Hi everyone,
<span style="font-size: 8pt">Let me start off by stating that I hope this is posted in the right section and that I have indeed searched the forum for answers to my question(s). My apologies if I missed on any of both counts. But now we've gotten that out of the way: </span>
I've got a fairly deviant plan brewing in my mind and require your assistance & advice. I want to take a <span style="font-weight: bold">AICS 2.0</span> left handed folding stock, a lefty <span style="font-weight: bold">Remington 700 action</span> and a <span style="font-weight: bold">chopped Lothar Walther bull barrel</span> and turn it into an extremely small but accurate short range package. By short range, I'm talking mostly <span style="font-weight: bold">50 to 300 meter range</span>. And by chopping up a Lothar Walther, I mean going below 16".
The idea is to chop off the barrel as far as I can, while still capable of using non-barrelburning commercially readily available ammo. For this, I was thinking along the lines of .223Rem (but I'd more than welcome alternatives). A short barreled .223Rem would be loud and bright, but reasonably accurate still. When imagining this build the barrel only sticks out a little bit past the AICS stock, about as far as a front folded Harris bipod would stick out (give or take).
As a sidenote: could someone provide me with exact length of the entire AICS 2.0 stock with the butt folded, as well as the exact length of the barrel up to the end of the short action stock? My guess would be 11" or so? Is this about correct? (the barrel would be longer than that, but it's a good reference point to start from for calculations of how long the barrel will actually be.)
My only concern with the barrel is <span style="font-weight: bold">accuracy & bullet stability</span>. Not stopping power, fragmentation, unefficiently burnt powder and so on, those things really don't matter. This rifle would be meant to kill paper, and nothing else.
I've got a Sig 551 SB that shoots quite well out of his 14.3" barrel (55, 62 & 63gr @ 1:10), I'd expect a bolt action with an extra stiff bull barrel to do quite a bit better still. Even going down to 13 inches doesn't do horrendous things to the group it would seem: http://www.accuratereloading.com/223sb.html
I would suspect that an equal quality .308Win wouldn't fare as well once past 16", or would I be wrong in that assumption?
If I'd aim to use .223Rem, which <span style="font-weight: bold">twist </span>should I go for if I plan on using 50 to 75 gr bullets (most likely using mostly <span style="font-weight: bold">55 & 62gr</span>)? 1:9? 1:8?
Any random thoughts, comments and further information would be a great help to me at this stage. Thanks!
