I like the Tasco Varmint/Mil dot scope.Cheap but very effective.It is 6-24x.I hunt with 10x or less,but at the range you gotta have magnification....12x isn`t enough power for me at 100 yds shooting targets.These scopes are less than $100.Love the mil-dot system.

This is my 243

I haven`t shot factory ammo in centerfire for a few years now.Wasn`t impressed with it.But if I were to shoot factory....the Remington Premiere Varmint would be a good choice probably.Whatever you get,buy at least 5 boxes with the same lot number on the box.I would stay in the 70-75grain bullet range for varmints....I dont care for the 55-58gr bullets.

After swabbing out the bore and then DRY patching the rifle to get out all the grease/oil/solvents and you make it to the range,it is my advice(take it for what it`s worth) to take only the cleaning rod with a wire brush on it.Putting anything in the bore between shots changes point of impact.In fact....it might take ten shots just to burn out the solvents/oil etc you may put in the bore at home.Just my observations on my rifles.Other peoples rifles may be able to shoot well with stuff in the bore,but not any I have shot of my own.

Save your brass....you may take up reloading.And since your brass is all the same manufacturer and lot number you won`t have to buy a new bunch of brass to get started.
