Hi All, Thank you for your responses. I have been in touch with Ron Reed, and looks like I'll be in good shape.
FYI, I have talked with the folks at DakotaArms/Corbon and they told me that the 300 Whisper (300-221) is not going to be available from them until they can locate a manufacturer to replace their former source, who has dedicated its line to producing .223 for the war effort. They have agreed to keep my order "on backorder" until the find a source.
Regarding CNC, they will only ship to a FFL here in New York State. Not really sure why they have taken this stand, as there are no restrictions on shipping ammo to upstate NY, New York City yes, but not upstate.
Ron, if you're reading this, Thank You for your support! I am looking forward to receiving my order and shooting my new barrel.
Gary0529 - Yes, the TC barrel is a 1:10. I have researched this cartridge, as best I can, on the internet, and above 200 grs. this barrel may not stabilize the bullets. As my interest is hunting whitetails, I hoping the 150 gr. Ballistic Tips will do the job. Ron has agreed to load up some rounds for me, so I'll know shortly. I'll also give the website you've posted a try. Thank You.
Does anyone have any experience with the available dies for the (300-221) currently on the market? With Ron's brass, will I have to "Full Length" resize, or can I just "Neck Size"?
Thank You Again, I really appreciate all of your inputs. Joe
