    When building a sniper rifle (and wanting a common caliber) which would you use and why??

    I personally would opt for the .308... Less recoil, easier to shoot, more economical to reload, still 1000 yd accurate.

    I am having a really hard time trying to justify the 300 even though I want too!

    My stepson has a Rem 300 win mag and it is OK to shoot. I will take my RRA .308 any day hands down. My wife and kids will go out and shoot my AR10 with me every once and awhile.... because the recoil isn't so bad.

    i live in southern indiana,old country boy at hear
    drag man,i own three 110 tactical savage rifles,i have identical scopes,rings,and after market trigger assembleys.(no accutrigger at the time)they all have exactly the same trigger pulls,one and one half pounds. the calibers are 223,308,300win mag.if you are new to long range shooting then by all means start with the 223 or 308.the 300 win mag,although it is not anything like my 458 win mag is still a fairly hard hitting round.i think unless you are thinking about knock down power i would stay with the 223 or 308.it dont take much to kill paper. old semperfi

    you know i just came to that realization a few weeks ago and have been doing things i normally wouldn't!


    As to the OPs topic. If you get a 300 win your going to spend more on ammo and your shoulder will fall off and walk away after a few rounds from a light gun. Put a muzzle break on the 300 win. If you go with a 308 Ammo is cheaper its lighter on your shoulder and you can buy very cheep surplus ammo.

    Living in PA I doubt you will have much use for the extra range the 300 will give you. Unless you plan to bear hunt from one ridge to the next. Hell I have a hard time finding a place to shoot 500 yards around here.

    I think 308 its gonna be. I have a 338 laupua and a 308 I don't think I can justify the 300.

    Sounds like you have made up your mind.

    I will say, the 300 Win Mag will do everything the 308 Win will do, but not the other way round.

    If you are handloading, the 300 can be loaded to 308 ballistics, again, not the other way round.

    I like the 300 Winnie. Don't have on anymore, but liked the cartridge.

    Your OP was about a sniper rifle. No way the 308 will do a better job than the 300 Mag.. Not nearly as flat shooting nor as powerful.

    Personally, I think this is a bit of a misleading statement.

    The 300 Winnie will carry better ballistics (with the same bullets) no matter what the range, be it 100 or 500 yards.

    Can you make a shot at 500 yards with a 308 Win ? Sure.
    Is it easier to make that same shot with a 300 Win Mag ? Sure.

    As far as the addition power provided, well, some like more powerful cartridges than others.

    I use my wildcat .338 for pretty much everything. It kills Deer/Impala/Red Stag/Eland/Hartebeest/Waterbuck etc., at 100 - 350 yards without a problem (have not shot farther than 350, so can't tell past that distance).

    Admittedly, I like larger caliber, Mag. style cartridges. I had to design my own as I don't care for 'belts' on cartridges anymore (I know, I know, it's all in my head :cool:).

    Personally I think you are mistaken by what I said, not the other way around.

    I said "Living in PA I doubt you will have much use for the extra range the 300 will give you."

    Meaning...go with the .308.

    Then I said "Unless you plan to bear hunt from one ridge to the next."

    Meaning if you are going need knock down power at 1000 yards or more maybe then go with the 300 since it is more powerful.

    I do NOT see how what I said was misleading.

    This is Pennsylvania, not Tanzania and we don't really hunt bear from ridge top to ridge top I was just giving an example of hitting something and hitting it and also killing it.

    Well I am still torn. Just can't seem to make up my mind. I don't care about hunting with this weapon at least. I wanna build a easy portable sniper rifle capable of taking "people" sized targets out past 1000 yards. I know the 308 can but the 300 is probably the better tool. I have a 338 lapua but it isn't an easily portable unit.

    I AM NOT SAYING I WANNA SHOOT PEOPLE JUST LOOKING TO BUILD A MILITARY TYPE WEAPON THAT IS ABLE TO.

    It depends. If you just want it for going to the range, or deer hunting or something, .308 Winchester will do the job.

    It's going to be easier to shoot because of the lower recoil. It will probably cost less too. And the accuracy and range are sufficient.

    On the other hand, .300 Win Mag goes where .308 Winchester can't. It has more power, more range, flatter trajectory but at the cost of higher recoil, higher price.

    Have you considered a .30-06 possibly?

    Had a Winchester mod. 70 300 win. magnum a while back. couldn't ask for a better shooter, power, speed, or accuracy. Does pack a punch, not a regular target shooter. Bottom line - if you want to take it down from 1000 + , get the mag. with a good Bushnell scope. Wish I had mine back!

    since you have the .338 lapua, the ballistic niche the .300 win mag would give you is already filled by a better round. Go with the .308 and have your mild long range paper driller...

    A human head will split open at 1000 with the .308, most .308s under 190 grains are still going to be supersonic at 1000, you will still have your kinetic shock and cavitation.

    The .300 mag will only cause you to flinch and miss the human head;)

    Get the 300.
    Cheap .308 ammo is available, but .308 ammo that will travel 1000 yds and still do damage will easily cost as much as the 300 win ammo. And the 300 is a faster, flatter shooting round. For your intended purpose, that's what I would go with.

    With a good scope the 300 is a tack driver at 1000. check the stats. 300 is the best power-speed-trajectory made
