Are the .44-77 BN and the .44-90 BN viable contenders in modern Creedmoor

[beltfed]

Jim,
I have been looking to a possibility that I could put on a squadded practice at 600yds
at Wi Rapids in April before the Lodi match which is April 30/May 1.
It is tight, what with other things going on for me and my wife may be in cancer treatment.
Also, I did set up two dates for Rapids later in the summer. July 16 and August 6.
1818 and the 20th 21st Long range at Lodi. I will again have one gong and one
300/600/600 paper match
Hope you can put our matches to good use for tuning that 44/77
