6BR 13.5 twist and Zero Freebore Project

[urbanrifleman]

New Kreiger 13.5 twist barrel all chambered up (I polished it by hand by myself!!!). Going to be shooting 6BR with zero Freebore. LT32 powder and 70 grain bullets (70 TNT to start). Then I am hoping to get some Bart's to try.

I have CCI450s and 205 match primers. I wonder which one would be better?

Don't be afraid to try Berger's 65 grain column bullets.

 

[WyleWD]

Definitely try both. But based on my experience you'll probably like the 205s. I think you'll like that twist rate and the light bullets..... like the 65-68gr. WD

I am going to use the 205s with the LT32 to start. That seems to be the primer of choice with the short line shooters and the fast powders.

I was looking up 6br 13.5 twist stuff and this popped up.What ever happened to this project? This seemed like a winner..

@urbanrifleman
Any update on this. Curious as to how the LT-32 worked out.

The post is 5 years old. If I get a chance I'll try to dig out some data.

I love lt32. Would be excellent for any lighter bullets in 6br or 6bra. Perfect for 223 lighter bullets too.

Just no how thorough you are, and figured you had more information.

I've been on the phone all morning with customers I'll try to drag my book out when I get a chance.

Yeah that's it.

Interestingly enough I rechambered this 13.5 to 6 BR Ackley and I have a 12 twist Brux and I was going to sell the action and barrels here pretty soon
