Long time Swift shooter here. IMR 4064 and H-414 used to be all I used but on the advice of some folks at BR Central I went to AA2700 a couple of years ago.
Took very little load work and shot about a .180 with a 55 gr. Nosler through
my old Shilen barrel. Some guy mention the difference in barrel wear between
4064 and 2700 is like night and day but you can't prove it by me as I have no
borescope. Also regarding the Hornady 53 gr. V-max, I have found in my .22 BR
they will not handle as much powder as the various 55's. but are very accurate.
I believe the default twist in the various factory .22's would be better at 1X12
instead of 1X14.
