Most precise (and durable) ligthtweight Faxon barrel for recommendation

[Londerko]

28.2 gr of IMR8208 with a hornady 123 ELD-M. OAL of 2.26”. CCI 450 primer and hornady brass
Haven’t shot it over a chrono yet, but it’s probably knocking on the door of 2500fps with my 18”
PS 28.5 shot almost as good, actually 4 of 5 were under .5” but that 1 flyer made it an inch.
I may try that one again to see if it was me or the load lol
