RIFLING TYPE

[texas]

Dave thanks for the info, I'll give Jim a call. What I think I want is to neck up a 308 case to take a 338 bullet.
If they can do it with a 35 caliber bullet (358 win.) then a 338/308 should work. The 358is suppose to get about 2200 fps with a 300gr. bullet and 2250 with a 250gr factory load. I hope to get at least 2500fps out of a 22-24" barrel with this combination.
