[QUOTE="1doug, post: 103580, member: 3863"] I would get with shawn and have him do it. he has the reamer on hand and can give you load data to get started . [ QUOTE ] so with the 338 whisper i would use the 308 bolt face.what parent case would i start with i was looking at cutting down the rem 7mm case how loud would it be with out a can? I know how i want the rifle built but still not sure on the round or where to get everything i need [/ QUOTE ] it would depend on which reamer your smith has. the 338 wisper is based on the 221 fireball as well as the 7mm br remington brass the only things you gain without a can and subsonic ammo is no sonic boom(crack)and no worry about transitioning thru the transonic zone. from [url="http://www.sskindustries.com/cartridges.htm"]http://www.sskindustries.com/cartridges.htm[/url] [ QUOTE ] One Whisper® series from 6 mm, 6.5 mm, 7mm, 300 and 338 is based on the 221 fireball case.
