6 mm ackley

[lead lobber]

Chuckster,

I think that is gonna be my next trick too! /ubbthreads/images/graemlins/confused.gif I thought this was gonna be my long range killa!! Now it is a continual source of frustration. /ubbthreads/images/graemlins/mad.gif Love my plane jane 308!!!

Load at the range. Select your brass from the cases that go into the group. keep the rest for sighters. I stay with Laupa .308 WIN and make all my cases from this brass. It's a pain I know. It's a shame we can't just buy better brass.

What are the steps to forming 6mmAI brass from 308? Is it more uniform? I thought one the case was fire formed it fit the chamber and it was ok. Guess not, would the 1-8 twist in my barrel cause it to throw fliers with the light wt bullets? /ubbthreads/images/graemlins/confused.gif

web page anglefire Try this link they use the 7x57 Norma brass and gives you a blow by blow account. /ubbthreads/images/graemlins/tongue.gif

[/ QUOTE ] I don't know what you mean by a light bullet? The one in eight twist would work with the vary longest bullets in this bore size @ the velo you get with this chambering. However if you are shooting benchrest length bullets in the one in eight......... /ubbthreads/images/graemlins/blush.gif

3-6bits,
Thanks for all the great info. I hope i can get this thing sorted out before i rechamber it. I spent alot on the the dies,seaters,brass,and bullets to stop now. But All my other ackleys have been so $&^%* accurate and easy. /ubbthreads/images/graemlins/mad.gif I bought a clymer gauge for 6mm ackley 40 degree, and when I chamber the gauge it is so tight I barely can get the bolt closed. Is this too tight? I know there is supposed to be a crush fit, but this seems a bit much. I lube my lugs good and take out the firing pin and ejector. I do all my own smithing and I have wondered if this could be a problem. /ubbthreads/images/graemlins/confused.gif /ubbthreads/images/graemlins/confused.gif Any thoughts?

My gun shoots 68Gr Barts and 75 gr Vmaxes into one large hole...sometimes /ubbthreads/images/graemlins/frown.gif I was asking if the fast twist (overstabalizing the bullet) would cause the intermuittant flyer? Again, how do yoou form the brass from 308 ??
Thanks

Chuckster ,
I think you form the brass from Norma 7 x 57 .
.308 is considerably shorter than 6mm Rem I think you'll find .
Do a Google search on 6mm Ackley . There's an article there somewhere on the procedure .

 

[Chuckster]

I form mine from 6mm Rem brass, but 3sixbits said he formed it from 308??Thats why my question how. Is 7x57 brass better to use than 6mm??

 

[Aussie]

Believe that Norma make brass for the 7 x 57 which is supposed to be better than 6mm Remington brass . Think I would just do some case prep. on Rem. brass and (if you're keen )sort by weight . Quite a few coming to the conclusion that neck thickness / tension is the major factor in prepping brass and that a lot of the other procedures don't make a noticeable difference unless you're shooting a 6PPC in benchrest competition . Their story , not mine . I don't have an opinion .

Hey Lead lobber Hey use Lapua Brass its great.How do you get it? well that's a small problem just re-chamber your rifle to 6x284,and purchase 6.5x284 and the speed of light is yours. /ubbthreads/images/graemlins/grin.gif

3sixbits,
How do you get your Lapua 308 brass to grow 6mm when you form it to 6mm AI?

iron worker,
ever heard of necking down norma 7x57? I hear two things....works great and......makes even more crooked brass /ubbthreads/images/graemlins/crazy.gif /ubbthreads/images/graemlins/crazy.gif /ubbthreads/images/graemlins/crazy.gif any opinions

Any body interested in a Redding micrometer bushing neck die,body die,inline micrometer seating die for 6mm ackley and I will throw in about 200 brass (after my PD hunt in May).
