SxS-boy30 cal Bartlein Barrel
I have a few quesions about these barrels. Has anyone used them and are they worth the $$$? Will a 11-1/4" twist stabelize the 190,200 and 220gr Sierra MK's? I was looking for a Krieger with a1-10" but they're wait time is out to a five months now. Would you suggest anything else of equol or better preformance?
Thanks for the help, Joe

RamsgateBartlein's website says 6 to 8 months delivery time. Does someone have one in stock for sale?

SxS-boyRamsgate,
Look up grizzly.com. The have over 20 listed in 6MM, 6.5MM, 7MM, 308 and 338. mostly target contours but supposedly all in stock. The say that they order a few hundred at a time so there isn't a wait. The closest on eot you is in Muncy Penn. USA. Export might be tricky for you though.
Good Luck, Joe

DougH9I had them put a 12 twist on a long range 300 Win sporter for me and it shoots perfect with 180 grain B.T.'s. Very happy with their quality...fully equal to a Krieger (I have a couple of those also) in my opinion.
I would be confident with the 11 twist and the 200 MK, but the 220 MK might be pushing it.

I have the Bartlein 1/11.25 5r on a 30-06 and Kreiger 1/11.25 5r on 300WSM and used Broughton 1/12 5c twist on another 300WSM and used 1/11 twist Lilja on a 30-338mag and 1/12 twist on another 30-338mag.
I've shot 200gr bullet in the 1/12 twist 30-338mag and 180gr in the Bartlein/Kreiger/Broughton barrels never tried anything heavier.
Mike Rock (Rock Creek barrels) makes a nice 5r barrel have one of his on 270Wby.
I like the 5r barrels and the Broughton barrel pretty nice also. I don't mind waiting on a good barrel.

7mmfreakWith the 210gr Berger an 1-11" gets you about 1.4 using the Miller formula. I shoot 1-10" in .300WM.

Obermeyer, Krieger, Bartlein, Rock, all make fine bbls. Do yourself a favor and buy a Brux if you want another fine bbl in shorter time. I'd go 10 T.

SxS-boyThanks for the input.
7mm freak, what's the miller for formula? It sounds like something I want to know.
Thanks, Joe

IdahoCTDKrieger has a in stock inventory list and several of them have barrels in stock if you call and ask. bugholes.com has a ton of barrels in stock as does Bruno Shooter Supply.
I have two Bartlein barrel chambered in .243 AI and .30-8mm Rem Mag. I also have a 6.5 Blank. All of them are 5R rifling and the two I have chambered shoot in the .2" to .3" range at 100yds. With the best group out of the .30-8mm being .96" @ 550yds. That's less than 1". I wouldn't hesitate to use another but I'd use a Krieger, Obermeyer or Broughton in a heartbeat too.

7mmfreakThe Miller Formula assigns a stability factor to a bullet. Your goal is to be above 1.4 at the muzzle.
Easiest way to calculate is to use JBM Ballistics.
http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgiIt gives a better prediction than Greenhill in high velocity cartridges.

SxS-boyHey Thanks 7mmfreak, this is very interesting and I'm definately going to use it on future gun builds.
