Just sayin'.

Does 195 Berger and 175 barnes correctly stabilise in your .280 barrel or any factory barrel?

Berger rec.min 8.3" twist
Barnes rec.minimum 9" twist for 175 tsx and 8" twist for 168 LRX.

So to get all that superior 7mm bullet selection one needs a custom barrel.

From what I understand,180 Woodleigh will properly stabilise in 1:10 270cal
...
I didnt want a hyper pressure .280 AI to tickle the heels of the 7mmMag like some folks,
I wanted a round to achieve my target MVs with good relative margin of safety.


No problem with custom barrels, but I've never found a need for anything heavier than 162g in my 7mm RM. If/when I shoot the barrel out and replace it, a 1-8 twist isn't any more trouble than something else.

Trystan said .284" bullets were stuck in a rut when it comes to high BCs. Just pointing out some of the bullets that are out there that contradict his claim.

Personally, I'd rather have a good 6.5-06, standard or AI, than a .270. And do. My 6.506AI is Krieger barreled and 1-8 twisted.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.
