chamber conversion 6.5 Arisaka to 6.5 Swede
In looking at the SAMMI dimensions for the 6.5 X 55 Swede, they list the inside neck dimension as .263 minus -.0028 or plus +.0008, so in essence a max inside neck diameter of .2638 ... and I always thought it was .264, but I guess that's close enough, or is it?
I was using the cartridge/chamber conversion tool on AmmoGuide, and I was surprised to find they did not include the 6.5 X 55 Swede as a do-able conversion for the 6.5 Arisaka.
I have an old Arisaka with a burnt barrel, but acquired a newer 6.5 Arisaka barrel in good shape, cut to 17.75 " with a target crown on it. Always considered doing the ream to Swede as I already own 600 empty brass, dies, and lots of powder and ball for the Swede round.
Now, I'm wondering if the AmmoGuide folks are just a little too exact, or if they are correct in telling me that I should not consider this conversion.
I still think it would work, but might have to turn the inside necks of the 6.5 Swede brass just a smidge ... maybe not. Any cartridge aficionados out there that could set me straight? Do I really need to worry about .0002?
