    Cut it at 20, 18-19 if you really want it short, but 20 should give you better velocity and get you to 1k faster. Like Deadly said though, wind'll be a bitch at that range. especially if you aren't shooting the heavies, 69+.

    The other HUGE problem you'll have with a .223 PSS is which barrel it has. They switched from a 1:12 twist to a 1:9 twist (don't recall exactly when), but with a 1:12 twist running lighter bullets that will properly stabilize from a shorter, slower barrel...you are asking a WHOLE LOT to get to 1k.

    Plus, with the 1:9, you may not be able to stabilize heavier than 68-69gr bullets which is another mark against the rifle for getting out to 1k. Even if you have been able to stabilize heavier 75gr bullets thus far (which are better suited for extended ranges...along with the 80-90gr pills), shortening your barrel, losing MV, you may not be able to continue stabilizing them.

    Anyway, like folks have already said, 20" would be the minimum I'd want to cut it down to.

    I have a .223 PSS 1/9 cut to 20". I hand load the 69's with 24g of Varget for it and I have only taken it out to about 600. I was getting a chrono MV of +/- 2700fps. Try that number in a ballistics program and see what you get for a 1000.

    Let us know your results.

    Re: Minumum barre length to get to 1000 with a .223

    With those very basic numbers (69gr SMK, 2700fps) and without knowing your environmental specs (incl wind)...you get sub-sonic at around 730yds (give or take) and you'll need around 50+ MOA to get dialed in at 1k.

    Again...that isn't all that specific in terms of the data, but should be a hell of a lot of fun trying it (especially trying to dope for the wind).

    BTW George...great looking rifle!

    didnt mess with the settings that are on my bulletflight, but the 223 listed for 69gr on it changing the vel to 2700=52.7MOA 90f 768ft ASL

    The national match guys use the 75 & 80 gr pills to get to 1k. That is in a AR platform and the 80's are loaded one at a time. They are also a standard lenght barrels for AR, with the right pills the right platform, and the right shooter, yes you can play at 1K

    You might try the Berger 75gr. VLD. I know some guys that use it with good results at 1K. Your barrel twist may be a major problem with that caliber/distance combination.

    I got to 1000 with an AR15 (iron sights), 20 inch Krieger barrel, 1/7.7 twist, 80 grain Berger VLDs going about 2750-2800 fps (don't ask for my load). This was obviously for service rifle type competition. To get a .223 to 1000 you will need a fast twist (1/6.5-1/8; which I don't think Remington offers in a factory barrel), a high BC bullet, and a case full of powder...

    Since you have a 1/9" bbl...you can't use MOST 75 grain vld type bullets and definately not the 80's and 90's. That said...you will have a hard time @ 1000 yards even with a 26" bbl, so cutting it down will pretty much stop you from getting any decennt results at 1k. The service rifles with 20" bbls have 1/6.5" for 9o gr bullets and either a 1/7 or 1/8 for long 75's and 80's and even then it's no picnic shooting at 1k with a 20" bbl. I know of a couple guys shooting 223 AI bolt guns with 30" bbls with a 1/6.5 or 1/7 twist and 90 gr bullets with preety decent results @ 1k.
