rounds have been proven to give MOA accuray also. Here are a couple good rounds that would fit your quarry. 25-06, 7mm mag, 280, 308, 30-06...ect In my honest opinion I would choose the 25-06 or the simple .308 for competion and hunting, both rounds have track records in match competions waaaaaaaaaay beyond 200 yards and both have harvested their fair share of whitetails also. Regardless of what your choice is, with alot of practice and some mild modifications along with doing your own reloading, you should be bringing home trophies for the wall and venison for the table....good luck hunting and shooting bud....hope this helps.

Most benchrest competitions have a "sporting rifle" class. The rifles are usually weight limited, between 9lbs to 15lbs depending on the competition, sometimes a light barrel is required, sometimes heavy barrels are allowed.

And besides that point, there ARE factory production rifles that can be accurized to compete well even in 1000yrd competitions (not win, but at least compete-especially in light rifle competition, 17lbs or less). Remington 700P or the Savage 12 Benchrest being 2 of them. Get it in 300WSM, or 6mm-284. Both cartridges are competitive on the range, as well as effective hunting cartridges.

I personally use my own Savage 12 in .300WSM both for deer and coyote hunting AND for 1000yrd light rifle competition, as well as NRA benchrest competitions. It's 16.6lbs unloaded in the benchrest stock, but it shoots a 8" group at 1000yrds. I have a sporterized stock for it that I use while hunting (drop in action) that reduces the weight to 12.8lbs, off hand shooting is a bear but it's still possible. The only downfall for hunting is that my 12 is a single shot, but practicing reloads is a necessity for hunting AND competition, so it's not a problem.

If you want it bad enough, it's possible.

It's a compromise any which way you do it.

.270 Win or 7MM RM if it were me.

Yup!!!!!!!

I have read all of the entrys to this quarry and agree with most. That being said I will have to agree with OldBuckStalker1187 in the Savage rifle area. I have a Savage 112 BVSS-S in .220 Swift and just bought the Savage Palma in .308. LOVE them both!!!!!!!! My Palma rifle now holds a Schmidt and Bender scope and the 112 Holds a Nightforce. Both shoot sub-moa (Under 1 inch at 100yds) any day, every day, all day. Havent got to wring out the Palma yet.
I whole heartedly agree with the 308 round for both weapons. I used to shoot the 308 for work for 17yrs ( LEO Sniper) and have just recently went to the .338 Lapua in a Accuracy International AWM. I would strongly urge you to look at the Savage line for your choices and go from there. If you do not do a lot of walking for your hunting, mainly from shot boxes or elevated stands/platforms that require only a several hundred yard walk and then sit all day. Look at the Palma rifle and I feel with a set of good glass, rings and mounts, you will have all that you need in one gun. My .02 cents
