Lyman 310 6.5 jap questions

[mikeatl]

I bought a set of 6.5 Jap dies and it came with a #7 primer seating die. I have read that I need a #2 die. Will the #7 work? Also it came with a 137 N/S die. I have another 137 N/S die and there are differences in their length. One is 1.568 and the other is 1.426. Which one is better? Thanks Mike

The #7 is the priming chamber for 303 british etc. The #2 and #7 aren't interchangeable that I'm aware of. No help on the other question...

Thanks NoZombies, I knew with my luck they wouldn't be. I have a few extra items so I guess I can list them in the 310 Swapping thread.

Just to add to the confusion my 6.5 jap die is 1.612 long -
My die is an MR die and is marked 6.5jap not 137 -
your dies MR or CMR's

Dies numbered 137 were originally used for 6.5mm Mannlicher-Schoenauer, as early as 1927 (the earliest list I have) through 1955, after which dies were identified by caliber rather than by number. For a short while (1950-1951), No.137 was also used for the 6.5mm Japanese-.257, a wildcat popular for a few years following WWII when proper reloadable (non-Berdan primed) 6.5mm Japanese ammo was not readily available. Beginning about 1952 or '53, the number 137 was also used for the 6.5mm Japanese cartridge. As stated before, correct Priming Chamber for 6.5mm Japanese is No.2., the same as used for .30-06, .45 A.C.P., etc.
