You can't go wrong with the PRS if weight isn't an issue. The extra weight may act as a counter balance for the 22" barrel.
Which is preferred depends on who you ask but I'd say that there are far more PRS's in use on the type of build you're doing. The PRS also comes with a bottom rail for mounting a monopod.
What you guys are saying/doing is what I took away from the video. As long as your groups are good there's no need to remove the copper, only the carbon. If you do remove all the copper you'll need to fire a few fouling shots to get it back right . I'm due to watch that video again, it's freaking awesome <thumbsup>
I was looking at this earlier http://www.scribd.com/doc/54709593/EPR-Briefing#fullscreen and was wondering what the actual performance was? Not the dog & pony show from the Army^^. What's the real scoop?
Funny, but they all should be made to take a conservative test before being allowed in.... It's a disease that will sooner or later be the end of Texas as we know it :-[
I have a new Black (AR-15) PRS stock for sale. I took it off my repr as soon as it arrived, it never left my house (Mint Condition) $180.00 shipping included. Paypal - gifted or USPS money order.
No, what I'm saying is both the 1-10" twist rate & the 1-11.25" are happy medians. They should do equally well with the most common weight 308 bullets (147 -175). If you knew that you would be using predominately light bullets say 120 to 150 you probably would be better off with a 1 -11.25" or 1 - 12" twist rate. Likewise if you planned to use predominately heavy bullets 175 - 220 you probably would be better off with a 1-10" twist rate.
Far more important than twist rate is finding the ammo that your barrel likes best.
Haystack, from your first post^^ If you plan to shoot 750+ yards as stated above the heaver bullets(165 -180 grain) will preform better at those distances. The 1 in 10" twist rate will stabilize the heaver bullets a little better than the 1 in 11.25" twist rate. That being said either twist rate will do the job with the typical 147-175 grain bullets.
You mentioned using mil-surplus ammo, you would not want to shoot hogs with FMJ bullets.If you're going to shoot long distance you pretty much have to stick with the same ammo or re sight in your rifle every time you change ammo as your point of impact will be way off.
Haystack, I hate to tell you this but there isn't any #1 barrel maker. You can buy two barrels with the exact same specifications, SN# 000001 and SN# 000002 from Whoevermanufacturing and #1 might shoot 3/4" MOA , #2 might do 3/8". If anyone tells you that Whoevermanufacturing is the absolute best & most accurate barrel they're full of crap! IMHO
The Obermeyer 5-R™ style rifling is simply a different style of rifling that has a more 'ramped', or angled transition from the groove to the land and back down from the land to the next groove. Our conventional 4 groove rifling has nearly parallel sides to the groove. The internet is full of information describing perceived benefits to the 5-R™ rifling over conventional styles, but most of this is comparing "apples to oranges" as they are usually comparing one manufacturer's "non 5-R™" to a different manufacturer's "5-R™" barrels. We have honestly seen no significant differences in accuracy or performance between the two styles of rifling when comparing our barrels.
Thank you, Krieger Barrels
