History of WWI Primer 033: Arisaka Type 38 and 44 Carbines Documentary 140gr 6.5mm @ 2500fps Seems like they didn't like it and bumped up to the 7.7. Kinda ironic since we're all about that type of round now days like 100 years later. Personally I think a 140gr jsp would have fixed their complaints. I bet a sks stretched out a few mms in the 6.5 might of been cool too. |

JSP would have been a no-go in any diameter.
Eta: What seemed logistically nightmarish was not only 2 different rifle rounds for 2 very similar looking rifles, but yet another MG ammo that fit neither. |

Which considering the height of your average IJA soldier, looks ridiculous. OTOH, rechambered to .257, and bubba'd down to like 20-22", it was a handy little rifle. With a completely worthless safety. |

They learned some stuff in Chyna and Manchuo-quo(Korea). It was "adequate", but I'd carry a T38 carbine in combat today and not feel terribly outgunned in caliber(and simplicity of the design, I own 6 of all 6.5 types including a original cavalry rifle). Today loaded ammo is very difficult to come by.

Seems like a number of countries fielding 6.5 rifles went bigger after using them in combat. I wonder why?

Apparently it was fairly popular to rechamber Type 38s to 6.5x.257 Roberts. My late father-in-law had one. After months of searching I finally found dies for it and we reloaded 50 rounds of 120 grain Nosler ballistic tips. Never shot it for groups or chronoed the rounds. Fun enough at the machine gun shoot.

Someone figured out you could simply run a .257 Roberts reamer through the chamber, and use readily available Roberts brass and a 6.5x257 set if dies. I have a really nice version in the safe... |

Can't remember if we loaded boattails in it or not. |

Quoted: Graf's usually has 6.5 Japanese brass in stock, and I think Bannerman's is offering loaded ammo for both. In a pinch, you can still format 7.7 brass from '06.

View Quote For GPMG use, you can pack more crap into a 7.7 sized package (tracer compound, penetrator) than 6.5. And they weren't hip to the yaw/fragment kill mechanism of good 5.56 (or 147 7.62 Nato, allegedly) yet. |

A different bullet and another 200-300 fps might have changed their mind. Also, what was the barrel twist in the Japanese rifle? Wonder if that might have made a difference?

View Quote View All Quotes View All Quotes Quoted: Quoted: Seems like a number of countries fielding 6.5 rifles went bigger after using them in combat. I wonder why? Yet 5.56 puts dicks in the dirt really well. I think the rate of fire of the 556 helps to compensate for that. I'm pretty decent with a bolt gun but I can put multiple 556 rounds in targets as fast as a bolt If stuck with a bolt gun I definitely wouldn't want a 556. I was perfectly content with my SAW. |

I have a non-last ditch 6.5 Arisaka that was given to me by my dad's best friend. His dad brought it home from the Phillippines, proceeded to cut the stock and used it as a deer rifle. The Mum is still intact.
The OEM parts are almost completely gone for these. I've been considering buying an airsoft clone to get the stock and hard steel pieces that you just can't find, like the dust cover and stock bands. It would just be a wall hanger and that's fine with me. When I was younger I shot 40 rounds of Norma through it. It actually shot pretty well and I was able to put all shots within a sheet of office paper at 100yd. Not bad for a crusty WWII bore. It did however push all of the primers out and I'm not so sure that the headspace is good. |

Thankfully they didn’t have access to the Hornady 123 gr SST or we would have needed a couple of more nukes.

The ammo today in that caliber is superior and in select fire. Crappy ammo was an issue. The doctrine of close combat and reliance of the bushido warrior spirit did not require a great rifle, just an adequate one with a long sword-like bayonet. Even as late as 1942 in Burma, they would charge en mass with bayonets fixed and an empty rifle. The Short-range weapons, like the light machine gun and grenade, were grudgingly accepted. The concept of a semi-automatic rifle like the M1 Garand was considered unwarrior-like. They were feared not because their weapons were superior, but due to their fierce adherence to their warrior code.

View Quote A country without a culture of riflemen may have made a difference too. Misses, slow shooting, slow reloading, and poor weapon maintenance may also have contributed slightly to Americans killing them faster than they killed us. |

While there were no doubt 6.5s in service the 99 in 7.7 was their service rifle in ww2. Prior to their desperate actions in ww2 I'm pretty sure accuracy and weapons maintenance weren't an issue anymore than any other country. |

Quoted: Quoted: Quoted: Several countries used 6.5mm cartridges. 6.5 Jap 6.5 Dutch 6.5 Mannlicher schnauer 6.5 Swede I'm sure there are others. 6.5 Carcano for one. From that list where did they go next? Japs went to 7.7mm. Dutch went to .30-06. Austrians became Germans, went to 7.92x57mm. Swedes went to 7.62x51mm. Italians went to 7.35mm briefly before going to back to 6.5mm for the duration of the war. Good argument for a high/low mix in machineguns/rifles like the Swedes did - 6.5x55 in rifles & LMG (improved BAR), 8x63mm in artillery carbines & medium/heavy(water-cooled) machineguns (staffed by artillery troops). We look to be doing similar: 5.56x45mm for carbines, 6.8 Super Duper for rifles & LMG. |

Ask a Marine on Guadalcanal, a soldier on the Philippines, an Aussie on New Guinea...6.5 was scary enough along with whatever else the Japs sent their way. Crom count the dead.

Get a good reloading book and you will find every bullet diameter has been tried.
The only thing that counts is can you consistently put the bullet in the target. |

The 6.5 Arisaka was an adequate round. In China it was found deficient, possibly due to lack of penetration through thick winter clothing. That wasn’t an issue in the south and southwest Pacific. The 7.7 Arisaka was a superior round but the Type 99 rifle it was chambered in didn’t make a real appearance until a few years into the war with the Allies. The Type 38 6.5mm served the entire war and in greater numbers until very late in the war.
Japanese ammunition suffered in velocity and reliability as the war went on due to the US bombing campaign and sinking of ships causing a reduction of imports of needed raw materials for the powder. |

View Quote View All Quotes View All Quotes Quoted: A different bullet and another 200-300 fps might have changed their mind. Also, what was the barrel twist in the Japanese rifle? Wonder if that might have made a difference? Bullets from that time period were often designed for maximum penetration and terminal ballistics suffered as a result. A different bullet design that tumbled rapidly would have been more effective (and bad news for US). Twist rate makes no difference to terminal ballistics. Quoted: What bullet would have been more effective but would also have been available to them? More pointed shape with the center of gravity moved back in the bullet to get rapid tumbling. |

After the era of big long hunks of lead piercing the air at 1500 fps up to 1800 with 350 plus grains of lead anything was an improvement. Even the 1903-03 Springfield fielded a 220 2300fps slug that crashed through everything it could reach. Just look at the progression of the U.S. from 45/70 to 30-06.
At the turn of the century pointy fast was what everyone was after. Slow crushing lead was left to the annals of history. The problem with the jap 6.5 was they didn't have enough of it, period. Send troops with 5 cartridges and inflict what damage they could. And they were not the only army that used that tactic. They were not getting a resupply why wither their combat strength waiting for something that was not even going to land on a beach. The canal they lost thousands to their combat tactic of rushing forward hoping to overwhelm the U.S. forward positions. And what did they do, the japs loaded up and went to Rabaul. Nothing wrong with the 6.5 during WWII just could not get any. |

I thought I heard they made the switch for better tracer performance?
