Hey all, got my Type 30 up and ready to shoot, my rifle has a rear sight that was not updated for the 139g Spitzer round adopted in 1907. Is load data for the typical 6.5x50 round made for the Type 38 safe in the older Type 30? Does anyone have approximate load data for the pre 1907 6.5x55 load? The 160g bullet at 2200fps?
As long as the rifle checks out, you can shoot either cartridge. When the 6.5 cartridge was updated for the Type 30, the rear sight was changed, that’s it.
I do not have original 6.5 load data but I was able to score a few hundred original 6.5 projectiles that were pulled and like you, I would like to work up a load for and shoot my Type 30.
Good luck and post results if you get to it before I do. [emoji1303][emoji1303]
Getting a T-30 to shoot well with modern bullets can be a pain . Slug your bore , you will probably find it to have about a .270 + groove dia . That will not even try to shoot a boat tail bullet well . The first bullet I would try would be the Hornady .264 160 rn with a medium load of fast burning powder listed in a manual for the Type-38 . That may work ok . To get real accuracy out of all mine I had to go to the old Hornady .268 Carcano bullet , but that is not for a beginner . PPU also make some .266 / 7 bullets that do not come with some of the problems found with the big Hornady bullet . You will loose velocity and pressure with the .264 bullet , so you may have to slowly up your load .
I appriciate the responses guys. Good to hear the only real difference was a updated rear sight, I am quite experienced with reloading for a plethora of old military rifle cartridges so luckily I am comfortable working with over sized bores and such. All my surplus 6.5 guns save for my M96 mauser are quite large to where privi and hornady .268 projectiles are too undersized, I size down 270 bullets to bore diameter on those guns, the type 30 of mine being no different, slugging out to .274
You do not need exact groove dia to shoot well . The long .268 bullet will bore ride just fine . I have shot 1.5 inch 5-shot 100 yard groups in a match with my very early T-38 with a .272 groove using those bullets . Unlike in Carcanos , those bullets seem to do just fine in early 6.5mm Arisakas . I never have shot very well with sized down deformed bullets .
With my ventures in reloading for these old rifles I have found the opposit to be true, bore to bullet fitment is key to at least military acceptable accuracy except for some quite specific chamberings, I have had good results with sizing down jacketed bullets, they aren't deformed when sized, same how cast are not deformed, and I size a Lot of cast bullets
All of the older military rifles worked with bore riding . Well you have found the opposite of the load testing of over 4000 military rifles by us , 15 years of military match results , custom bullet making for bench rest rifles . You are shooting sub 1 inch 5 shot groups at 100 yards on demand with smashed jacketed bullets ? We had found that makes for about 5 inch groups , which is about 500 % worse . Well good luck getting 1.5 inch groups with the T-30 and .277 bullets .
Sir you have no idea who I am, what my experiences and capabilities are, I suggest not assuming. I came here for simple advice which J-ROD kindly gave, not for someone to assume I am a beginner and flaunt their achievements. Perhaps I was wrong for using this forum.
Howdy fellas, I think maybe there has been a misunderstanding here. Folks please keep on track and civil with each other.
Thank you and carry on!
