As you can see, someone else is thinking about a (FAST) cheytec. But right now my 6.5 Voodoo spitting 140 VLDs at 3475 into 1/3moa groups is keeping me satisfied, oh and did I mention it's mag fed

Your killin me! This is already hard on time and $$. Now you want me to paint flames on the bullets too!

No gain twist here. You experiment on barrels and let me know which one works.

Re: fastest barrel manufacturer

Ok did some more reading and seems you can't get 5C/R rifling and gain twist, yet. So I would just get a krieger or broughton 5R 36"+ then have a reamer cut with a 3/4 throat lead and absolute min spec. Then coating bullets with HBN is easy. I'd even split the reamer cost with you as I do plan on building one sometime...

Elkaholic,
Yes I've heard that too, but there isn't quite enough data to really make a factual claim (for me) and I haven't tried it so... Now, 3 grooves have also been rumored to last longer because the thicker lands take longer to wear down (I.e less of the land individually rubbing against the bullet, if that makes sense...)

Your welcome to use my reamer buddy! However it has been ordered and can't be changed now. Without giving you all the details(not because I want to hide them, but I don't have them) the man making the reamer assured me we're "on the ragged edge". With that said there could be issues. I'm gonna leave the bullet paintin to you! BTW do the flames painted on them really make them faster?

Yes, the 3 groovers do last longer IMO. My 300 RUM had 2500 rounds through it and still shot pretty well. Also, you CAN get gain twist and 5R from Bartlein. I had one ordered last year and then changed my mind on the gainer and just went with a straight 10 twist.It shoots lights out!....Rich

Re: fastest barrel manufacturer

Hi guys,

The 3 groove Lilja barrels, at least the one I have on my 270 AM is holding up very well after 900 or more rounds.

With Lilja's tighter bores I'd say this/these barrels are a bit slower than others.

I'm interested in the throat "thing" also. Kirby had a modified design but it seemed to wear a bit faster than "normal" in the extreme magnums.

Shawn has something interesting going with a throat design. Gaining 150 fps or so over whatever is standard in the Edge.

From have only 4 shots down the tube of a 375 AM with 350s at I suppose 3200+ I see no reason to want more speed. Travel time for the 350 - 375 bullet is pretty much identical as the 195 - 270 bullet at the same speed.

Its pretty impressive.

I'm figuring that if some one removed some trees a shot from Butler County to Westmoreland County would be doable. That's clear across Allegheny county.
