I have an Arisaka ttype 38 that I got pretty cheap that was purported to be 257 Roberts, It was actually a 6.5X257 Roberts which I found out before I actually bought it and was able to low ball the offer to where I was happy about it. I got the proper dies and have shot the rifle some. It has a short barrel and so is noisy and the muzzle has been butchered and a home made front sight that is too short to be able to zero the rifle has been soldered on. I like 6.5 bore rifles. I would actually like to have this rebarreled into a 22 inch long 260 Remington and I would like to improve the trigger while I am at it. All the short chamber barrels I have seen are to fit Mausers, Is there a source for short chamber barrels that would fit an Arisaka? How would I tweak the existing trigger to make it less military?
