Red Barron - I know you mentioned maybe looking for a Carcano… I believe, just a guess, that for accuracy - you should look at any of the models that are not arsenal cut down to make carbine models.... From what I have read they had "gain twist" barrels and when they were cut down it sometimes had dramatic effects. I have one like that. But, I may get better accuracy in this rifle if I use a lighter bullet than 139gr.... This makes finding the .268 bullet difficult.... there are plenty of choices under 139gr in .264 - but, if the bore is worn the .264's may not make the grade.... It is just a theory....
