Does anyone know the the effective range of a 123grn pill out of an 18" Arisaka?
I am not to sure about the exact loading data but can get it. Thanks in advance.

I might, but there is another bun in the oven so I have to change it to a new one. That picture really seems to bother people.

First off we need to consider what it is that's being asked.
http://gunwiki.net/Gunwiki/FactorsOfEffectiveRange

Then there are a lot of variables to factor in. For example the cartidge is a lot like a Mauser which is effective over 1000 m. However the bullet is much lighter than a 8pm Mauser bullet so it drop energy quicker. Also an 18" barrel doesnt allow as must gain in velocity as a longer typical Mauser rifle. With lots of hand waving and very little real information I'd figure about 500m - 800m. With a longer barrel it should be able to out range the target rifles shooting 223.

Thanks for the educated guess.

You'll get better results with a bullet in the 140grn range. Loading data from the 6.5x57 can be used. But be aware that's a European cartridge, and they load hotter.

yeah, go a little heavier, but with a short barrel you're not gonna be real effective beyond 500. 6.5/257 is a decent hybrid but quite frankly you can load the hell out of 6.5jap without much trouble. a historic test was a a rechambered arisaka in 30-06 that they never rebarelled. they were firing 30-06 through a 6.5 barrel and couldn't blow it up!

Your avatar is just fine Baxter. I've been in love since the bayonet group buy.

I believe it finally shot the barrel out of the receiver. The threads were undamaged on the receiver so it could of been re-barreled again.

couldn't remember the final result, but the 30 cal through the 6.5 barrel sticks in my head. good stuff.

barrels blown, minds blown, T-38 actions for the most part remained intact

I have a 6.5 Arisaka Type 44 that my grandfather brought back and that thing is horribly inaccurate out to 100 yards.

Beyond that it is probably not too bad. My book shows loads for the 140gn boat tail bullet.

there were many reports that due to the load of the ammo and the length of the barrel, the T38 (and by extension, the Type 97) rifles were extremely effective in concealed fire because of the low smoke and muzzle flash. This was extremely bad for allied forces as it was incredibly difficult to counter-snipe.

I have a T38 Carbine (same as 44, minus bayonet) and it works great to about 150 (atleast to the end of my vision clarity). Course, consider that the weapon was designed to be used on horse mounted cavalry, it's a very antiquated military strategy, even in WW2 standards. With all the hopping and bouncing around, the rider was probably more likely to chase someone down with a saber and pistol, and not going to take pot shots at someone out in the far far distance.

i've got a 38 carbine as well and it seems alright to 100-150 yds. haven't had a chance to punch paper or shoot at anything further out yet with it but it shoot minute-of-crap in the desert, lol. we usually only have about 200yds or so to work with so i'm just guesstimating. haven't reloaded any for it yet either but i will be soon. i'd like to get a type 44, not really different, but different, ya know? i want one of everything damn it, maybe 2...
