Playing with a Arisaka Type 30. 6.5x50
The bore is well worn, but still has rifling.
So far the Lyman 266469 seems to work the best, but i know it's to small.
My mold cast at 265 to 266 after powder coating.
I don't size it at all.
Gas check is seated by pushing the boolet, check first, up into a 266 NOE sizer, just to seat the check, then pushed down with a wood stick.
Works well
Is there a bigger 6.5 mold made????
I have a 270 mold, but I think it's to much to size down.
