Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Lyman 45th edition 1970, page 62, has 140 grain jacketed bullets with IMR 4895 at starting 31 grains and max grains at 35. I have not used this powder its listed in the source. I use IMR 3031 in most military cartridges and with 140 grain jacketed bullets I use 32 grains, Lyman also lists this at starting 30 and max. grain at 33 for IMR 3031.

My book lists the starting charge for 4064 and a 140 gr. bullet as 32.0 grains.

I checked my book and 5 years ago I had good results with a lower grain bullet in my Arisaka carbines. I used 31.5-32 grains of IMR 3031 with a 129 grain Hornady GR SP Interlock bullet # 2620. It is a .264 bullet. Some have accuracy and tumbling problems with the 6.5 Arasaka ammo. You might want to slug the bore and see if it is around .264 or as high as .268?? I neck size the cases and each box is for a specific (fire formed case) fit for each rifle. Cases have a tendency to enlarge in some 6.5 Japanese rifles. I use RCBS shell holder #15. I use redding's neck sizer # 81224. Lee also makes a cheeper Full length size set for the Arisaka. But my chambers seem generous and the brass case expands like a .303 enfield cartridge. Another round that I neck size. Fire some factory ammo and see how much expansion your rifle cartridges experience. See if a Norma factory round tumbles or hits the target as a keyhole.

Please let us know how & what bullet works best and how IMR 4064 works for you. What is your brand & type of 139 grain bullet? What does the carbine slug at?
