How accurate are Japanese rifles?
Back when I had a convenient place to shoot longarms, I tried shooting my 6.5 Japanese rifles. I tried a Type 38 long rifle, carbine, and Carcano Type I with Norma factory ammo, all with mediocre to lousy results. As I recall the bores looked fine and I don't remember anything visibly wrong with the sights. Is this typical?
Not quite OT - just going a bit sideways
Carcano accuracy:
the problem with Carcanos is, that having got a super-cheap rifle, the owners want to shoot with super-cheap ammo - and get poor results.
The topic of loading for the Carcano has been covered on the Ammo & Reloading forum in some detail.
The acceptance criterion for the M91 (the Italians do NOT call it a Carcano) was a 6-shot group of MAX 5cm wide x 6 cm high AT 200 METERS!
That is 1 MOA quality.
See "Il Novantuno Mnnlicher Carcano", Wolfgang Riepe, ISBN 3-932077-30-X / ISBN 978-3-932077-30-2. Page 86.
And my M91/41, otherwise known as Roma, 'cos that's what it says on the butt, produced three 1-1/2 MOA groups at 100 meters (2 shot by me, one by a friend) as soon as I got the right bullets.
In general, every milsurp I have tried had, at best, a mediocre performance with off-the-shelf ammo and needed "personalized" ammo to get satisfactory results. The only exception to date was the Swiss G96/11, which performs superbly with the standard Swiss ordnance GP11 ammo, and is the only milsurp for which I do not have to reload.
I do not have an Arisaka, but have little doubt that the same applies - look around the forum and you will find some tips. Many milsurps do better with a flat-base bullet than with a boat-tail, because of a generously cut chamber plus a long/worn throat. And neck-sizing only is often advisable, both for accuracy and case life.
