I believe you could find a good load with that bullet and your 222 Rem using a charge of Trail boss. It would make a good and fairly quiet load and should be more than accurate enough for 100 or less shots.
Various manuals show the load area for Trail boss in various cartridges. You will find that that Dogtown bullet is a pretty good one, it actually is a Nosler Shot, standard cup and core hp, made for Midway and Midsouth for their bulk bullet sales. Bill K
