some time ago I bought a type 38 arisaka that was a pacific bring-back. I found a box of hornady custom to run through it. It jad a propensity for bulging cases alsmost ad if it had been rechambered, but none of the dimensions worked for anything. so, being as it was all original and un-ground it got put up. Here recently I bought another type 38 to have one I could shoot. lo and behold it bulges cases just like the other one. A friend offered me a douglas match grade barrel blank for $50. the sporterized arisaka is getting it. I think I'll avoid 6.5 Jap... the other two choices that look good are 6.5-08 with an Ackley shoulder or 6.5x55 Swede. any thoughts?
