Mark I ammo preference

[Gary Jordan]

do the Mark I rifles have a preference of ammo ?

Every rifle is slightly different, ammo that one likes may not be the best in another of the same model, year, etc. Generally, SV ammo does better in most guns tho semis may not cycle properly with SV. Also, the more spent on ammo helps accuracy, but some rifles may not respond as well as others even so. Best bet is to buy several brands and shoot a whole box in one session, keeping notes on performance. And clean well between brands as some have lubes that can affect other brands accuracy, cycling etc.
Have you 'searched' here and other forums for comparative info ??
