Re: 375 caliber 350 grain Sierra's
Guys,
The 350gr 375dia projectile you are referring to is NOT available from Sierra. They were a "custom" batch made for Cheytac with Sierra unable to provide anyone with any information on them. To sierra it is like they did not even make them when you call them for any information.
IIRC the BC is somewhere between .82 to .9. Contact "Notaguru" and/or Steve123 via PM and ask him the information on them. I have not used them in my 375/408s and really do not plan too lol.
Thanks
