    I like the 20" on my savage but the hbar is too much for what i use it for. i have a trade pending for a 700 SPS w/ the 24" barrel

    has anyone had a rem 700 factory barrel cut down to about 16? or 16.5?

    biggest shots i'd probably ever want to make are 300yd.

    opinions? suggestions? am i retarded?

    At 300 yards, the velocity decrease via short barrel would probably be about dick.

    If that is your most common distance, I'd try finding a 223 and take advantage of the cheaper ammo.

    i already have a bunch of 308 :o

    by "the velocity decrease via short barrel would probably be about dick." do you mean that it will have fuckall worth of velocity? or that the velocity difference at that range between the 24" and 16" will be minimal?

    No, you will certainly likely lose velocity. Given that factory tubes are kinda slow to begin with, it would likely even be more noticeable in your case.

    Regardless, assuming you are running decent bullets, 300 yards just isn't that far. Dial up a little in ele, and watch the wind more.

    I've got a 20" LTR bolt rifle and a Saiga .308 with a 16" tube. everything I've read online says that around 20-21" is the optimum length for .308 when weighing portability and velocity. They say that with .308 out of a 20" tube I can expect 2700-2800 with Nato surplus. With 16" that drops to around 2300 or so. I've heard that for every 1 inch below 20" you lose about 100 fps.

    I don't own a chrony and haven't measured these stats at all. With a 16" .308 You're going to get A LOT of boom. If you're looking to cut down the 24" bbl. I wouldn't go any lower than 20"

    I don't shoot AR-10's but one of my squad mates does. He is one of the better guys shooting heavy metal class. I've heard him more than once denounce the 16" AR-10. He runs a 20" gun.

    Would I be better of cutting the 24 to 20" or selling the 24 and buying a 20? It's just going to be a casual hunting rifle and occisional target so I can't justify building the gun up but, at the same time, 24" is too much for what I will use it for.

    still not sure i want to trade. i may take it and my x51 battle packs to teh gun show this weekend.

    You guys forget he's shooting at 300yards......


    Buying/making better ammo will trump the velocity loss any day/all day.
