Good thread, started my 9 year old on a savage bolt 22 this year. I asked my myself the same question regarding scoping and went with irons, am glad I did. As someone mentioned, the LOP becomes less critical and being an old fashioned rifleman, I believe shooting with irons is a good fundamental to be had.
I listen to the Hal Blood podcasts occasionally, those Mainers still use irons and manage to get their venison.
