Also what brass are you using
I was wondering if Lapua 308 necked down would have any problems as it is heaps cheaper and more available than 260
Regarding the Lapua 308 necked down to 260:
I've never tried it in a 260, but I did order 100 a year or two for my two Tikka 7-08s. To be usable, it had to be outside neck-turned. It was REALLY tight if I didn't.
Right after I ordered the 308, I noticed Lapua was making 7-08 specific brass. I wish I would have seen that first. I have a nice Sinclair neck turning tool that just sits in a drawer now....
If it were me, I'd just get the 260 brass and not worry about it.
