My son in law sent me a link to an article about the new Flat Line bullets produced by Warner Tool Co. with ridiculously high BC's. Seems like they are just now hitting the competition lines and I'm curious to see how they do.
Since they are turned and extremely long for caliber, I'm curious what twist rates are working for the competition shooters and others who are getting first shot at these new miracle bullets...

Found the link I lost earlier.

I have some 30 cal 200 grain bullets coming any day. My rifle build for it is on this forum. Problem with a Remington LA mag action is the 4.250" length of a loaded round. It will have to be shot as a single shot. I am building a 300RUM. I have a bud that hunts hogs off a bench that is 1000 yards from his feeder. I'm waiting on the bolt in order to chamber it. Alan sent samples so that I can throat the rifle properly.
I should have said shoots hogs, not hunt hogs.

Butch,
Since these bullets are so long for caliber, what twist have you settled on?
I'd be curious to see what the ballistics work out to with the 200 grain 30 cal bullets.

Alan recommended 8 twist. That is what I have in my lathe waiting on the bolt.

Did some tests with the 155.5gr 308's, and have the other half of them being Pressure tested by another member right now.
A 10 twist will happily stabilize them. The Pressure Trace will provide the coffin nail, but in my rifle: same jump to lands with the same charge of CFE, velocities are identical to the 150 SMK loads.

Haven't shot in great enough weather to see ultra long range groups, but by the tail angle and CG/CP I highly doubt they'll cross trans-sonic.
I do hope Mr. Warner sells enough to stay around, very nice gentleman.
