Fat 6mm Bullets

[Jerry S]

Got my first 6ppc a few days ago and ordered some ‘custom’ bullets to go with it. After fire forming with some cheap Sierra bullets I got out these expensive bullets and started measuring and weighing. Measurements were very consistent however these things are fat. .2446 give or take a tenth. All other 6mm bullets i have are between .2430 and .2436. Lapua are the skinniest at .2430 and all others including Berger, Hornady, Sierra, Nosler, and Barnes are all close to .2435.
Is this normal? Are they good to go?

Might want to check that your freebore diameter is large enough..not sure bout PPC but .2446 seems large... I have a .244” diameter fb in my BRA and that’s about as big as most go for VLD bullets.

Great suggestion. I am having some resistance on bolt closure. This may be due to my OAL being .020 into the lands though.

 

[Jerry S]

I should have stated that my measurements are at the pressure ring.

 

[Jerry S]

Above the pressure ring they drop back to .2440 then to .2437 a little further up.

Nothin wrong with a fattie

Some barrels really like the chubbies!

 

[Tim Singleton]

Just watch your loaded round neck diameter
I try for .0025 neck clearance with the ppc

 

[Jerry S]

Yep, I’m at .0014 with these. A little less than i wanted.

Yea that may be a problem. I shoot every shot over a Labrador for the last year
That tight I have seen as much as 100 FPS spread lots of 4 and 1 groups

Oh, the poor Labrador! Does he wear hearing protection?
