Hi Adam....
My Volunteer can shoot 1" groups periodically and less than 1 1/2" groups at 100 yards consistently with a 470 grain gas check bullet and a 480 grain Lyman 457121.
My Green mountain barrels in 58 and 40 shoot touching at 50 yards. I've not shot them to 100 yards except at bowling pins, which the 58 plasters them regularly. These groups are from shooting off of two bag rests, a very accurate arrangement for sighting in.
My Whites all shoot accurately too, with my T-bolt doing better than an inch from time to time my last target was 5/8" for two shots. I knew when I was ahead.
The problem is Adam, I don't hunt off of a two bag rest. I can't shoot worth a darn beyond 20 to 25 yards offhand, and so have to be sitting for any shot beyond that. Normally my hunting ranges are usually quite close, my longest recently was a lasered 123 yards in a nice in velvet axis buck on Lanai
Of the neck shots I have taken, one was about 3 yards, several others maybe 7 to 10, the doe that started this thread was at the most maybe 12 or 13 yards.
What shots do I take mostly? I advocate the double lung as the most effective shot for any hunter and take them every chance I get, but there are other very effective shots with big bullets as well besides the double lung.
Have a Merry Christmas Adam and enjoy a prosperous new year!!!
Aloha...
