Bart's 65 and 68 grain flat base bullets

[norton850]

Free bore for Barts 65 and 68 grain flat base bullets ? 1 and 13 and 1/2 twist rate, 6 BR.

035" works great
045 too

I like no freebore in mine after my long freebore 6 BR's lands receded and I was seating so far out to stay into the lands that not much bullet left in the neck.

I use an .045 Freebore with 1.510 overall length with my 6PPCs. Works well with all my short range bullets!

1.510 OAL(?) Is this a typo? Just curious. WD

I think he's saying his chamber length on the reamer is 1.510

I believe he is talking about his brass' length.

Nope not a typo. It’s the overall length that a case can grow before it hits the end of the chamber. In my case 1.510. To determine the true length of your Freebore you need to know the overall length that your reamer cuts plus the Freebore.

Thanks, my bad one. I was stuck on the measurement including the bullet. WD
