RDFIRENUT: Good for you on the great shooting Shilen Rifle in 222 Remington.
I have settled on the Federal 205M Match primers for all my 222 Remington heavy barrel Rifles.
I am shooting Varmint type bullets out of all my 222's now and shoot WAY more afield than at the range these days.
I also have several of the old style Leupold 36 power (and 24 power) Bench Rest type scopes in both silver and gloss finishes.
I like them even though they are a bit slower afield to get the adjustable objective range focus correct but once that is done - Varmints beware!
Once you run out of those Sierra 53's be sure to try the Berger 52 grainers.
They shoot wonderfully for me.
Enjoy that super cool, first rate Rifle - and thanks for sharing that amazing .071" grouping (screaming here!).
Hold into the wind
