reloading the 6.5x50mm jap Arisaka discussion 

Thank you again Sir. Watched all videos on 50/70. Well have an old Arisaka and looking to shoot. Pull up you tube and there you are. My trust in your knowledge is great. Thanks again.

Glad to see your still making videos 😊. I only have 15 rounds of 6.5x50mm left. Hard to get sometimes. But i do have over 600 rounds of 156 grain blank ammo from proxy bid. I shot off a few yesterday for the 4th lol. Didn't have ear protection, so my ears were ringing lol. (Edit) i have been looking into reloading myself, but i need to read up and study more before i do.

Flat base/Spitzer or boat tail I have discovered can play a hand no clue what/why have an old 30-06 with new loads prints 3-4 feet with the spitzers now with a flat base bullet pretty much same hole. Awesome video

I bought Norma at half price on sale, same cost as PPU brass. Hornady 11th edition and earlier books are INCORRECT on load data for 140 gr ELD bullets. They list the H4831 powder incorrectly. Max you can get is about 47 gr into the case before you end up packing in powder into pressure spike. The Case Overall Length are also TOO SHORT, causing rounds to move forward and back in the magazine as well as bullets jumping into the throat. Make sure the rounds are loaded to MAX COL only. I have the original Japanese rounds to compare with.

I had a small bench lathe and made 6.5 Japanese from new .303 British brass. Best to use Winchester because it is usually on the small side. I made a small tool to cut down the rim and deepen the extractor cut. I split a case and the internals are almost identical.

I can explain why Japanese ammo swells up when fired. Japanese armorers determined that automatic weapons with oversized chambers helps shell extraction, so they decide to carry that concept in manufacturing all their infantry weapons! I have Japanese rifles all of them have the oversized chamber, which limits the number of times you can safely reload Japanese ammo to like one or two reloads Max! However I found a trick that helps you maybe double that amount of times safely and that is the use of 1/4" masking tape. You take the masking tape and put one wrap just above the extraction groove. What this does is center the cartridge inside the chamber so as you fire it the expansion goes all the way around the case as opposed to just one side, which normally happens. One other thing I feel I need to point out is the type of rifling the Japanese infantry weapons have is called Medford rifling, the lands and grooves are rounded so there is no sharp edged rifling normal found in U.S. weapons, plus all bores are chrome lined which makes for very durable weapon.

Part of the reason the cases tend to bulge is that the original SAAMI specs for the cartridge were wrong, so companies all made dies and ammo that was smaller than it should be. The apparent reason for this is that when SAAMI first measured to produce their official specs for the round, they used a Japanese machinegun cartridge which the Japanese made slightly undersized for extra reliability in their machineguns. Combine that w/ a generous chamber and you get issues with bulged cases. Apparently Norma's newer ammo is made on the updated specs and should be better. But, chances are your sizing die is out of spec no matter what brand you're using. You'll also see incorrect case lengths throughout many reloading books from 1.984 to 2.008.

Good video

Hello good sir my grand father gave me one of these rifles and allways told me growing up about how well it shot I would love to find a few shells just to take a deer with it. If you could direct me in any direction of where I could buy some

Helllo TheKoba49, I liked your video . I reload 303 British for my lee Enfield’s/Ross and I have no issues . What works best for me is I fire form to chamber with factory ammo , then take the spent cases and neck size them with lee collet dies.

Graf's and son's usual has what I need. They always have PPU in stock. Still trying to copy G-11 Swiss tried several projectiles but setting depths and thight chamber been a issue :-)

Newbee question, if I switch my primer to Magnum primer, do I need to decrease my powder? Thank you!

People do claim different diameters for the 6.5 arisaka groove diameter. The italians did make some of their rifles "The Type I rifle Arisaka (イ式小銃 I-shiki shōjū) was produced during the early years of World War II for the Japanese Empire by the Kingdom of Italy (Type I is not a numeric symbol, it denominates Italian).[3][4]" en.wikipedia.org/wiki/Type_I_Rifle The Italian 6.5 was .268. Could some of the 6.5 arisakas have .268 groove diameters.

Is it cheaper to load 6.5 than it is to buy?

Ebay will more than likely have the dies

Could you make me around 20
