I'm just running 260 Laupa brass through a 6.5SLR bushing die. it works fine. the factory brass has a thick neck wall and the fired brass has zero neck clearance. Not good for accuracy, you will have to turn if you have the same reamer dimensions.
I would try fire forming with lighter bullets if you have a zero clearance necks.
Are you running the standard neck clearance? I really want to use Lapua (especially palma) brass and don't mind the neck turing. Only thing stopping me from taking the plunge is i keep hearing everyone say "avoid anything that isn't American domestic"
Just turn the blue brass and give it a nice deep cut into the shoulder, i went through the Win brass thing with my 6SLR and had to do the same with my tight chamber and after doing it decided id rather do the same work with lapua, the Win brass never got me excited. I turn the necks into the shoulder, FF the brass to get that thick part out into the cut in the shoulder, give the necks another turn on the second load and make sure to cut into shoulderand than load from there. Most off my friends are doing the same with Palma brass to make 6.5Creed brass, you can also really size the neck down esp if you have Whidden Bushing dies that sizes the entire neck down, expand with a mandrel thats just a little bigger to get all that brass on the outside, turn the neck into the shoulder and than do your normal thing.
That's exactly what my thinking was. I'd rather turn necks - if for nothing else consistency of neck tension. If I'm going to do it a why not do it with Lapua. After your second turn how often do you have to neck turn to keep on top of the flowing brass? Donuts in particular...
With this new lapua batch Im only on my 2nd load now buy a buddy that uses everything from Nosler to Norma said he gives them a cut evey 3 loads and his not having any problems. Another friend said he did 5loads on his Lapua brass before he "had" to turn again but he has a no-turn chamber, with mine Ill also check/turn every 3 loads just to make sure and avoid any funny stuff.
Mike. What do you end up for case length after sizing the .260 Lapua brass thru the 6 slr die. Is your die a Whiddon?

Once fired 6.5 SLR brass formed from 260 Lapua came out about 2.945", you could not push a bullet into a fired case.
The formed 6.5 SLR brass was about 0.015" at the mouth and 0.0165" at the neck. I have turned to 0.014". Loaded rounds measure 0.293" so it should be good. Have not second fired yet. If you want to form from 308 brass you may have a lot of work, or get a big neck reamer. I have never done it.
What is the fireformed H2O weight on lapua brass for 6.5 SLR? I was using Winchester before.
Thanks
