What are the advantages & disadvantages of a carbon wrapped barrel vs. a high quality stainless barrel? Ignorance may be bliss, but not when you are spending hard earned cash! Sonny <munch>

jgun, A 0.338 is usually used for large dangerous animals in North America or long range precision shooting. I would be willing to bet that with a laser centered boring machine this could be done. But, if you have eroded the throat on the barrel, you have also probably introduced stresses in the rest of the barrel. It would make a good practice or hunting barrel, but I don't think it would ever be a match grade barrel like Krieger or Shillen makes from a virgin blank. Once metal becomes heated and cooled it warps like wood, but to a far lesser degree, it becomes hardened and brittle. If it is made with extremely high quality metal with an eye towards reboring the barrel, (Like a commercial diesal engine block.) then I have no doubt that this could be done, especially since you are hopefully removing the surface case hardening in the bore before cutting new rifleing. (My opnion not based in metalurgical study.) Sonny <munch>

Boys, Don't forget that a lot of these magnum rounds are belted cases which may cause feeding problems, and what about the higher gas pressures? Will it fit in the magazine? As far as using a good barrel that has experienced throat erosion and jumping to a larger caliber, maybe. Don't forget about having to bore out the barrel and recut the rifleing. Someone like Krieger may consider reworking one of THEIR barrels, but they may just blow you off for liability reasons. I am looking through my reloading books and I still haven't found the specs on the .338 federal. Sonny <munch>

I don't mean to hijack the thread, but I too also want to build an outrageous 308 AR. If any of you know of a book, articles or videos, (I must go back and look at the Brownell's video) that will help with the consideration of parts for purpose, I would be gratefull. I noticed that SI Defense has a complete gas piston AR-15 utilizing Primary Weapons System, (PWS) technology. I have emailed them to ask about any developments in gas piston adaptations for the AR-10. I know that the AR-15/10 can be extremely accurate out to 600-800 yds. I just need to get it right the first go round. Money is tight and less than stellar, (ISO 9001) parts are unacceptable and undesirable. I need your help with this guys, no laughing icons accepted! LOL? Sonny

Having cleaned and shot the M-16 many times as an ROTC cadet in college, I would like to build an exceptional AR-10 in 308. However, this grasshopper lacks the wisdom when it comes to the ins & outs of just about everything when it comes to parts selection & the finer points of assembly. I want to use an SI Defense matched receiver set in fail zero with a Timney 3LB trigger, beyond that I have a lot of questions as to the finer points of this rifle. I do want to build a RIFLE that will outshoot me. I will be using my AR for target shooting and occasionally for hunting & varminting. I could buy a complete rifle, but I want my fingers to touch every part on this rifle. Can you recommend books, videos and of course you personal opinions? Thanks Much & God Bless Sonny
