Subcaliber Adaptors.

[gregwhite]

I am considering getting a subcaliber adaptor made for my Remington 300 ultra mag. I want something to drop in to take a nanny for meat while Hunting Himilayan thar. Something quiet. I was wondering would the 300 wisper be appropriate. I am a little worried that the chamber pressures might be a bit much for an adaptor. Anyone have any experience here.

I have mates that shoot 7.62 by 39's out of their 378/300's but I thnk the cases will be too large a diameter for the 300 ultra.

I have considered the 32/20 and the 30 US carbine... but they are a bit whimpy!!
